Steel Powder Coating Services

Steel Powder Coating in PA

Powder coating is a finish for metal products that offer high chemical resistance. It’s made with a dry powder that’s electrostatically charged so that it sticks to metal. First, the dry powder is applied to a metal with a specialized spray gun. Once it’s been applied, the powder is cured with heat to create a smooth finish that resists corrosion and scratches.

Powder coated steel offers significant advantages over paint. For products intended for either interior or exterior use, powder coated steel delivers exceptional durability with a range of options to match any design specification.

The Benefits of Powder Coated Steel

Steel is excellent for building but susceptible to damage from a range of natural and manufactured elements. Powder coating uses a combination of positively charged fluidized powder and a negative charge fixed to your steel products to create an electrostatic bond. This bond holds throughout curing and provides complete coverage — much more effective than painting. 

Powder coated steel offers many valuable benefits, including:

  • Resistance to corrosion: We use coatings tested under severe conditions for maximum resistance to corrosion from salt, moisture and chemicals.
  • Protection against damage: Powder coating provides a hardened outer layer that is resistant to cracking, bubbling, peeling, chipping and other types of wear.
  • Eco-friendly impact: While paint produces destructive compounds and pollutants, powder coating is an eco-friendly process that is virtually pollutant-free.
  • Visual appeal: Powder coating creates a smooth, visually appealing final product. Not only does it protect steel, but it also makes steel products look polished and professional. 
  • Cost-effective procedure: This process is an affordable option for protecting steel components and machinery. It saves you on replacement and repair costs because it’s so durable and lasts for a long time.

Another benefit of powder coating is that it has a minimal negative health impact on workers. Powder coating doesn’t use solvents like wet paint, so it’s less toxic for employees who are applying it and nearby while it is drying. Wearing the proper protective equipment while applying powder coating to steel is important.

Powder Coating Steel FAQs

The processes for powder coating stainless steel and powder coating carbon steel follow many of the same steps, but the materials involved can vary. Metals with different compositions can have reactions to powders and treatments, and the right selection is critical to ensure a lasting coat and prevent delays in production.

The primary differences between powder coating these metals include:

  • Stainless steel: Stainless steel is resistant to natural corrosion, but if you plan on blasting for surface preparation, you must choose the right abrasives to prevent galvanic corrosion.
  • Carbon steel: Carbon steel is strong but susceptible to corrosion. For powder coating steel and regular carbon steel, you should consider adding a zinc-rich primer coat, particularly in outdoor environments.

Depending on how it’s engineered, applied and maintained it can last up to 15 years. If steel is prepared and evenly coated, you can expect a powder coating to last for a long time. Steel components that experience harsh environments may lose their protective powder coating more quickly.

When applied properly, powder coating will protect steel from rust. This coating creates a physical barrier that protects steel from corrosive moisture, preventing rust from forming. If this powder coating is damaged, rust can form along scratches and chips in the finish.

If steel isn’t properly cleaned before it’s coated, rust can form underneath the protective powder coat. To prevent rust, choosing a company that prioritizes best practices is essential.

Yes, powder coating is a good way to increase the durability of stainless steel. Although this type of steel is already corrosion-resistant, powder coating can keep it intact in harsh environments for longer. Because stainless steel is smooth, this kind of steel is often blasted with an abrasive first for better adhesion with the powder coating.

Galvanized steel already has a protective zinc coating that keeps corrosion at bay. However, powder coating this type of steel can enhance this protective barrier.

To powder coat galvanized steel, you must heat it to release gases that could ruin the powder finish. Once it’s been etched with abrasives for adhesion, the surface must be degassed for better appearance.

There are powder coatings specifically designed for galvanized steel that will adhere well to the zinc finish, ensuring a corrosion-free finish that protects your components in harsh environments.
