What Is Powder Coating?
The Complete Guide to Durable, Eco-Friendly Metal Finishes by H-Town Coaters

Powder coating has become the gold standard for protecting and beautifying metal surfaces across nearly every industry. From industrial machinery and commercial railings to architectural façades. At H-Town Coaters, we’ve built our reputation on combining cutting-edge technology, expert craftsmanship, and eco-friendly practices to deliver coatings that are as strong as they are stunning.

This comprehensive guide will walk you through what powder coating is, how it works, and why it outperforms paint, while showing how it’s used across the industries we proudly serve throughout Houston, Texas, and the Gulf Coast.

What Is Powder Coating?

Powder coating is a dry finishing process that uses electrostatically charged powders. It is made of resins, pigments, and curatives to form a tough, seamless, and protective layer over metal.

Unlike paint, it contains no solvents or VOCs. When cured at high heat, the powder melts and bonds permanently to the surface, creating a finish that’s:

• Resistant to corrosion, fading, and scratches

• Uniform and smooth without drips or runs

• Environmentally friendly and long-lasting

How the Powder Coating Process Works

Our advanced coating process is designed for precision, consistency, and durability — no matter the project size or material.

1. Surface Preparation

We thoroughly clean, sandblast, or chemically treat every item to remove dirt, oil, and rust.

4. Curing

The coated part is baked at 350–400°F, fusing the powder into a solid, durable film.
