Professional Powder Coating Services for Your Business
Powder coating applies dry powder electrostatically to metal parts and cures it in an oven, creating a durable, uniform, environmentally friendly finish.
About Powder Coating
Powder coating is a dry finishing process where finely ground particles of pigment and resin are electrostatically charged and sprayed onto a grounded metal surface. The coated part is then heated in a curing oven (typically 350-400°F for 10-20 minutes), where the powder melts and flows into a smooth, durable finish. Powder coating produces a thicker, more uniform coating than conventional liquid paint, with excellent adhesion, impact resistance, and corrosion protection. It is more environmentally friendly than liquid paint because it contains no solvents (VOCs) and overspray can be recycled. Powder coating is the most popular finish for metal fabrications, furniture, automotive parts, and industrial equipment.

Powder Coating FAQ
How durable is powder coating?
Powder coating is significantly more durable than conventional paint, with excellent resistance to chipping, scratching, fading, and corrosion. A quality powder coat on properly prepared steel can last 15-20+ years outdoors and indefinitely in indoor environments.
Can powder coating be applied to aluminum?
Yes, aluminum is commonly powder coated. Proper pre-treatment (chromate conversion or non-chrome alternatives) is essential for good adhesion. Architectural aluminum (window frames, railings) is almost universally powder coated.
What colors are available in powder coating?
Powder coating is available in virtually any color, including custom color matching to RAL, Pantone, and proprietary color standards. Textures include smooth, wrinkle, hammer-tone, sand, and metallic. Gloss levels range from matte to high gloss.
Can powder coating withstand high temperatures?
Standard polyester powder coatings withstand continuous temperatures up to 200°F. High-temperature coatings (silicone-based) can withstand 500-1200°F and are used on exhaust systems, grills, and industrial ovens.
How should parts be prepared for powder coating?
Parts should be clean, dry, and free of oil, rust, and mill scale. Typical preparation includes degreasing, sandblasting or chemical etching, phosphate or chromate pre-treatment, and drying. Proper preparation is critical for coating adhesion and durability.
