If you're fabricating metal parts and need them colored or covered in a protective coating, powder coating is the most effective option. This process uses a fine, dry powder, which is encouraged to adhere to the surface of the metal with an electrostatic charge. Then, heat is applied to permanently affix the coating, creating a thick, even layer across the entire part. Here are a few benefits to this approach over painting.

Why Should You Choose Powder Coating?

Precision

Because the process uses dry, airborne powder, the final coating is even and smooth. The surface won't accumulate excess covering and drip, as it might with a wet paint, nor will marks be left behind from the application, such as brushstrokes.

Durability

The coating produced using this method is thick and uniform across the whole surface, making it long wearing and tough compared to painted products. This is particularly an advantage when it comes to rust resistance, as there will be no thin spots in the coating which might let moisture through.

Convenience

Powder coating takes only a single application to produce a full-thickness layer of protection. This makes the process faster than painting, which often requires multiple coats for full coverage.

Control

If you need your parts to display multiple colors or textures, powder coating can easily achieve this. Multiple types of powder can be applied to different areas with fine precision, resulting in smooth, attractive patterns.

Safety

Powder coating is environmentally friendly because it takes place inside a closed booth, producing no environmental contamination. There are no volatile chemicals involved—just your coating, made of polyurethane, epoxy, or acrylics.
