Powder coating is a process in which finely ground, electrically charged particles of pigment and resin are sprayed onto a grounded piece of metal, after which the coat is cured to form a protective film. This process is widely used in the metal fabrication industry, particularly for steel frames and extrusions. Here are the benefits of powder coating steel.

How Does Powder Coating Help Steel?

1. Improved Durability

Powder-coated steel can bend and flex when exposed to vibration, making it highly resistant to scratching, cracking, and flaking. This gives it greater durability and flexibility than a standard painted finish and increases resistance to environmental hazards, impacts, and other potential damage. By protecting the underlying steel, the coating helps to extend its lifespan.

2. Corrosion Resistance

Direct exposure to moisture and humidity can quickly lead to metal corrosion, especially for outdoor applications exposed to rain, snow, and high humidity. However, steel and other metals that are powder-coated have corrosion resistance. A thorough, even powder coat keeps moisture from reaching metal pores, preventing the formation of rust and ensuring the structural integrity of the steel for many years.  

3. Adherence to Any Steel Product

Thanks to static electricity, powder coating achieves an even application to the entire steel surface—even for extrusions with hard-to-reach areas. The final coat is free of imperfections such as streaks or bubbles. Better still, the colors and textures are fully customizable. Whether you prefer a high gloss or matte finish or a smooth or wrinkled texture, it can be done. A wide range of powder pigments also enables the creation of custom colors to achieve the desired appearance for your application.
