It's a relatively simple and inexpensive option, yet not all OEMs consider an e-coat an important part of their fabrication process. As the advantages and benefits of this protective metal coating grow, so does its implementation.

What follows is a comprehensive look at the process of e-coating.

How E-Coating Works

E-coating, also known as electrocoating or electrophoretic deposition, is a highly efficient and technologically advanced method of applying a protective coating to various materials.

The E-Coating Process

This process involves several key steps that ensure a thorough and efficient coating application. Understanding these steps will provide insight into the complexity and effectiveness of this coating method.

Pre-Treatment

Before the actual e-coating process begins, proper pre-treatment is essential to prepare the substrate for coating. This step typically involves cleaning the surface to remove contaminants such as dirt, grease, or rust.

The goal is to create a clean, uniform surface to promote adhesion and enhance corrosion resistance. Common pre-treatment methods include degreasing, alkaline cleaning, acid etching, phosphating, or sandblasting.

Masking

Certain substrate areas may need to be protected from being coated because of functional requirements or design specifications. Masking involves applying specific materials like tapes, plugs, or specialized coatings in these areas before entering the e-coating tank.

Masking ensures that only desired surfaces receive the protective coating while preserving critical features or sensitive components.

Electrolyte Bath Immersion

Once prepared and masked, the substrate is immersed in an electrolyte bath containing electrically charged particles of paint known as colloidal particles or a paint emulsion called slurry.

These particles consist of resin binders and pigments dispersed in water-based solutions.

Electrodeposition

Metal Substrate Being E-Coated.

The heart of e-coating lies in electrodeposition: an electrical current applies to drive the charged paint particles toward the oppositely charged substrates.

The positively charged anodes are present throughout the tank, while substrates act as negatively charged cathodes. As current flows through the electrolyte bath between these electrodes under carefully controlled conditions (voltage and time), electrochemical reactions occur at both ends, resulting in paint deposition on the substrate surface through an attraction force known as electrophoresis.

This deposition process enables a uniform and even coating thickness, reaching even the most complex shapes and recessed areas.

Post-Rinse and Curing

Once the desired coating thickness is achieved, the coated parts are rinsed with clean water to remove any excess paint particles or electrolyte residue.

This step ensures a clean, residue-free surface while preventing any potential contamination or adverse effects during subsequent curing processes. Following rinsing, the coated substrates undergo curing to complete the coating's mechanical properties and overall performance.

The curing process involves baking the coated parts in ovens at specific temperatures for a predetermined duration. This thermal treatment promotes cross-linking of the paint particles, enhancing adhesion, durability, corrosion resistance, and other desirable final coating properties.

The e-coating process encompasses these steps meticulously to ensure a high-quality and consistent outcome. From pre-treatment to electrodeposition and post-rinse with subsequent curing, these sequential stages play a crucial role in achieving exceptional protection for various substrates across multiple industries while offering environmental advantages because of their water-based nature.

Corroded metal surfaces often require intensive cleaning and preparation before effectively treating them with these protective coatings. Failure to adequately address corrosion issues during surface preparation may lead to poor adhesion of coatings, compromising their effectiveness and causing rework or complete re-coating. These additional steps extend production time and incur extra costs.
Metal fabrication often involves welding and joining various components together.

But corrosion in welded joints poses a serious concern as it weakens the bond between metals, making them more susceptible to failure under stress or environmental conditions. In such cases, additional measures are required to retard corrosion at welded joints through techniques like special coatings or sacrificial anodes.

However, implementing these measures requires careful planning and execution during fabrication; otherwise, delays may occur because of necessary adjustments or rework. When metal fabrications are exposed to corrosive environments during storage or transportation before installation, accelerated oxidation could compromise their performance later.

Extended exposure times may result from unforeseen circumstances, such as logistical challenges or unexpected project delays. Protecting metal components during these stages becomes crucial, using appropriate packaging or temporary corrosion prevention techniques.

Failing to account for such measures leads to production delays, as damaged or corroded parts cause repair or replacement. Production delays caused by corrosion in metal fabrication projects occur for various reasons.

These include the need for component replacement or repair, time-consuming surface preparation for coating applications, complications associated with corrosion in welded joints, and issues arising from exposure to corrosive environments during storage and transportation. By addressing these challenges proactively and implementing preventive strategies like proper surface treatment, protective coatings, and careful handling during storage and transportation, manufacturers mitigate the risk of production delays caused by corrosion in metal fabrication projects.

Repair Expenses

In metal fabrication, projects can significantly burden businesses, as corrosion damage causes costly repairs and maintenance. Corrosion, caused by various environmental factors such as moisture, chemicals, and temperature fluctuations, compromises metal components’ structural integrity.

Consequently, companies must allocate substantial resources to address these issues promptly and effectively. One of the most common approaches to repairing corroded metal components is through surface treatment techniques.

These techniques aim to remove existing corrosion and protect the metal from further damage. Electrostatic coating is often employed as a repair method, where an electric charge attracts paint particles onto the metal surface evenly.

This technique provides a visually appealing finish and acts as a protective barrier against future corrosion. Powder coating is another widely used repair technique in the industry.

A dry powder containing pigments and resins is applied electrostatically to the metal surface. The coated part is then heated, allowing the powder to melt and form a durable protective layer over the corroded area.

Powder coating offers superior resistance against corrosion while providing an attractive finish that mimics different textures or colors. Sometimes, e-coat/topcoat systems are employed for repairing corroded parts in metal fabrication projects.

E-coating involves immersing the components in an electrically charged bath containing paint particles that adhere uniformly because of their opposite charges for the coated part. After e-coating, a topcoat layer may be applied for additional protection or aesthetic purposes.

Despite these effective repair techniques, it’s important to note that repair expenses are not limited solely to material costs but include labor costs associated with disassembling parts for treatment or replacement. These costs significantly increase in complex structures or large-scale projects, such as bridges or industrial equipment.

Sometimes repairing corroded metal components may not be workable or cost-effective because of extensive damage or structural compromise caused by corrosion. Complete component replacement becomes necessary in such cases, leading to even higher repair expenses.

Repair expenses in metal fabrication projects are a significant concern because of the corrosive nature of many environments. Businesses use various surface treatment techniques, such as electrostatic coating, powder coating, and e-coat/topcoat systems, to address this challenge effectively.

However, companies must consider the material and labor costs of these repairs. Mitigating corrosion risks through preventive measures minimizes repair expenses and ensures the longevity of metal components in fabrication projects.

Denique

Addressing the challenges faced with corrosion in metal fabrication projects is crucial for ensuring successful outcomes. While material costs can be a concern, investing in corrosion-resistant materials such as stainless steel or aluminum significantly reduce long-term expenses associated with maintenance and repairs. Implementing preventive measures like proper surface preparation and applying protective coatings like powder coating, e-coat/topcoat, or electrostatic coating enhances the durability of metal components.

Production delays caused by corrosion issues can be mitigated through efficient planning and scheduling. By incorporating regular inspections and maintenance into project timelines, potential corrosion-related disruptions can be identified early, allowing prompt remedial actions.

Collaborative efforts between design engineers, fabricators, and clients must ensure adequate corrosion protection measures are incorporated from the design stage. Repair expenses stemming from corrosion damage can be minimized by promptly addressing any signs of deterioration.

Its advantages over traditional liquid paint, including superior durability, versatility in finishes, environmental friendliness, and efficiency, make it a preferred choice in many industries. In the following sections, we delve deeper into the powder coatings available and the surface preparation and application processes involved in achieving optimal results.

Types of Powder Coatings

Powder coating is a versatile finishing technique that offers a wide range of options, depending on the desired application and performance characteristics. Understanding the different powder coatings available is essential for making informed decisions in various industries. Two major categories are commonly used: thermosetting powders and thermoplastic powders.

Thermosetting Powders

Thermosetting powders are the most widely used type of powder coating because of their exceptional durability and resistance to heat, chemicals, and weathering. Among the thermosetting powders, three prominent variations stand out: epoxy-based powders, polyester-based powders, and polyurethane-based powders.

Epoxy-Based Powders

Epoxy-based powders are known for their excellent mechanical properties and exceptional corrosion resistance. These coatings provide a tough, protective layer withstanding harsh environments. Epoxy powder coatings find applications in the automotive, aerospace, and electronics industries, where resistance to chemicals and abrasion is crucial.

Polyester-Based Powders

Polyester-based powders offer outstanding outdoor durability with good UV resistance and color retention. They provide excellent protection against fading caused by exposure to sunlight or harsh weather.

Polyester powder coatings come in various finishes, like smooth, textured, or metallic effects. They are commonly used in architectural applications such as window frames, fencing, and outdoor furniture.

Polyurethane-Based Powders

Polyurethane-based powders combine the advantages of epoxy and polyester materials. These coatings offer exceptional toughness along with excellent chemical resistance and flexibility.

Polyurethane powder coatings withstand impacts without chipping or cracking while providing good color retention even under prolonged exposure to ultraviolet light. They are commonly used in the automotive industry for applications such as wheels, bumpers, and interior trim parts.

Thermoplastic Powders

Thermoplastic powders differ from thermosetting powders in that they can be repeatedly melted and solidified without chemical change. This characteristic makes them highly versatile and allows for easy reprocessing. Two commonly used types of thermoplastic powder coatings are nylon-based powders and polyethylene-based powders.

Nylon-Based Powders

Nylon-based powders offer excellent mechanical properties, including high-impact resistance and flexibility. These coatings exhibit good resistance to chemicals, solvents, and abrasion. Nylon powder coatings find applications in various industries, such as healthcare, appliances, sporting goods, and electrical components, where a combination of durability and aesthetics is required.

Polyethylene-Based Powders

Polyethylene-based powders provide exceptional electrical insulation properties along with good chemical resistance. These coatings have low surface energy, making them highly resistant to dirt or staining. Polyethylene powder coatings are widely used in the wire & cable industry for insulation or as functional coatings on metal substrates where lubricity or non-stick properties are desired.

Surface Preparation for Powder Coating

Proper surface preparation is essential for achieving a high-quality, long-lasting powder-coating finish. Inadequate or improper surface preparation leads to adhesion issues, poor coating performance, premature failure, and wasted time and resources. Ensuring thorough surface preparation creates an optimal foundation for the powder coating process.

Steps involved in the surface preparation process:

Cleaning and Degreasing the Surface

The first step in the surface preparation process is cleaning the substrate to remove contaminants that could interfere with adhesion—including dirt, oil, grease, dust, fingerprints, and other residues that may be present on the material's surface.

Various methods can be employed for cleaning, depending on the size and characteristics of the substrate. These methods include solvent wiping, alkaline cleaning solutions, pressure washing, or abrasive blasting.

Removing Rust, Scale, and Old Coatings

It is crucial to eliminate any rust or scale on metal surfaces to achieve a smooth and even powder-coating finish. Rust undermines adhesion and leads to coating failure over time.

Mechanical methods such as sanding or wire brushing are commonly used to remove loose rust or scale. For more extensive rust or thicker scale buildup, abrasive blasting techniques using materials like aluminum oxide or steel grit may be necessary.

Besides rust removal, any old coatings or layers on the substrate should also be removed before powder coating application, which typically involves stripping off previous paint layers through processes such as sandblasting or chemical stripping.

Etching or Chemical Treatment for Better Adhesion

Etching or chemical treatment may be required for certain substrates, like aluminum or galvanized steel, that do not offer ideal conditions for adhesion because of their inherent properties (oxidation resistance). Etching involves applying an acidic solution to the substrate's surface, which creates a microscopically rough texture and promotes better powder coating adhesion. Chemical treatments, on the other hand, involve applying specific solutions that chemically react with the substrate's surface, creating an anchoring effect for the subsequent powder coating.

These treatments are particularly useful when dealing with challenging or non-porous materials. Surface preparation is a critical step in achieving a successful powder coating application.

It ensures proper adhesion and helps maximize the performance and longevity of the finished product. By thoroughly cleaning and degreasing surfaces, removing rust and old coatings, and employing etching or chemical treatments when necessary, you create an ideal foundation for a flawless powder coating finish that will withstand the test of time.

Powder Coating Application Methods

Electrostatic Spraying Technique

The electrostatic spraying technique is one of the most widely used methods for powder coating application. It involves using an electrostatic charge to enhance the adhesion and uniformity of the powder on the surface. Two common methods for charging the powder particles are corona charging and tribocharging.

The Corona Charging Method

This method applies a high voltage to a metal electrode near the powder spray gun. As the powder passes through this electric field, it becomes charged with positive ions. The charged particles are then attracted to grounded or negatively charged surfaces, ensuring an even and consistent coverage.

The Tribocharging Method

Unlike corona charging, tribocharging does not rely on external electrical sources. It involves frictional contact between the powder particles and a material electrostatically charged with the opposite polarity. The friction causes electrons to transfer between surfaces, resulting in a charge imbalance that attracts the powder particles toward grounded or oppositely charged surfaces.

Efficiency

The wonders of the fluidized bed dipping technique offer an alternative method for applying powdered coatings. In this process, preheated parts are immersed into a bed of fine powdered material kept in a fluid-like state by forced air or gas flow through tiny holes in a permeable membrane at the bottom of the bed.

Overview

As parts are dipped into the fluidized bed, they displace some powdered material that adheres to their surface because of static electricity from thermal energy transfer during immersion. Excess powder is later removed using compressed air or other methods before curing.

This technique is especially suitable for coating objects with complex shapes, as the fluidized bed allows for uniform coating even on recessed or difficult-to-reach areas. It also enables the application of thicker coatings compared to other methods.

Advantages and Limitations

One major advantage of fluidized bed dipping is its ability to create thick, durable coatings in a single operation. The process is relatively quick and requires little operator skill.

The excess powder is easily reclaimed and reused, reducing waste and costs. However, this method may not be suitable for all surfaces or objects because of limitations in controlling film thickness and achieving precise coating thicknesses.

It is more commonly used for larger parts instead of smaller components because of equipment size requirements. The electrostatic spraying technique (through corona charging or tribocharging) and fluidized bed dipping offer effective ways to apply powder coatings.

Choosing the right method depends on several reasons, such as part size, shape complexity, desired coating thickness, and overall production requirements. By leveraging these advanced application methods, manufacturers achieve high-quality finishes that are visually appealing and provide excellent durability and protection against corrosion.

Curing Process in Powder Coating

Heat Curing

Heat curing is a common method used to cure powder coatings and is known for its reliability and effectiveness. The process involves exposing the coated component to elevated temperatures in a curing oven.

Different curing ovens are used in the industry, each with its own characteristics and benefits. One commonly used type of curing oven is the convection oven.

These ovens use heated air circulation to disperse heat throughout the oven chamber, ensuring uniform powder coating curing. Another type is the infrared (IR) oven, which uses infrared radiation to rapidly heat the coating surface.

IR ovens are preferred when quick curing times are required or when coating heat-sensitive substrates. The temperature and time requirements for heat curing vary depending on several factors, such as the type of powder coating, substrate material, and desired finish properties.

Typically, the curing temperature ranges from 300 to 450 ºF (150 to 230 ºC), lasting around 10 to 30 minutes. Following manufacturer recommendations for specific powder coatings is crucial to achieve optimal results.

Ultraviolet Curing

In recent years, ultraviolet (UV) curing has gained popularity in certain applications because of its unique advantages. This method involves using UV light sources instead of heat for polymerization and cross-linking of the powder coating. UV-curable powders consist of photo-initiators that react when exposed to UV light, resulting in rapid cure times.

UV curing is preferred in industries where fast production turnaround time is essential, such as electronics or automotive manufacturing. The instantaneous nature of UV curing allows for immediate handling and packaging after application without waiting for cooling down periods like with heat-cured coatings.

While UV-cured powder coatings offer many advantages, such as energy efficiency because of no heat requirements and reduced volatile organic compound (VOC) emissions, there are also challenges to consider. UV curing requires specific equipment, such as UV lamps or LEDs, which is costly to install and maintain.

UV curing is best suited for flat or relatively uniform surfaces because of the limited penetration of UV light. Complex shapes or deep recesses may not receive adequate curing, compromising coating quality.

Heat and UV curing play essential roles in the powder coating industry. Heat curing provides reliability and versatility, whereas UV curing offers rapid cure times and energy efficiency benefits.

The choice between the two depends on factors such as production requirements, substrate compatibility, and desired finish properties. Understanding these differences allows for informed decision-making when selecting the appropriate curing process for specific applications in powder coating.

Powder Coating Quality Control

Quality Control Inspection Techniques

Visual Inspection

Visual inspection is a fundamental step in ensuring the quality of powder coating. A trained eye detects imperfections such as bubbles, pinholes, or uneven coating application.

Inspectors meticulously examine the surface of the coated component under proper lighting conditions to identify any flaws that may compromise the final finish. This process involves checking for color uniformity, texture consistency, and any visible defects that could affect the overall appearance and durability of the coating.

Film Thickness Measurement

Accurate film thickness is crucial to achieving optimal performance and protection. Specialized devices like electronic gauges or magnetic induction instruments are used to accurately measure film thickness.

These instruments gauge the thickness by analyzing variations in electrical resistance or magnetic fields caused by powder coatings on a substrate. Regular monitoring ensures compliance with industry standards and avoids issues such as inadequate protection against corrosion or excessive material usage.

Adhesion Testing

Adhesion testing assesses how well powder coatings bond with a substrate surface. Various methods are available depending on factors like coating type and intended application. For instance, crosscut tape tests involve making precise cuts through the coated surface with a defined pattern before applying an adhesive tape that is quickly removed.

The extent of coating removal shows adhesion strength. Another method uses pull-off testers that measure adhesion strength by applying a force perpendicular to the coated surface until separation occurs.

Environmental Considerations

As responsible stewards of our environment, we must consider proper disposal methods for excess powder coatings. Unusable powders should never be discarded carelessly but collected and disposed of according to local regulations governing hazardous waste materials.

Recycling programs for powder coatings are available in some areas, allowing for the recovery and reuse of unusable or excess powders. Adhering to these practices minimizes the environmental impact and promotes sustainable powder coating practices.

Denique

Quality control is integral to powder coating processes to ensure that the final product meets the desired standards. Manufacturers identify and rectify flaws or deviations through meticulous visual inspection, film thickness measurement, and adhesion testing.

Environmental aspects, such as proper disposal of excess powder, promote sustainable industry practices. By upholding rigorous quality control measures and caring for our environment, we are committed to excellence in powder coating applications while safeguarding our planet for future generations.

5 Things You Didn't Know About Electrophoretic Coating

Tue, 06 Dec 2022 12:30:00 GMT

Electrophoretic coating started appearing inside steel food containers in US manufacturing in the 1930s. It took another 30 years before the other industries started e-coating, too.

It's an excellent history. However, e-coating wasn't contained just to the metal fabrication industry; it spread.

Here's an overview of the electrophoretic process.

What is Electrophoretic Coating?

We define electrophoretic coating as:

Electrophoretic deposition (e-coating/electric coating) is like electroplating. The electroplating process uses electric current reducing dissolved metal cations, forming a thin, coherent metal coating.

Electrophoretic Coating Applications

Paper and Paperboard Coating: Used on paper and paperboard to finish the paper to get a matte finish and high gloss and for printing on different papers and board substrates—as long as they can accept a coating.
Metal Coating: Used for coating metals for corrosion resistance, paint adhesion, and decoration in industries like automotive, aerospace, marine, and solar.
Plastic Films: Used for coating plastic films and sheets for increased strength, toughness, and barrier properties.
Printing on Fabrics: Used for fabric printing to get water-repellent properties.

Pros of Electrophoretic Coating

Works with many substrates
It's inexpensive: pennies on the dollar
Applied by immersion, roll coating, and web coating
No solvents are involved in this process, which means it is eco-friendly and doesn’t generate harmful fumes
Results in a smooth coating with a high gloss
It is highly effective for the decorative finishing of paper

Cons of Electrophoretic Coating

Limited color range compared to other coating processes.
The process takes longer if finishing companies have separate lines for their powder coat and e-coat. Operators must transfer the parts to the powder coat line after curing the parts.
It is not good for porous coating substrates.
It is not suitable for coating substrates sensitive to heat.

5 things you didn't know about electrophoretic coating

The positive and negative charges in curable e-coat originate from ions present naturally in water-based coating compositions. They attract the ions to opposite poles of a charged electrode.
EPC is a water-based process that uses positively charged particles suspended in a liquid to create a charged image on the surface of the substrate. In an EPC coating system, a negatively charged electrode attracts the positively charged particles, which are then attracted to the positively charged electrode.
Using a strong electric field speeds up the charged particles' movement, allowing them to adhere to its electrode. The e-coating process ends with a trip through curing ovens.
Industries also e-coat finishing paper to get a matte finish and high gloss for printing on different substrates like plastics, metals, and fabrics.
It is important to note that e-coating doesn't work well with porous substrates.

Test e-coat strength

To test the strength of an e-coat, the companies use one or some of these tests:

Taber Abrasion: Taber Abrasion is a test using a wheel containing sandpaper and applying it on the product's finish to see how many times the wheel goes before completely wearing it out. When placing the part vertically with a flat surface, the wheel is in contact with the entire surface simultaneously, and the test lasts longer.
The DIN Abrasion: The DIN Abrasion is a test done for the same purpose as the previous one. The only difference is the wheel—it's smaller and made of rubber.
The Pin and Swell Test: The Pin and Swell Test is a bottle production quality control test. In this test, QA techs poke a hollow needle into the product to check whether the e-coat has come in contact with the product or not.
Salt Spray Testing: Another method for measuring the strength of a topcoat is an extended salt spray test. (Author's Note: One of our clients requires us to use this testing method, which you see on our testing page.)

Conclusion

Don't you hate it when someone asks you a question with many different answers, yet the only thing you can say is, "it depends."

An e-coat's durability depends on the type of metal, the ability of the company to apply the coating, and the environment the metal finds itself.

Companies do their best to replicate those environments, giving themself a chance to test their methodologies.

So, in this case, when asking how long an e-coat last, sigh, it depends.

Can You Actually Avoid the Curse of Catastrophic Corrosion Concerns?

Building beautiful metal structures brings challenges unique to metal craft. As we’ve explored, exposed metal in a corrosive environment comes at a cost: corrosion.

Fortunately, there are several ways of protecting metal in such harsh and surprisingly not-so-hard, environments, and we’ll touch on those protective measures in this article.

Protective Coatings: the Series

For a more in-depth review of protective metal coatings, I invite you to follow this link to a series of articles we’ve shared. For now, though, here’s a brief look at this industry.

Not Just Ugly on the Surface

Corrosion isn’t just ugly; it’s expensive. Worldwide, it costs an estimated 2.2 trillion dollars each year to control corrosion, roughly 3% of the world’s gross domestic product.

Corrosion isn’t just ugly and expensive; it’s dangerous. It challenges our safety from affected roads, buildings, and bridges. Corrosion prevention becomes an essential aim.

Strategies to Fight Corrosion

There are many ways to fight rust, but for this article, we’ll focus on ten:

Painting
Galvanization
Alloy
Coating with Oil
Proper Storage
E-Coating
Powder Coating
Bluing
Packaging

Painting

Simple paint covers a substrate, but it needs to accomplish more than making it look good. If you know moisture exposure exists, water-based paint is less than ideal. You must also ensure the paint sticks to metal while monitoring areas where a finish exists.

Galvanization

Applying a zinc coating to iron or steel using galvanization is the most common way to protect the metal. Zinc corrodes at a much slower rate than iron and is economically viable.

Alloys

All metal rusts and some metal rusts slower than others. When combining two metals, it creates alloys. The best example of rust protection using an alloy is stainless steel—basically a rust-resistant metal.

Coating with Oil

An oil coating not only lubricates but also protects the metal. Oil creates a protective barrier, preventing moisture from reaching the substrate.

Proper Storage

Storing metal components in a dry or low-moisture environment slows the process of corrosion.

E-Coating

An e-coat is like electroplating, where an electric current is added to epoxy, water-based solution, or paint while dipping the substrate into a bath. The effect is a near-complete bath for the metal, coating hard-to-reach areas.

Powder Coating

Using current to adhere paint powder, followed by curing, creates an extremely tough barrier against moisture.

Bluing

Bluing steel has existed for hundreds of years, the earliest examples in ancient Japanese swords. Bluing steel describes applying a black oxide coating to a metal substrate, resulting in a blue-black appearance of the resulting finish.

VCI Packaging

Vapor corrosion inhibitors (VCI) are chemical compounds that protect metals from rust and corrosion. Infusing VCIs with poly films, chipboard, paper, etc., activates and ‘fill-up’ vapor space inside the packaging, forming a shield of protection displacing moisture. Properly used, VCIs eliminate excess grease or oils, making uncrating components time-consuming.

Each of these methods of protecting metal works well enough on its own. However, there are significant limitations and challenges. Combining any of these processes creates a formidable protective barrier. An e-coat/powder coat combination is one of the most effective barriers to combating corrosion.

In Sum

Combining protective coatings with a good maintenance program certainly is an effective way to combat rust. Corrosion is a natural process that reverses metal to its original state. Rust weakens the metal, endangering people and structures, and protecting metal has become a multi-billion-dollar industry.

There are hundreds of ways to improve the lifespan of metal architecture, and each has its advantages and limitations. Approaching the problem using a holistic approach is the right way to start. Component design and geometry, environmental factors, and metal selection are vital ingredients for a successful and sustainable project.
