6 Surfaces You Should Always Powder Coat (And 3 You Shouldn’t!)

Powder coating is a method rapidly increasing in popularity. This method applies a durable and protective finish to metal surfaces. It involves the application of a dry powder that is electrostatically charged and then sprayed onto the surface. The powder adheres to the metal, and then the coated surface is heated, causing the powder to melt and fuse into a smooth, even covering. Powder coating can be applied to various surfaces, but some textures are better suited to this method than others. Let’s explore the six best surfaces to powder coat — and three you should never touch!

6 Best Powder Coating Surfaces

Steel

Steel is one of the most common surfaces that is powder coated. It is durable, strong, and corrosion-resistant, making it an ideal material for various applications. Powder coating can be applied to various shapes and sizes of steel surfaces, including pipes, sheet metal, and wire.

Aluminum

Aluminum is a lightweight metal that is also resistant to corrosion. Powder coating can provide an additional layer of protection to aluminum surfaces, making them even more resistant to wear and tear. Aluminum surfaces that are often powder-coated include wheels, frames, and engine parts.

Iron

Iron surfaces are also suitable for powder coating. Iron is a strong, solid and durable material that can withstand a lot of wear and tear. Powder coating can provide additional protection against rust and other forms of corrosion. Iron surfaces that are often powder-coated include fences, gates, and decorative metalwork.

Brass

Brass is a metal alloy that is often used in decorative applications. Powder coating can provide a protective layer to brass surfaces, preventing them from tarnishing or rusting. Powder-coated brass surfaces are often used in decorative fixtures and hardware.

Copper

Copper is another metal that is often used in decorative applications. Powder-coated copper surfaces are often used in architectural and decorative elements. Powder coating can protect copper surfaces, preventing them from tarnishing or rusting over time.

Galvanized Steel

Galvanized steel is a steel surface treated with a zinc layer to protect against corrosion. Powder coating can be applied over the galvanized surface, providing additional protection. Powder-coated galvanized steel surfaces, such as fencing and signage, are often used in outdoor applications.

3 Surfaces to Never Powder Coat

While powder coating is a popular and effective method for protecting and enhancing metal surfaces, some surfaces should never be powder coated. These surfaces may not adhere well to the powder coating or be damaged during the powder coating process. This article will explore the three surfaces to never powder coat.

Wood

Powder coating is designed for metal surfaces and should never be applied to wood surfaces. Wood is a porous material that can absorb moisture, which can cause the powder coating to bubble and peel. The heat required for the powder coating process can also cause the wood to warp, crack, or burn. If you want to add a fun pop of color to a wooden surface, other coating options are available, such as paint or stain.

Plastic

Powder coating should also never be applied to plastic surfaces. Plastic cannot withstand the high temperatures required for the powder coating process, and it can melt or warp when exposed to heat. Additionally, plastic surfaces may not adhere well to the powder coating, which can cause the coating to peel or flake off. If you need to add color to a plastic surface, consider using a vinyl wrap or paint specifically designed for plastic.

Glass

Glass is another surface that should never be powder coated. The high temperatures required for the powder coating process can cause the glass to shatter or crack. Additionally, the powder coating may not adhere well to the glass surface, which can cause the coating to peel or flake off. If you want to add a unique flare to a glass surface, consider using glass paint or film.
