Powder Coat FAQ

What is powder coating?

Powder coating is a finishing process for metal materials. As the name suggests, powder coats are spray-on powder applications that are heated and bonded to metal surfaces. A good powder coat finish seals the product’s metal surface from corrosive contamination.

Why do aluminum posts need to be powder coated?

Simply put, aluminum posts need a powder coat to seal the surface of the metal from contaminants and to resist oxidation.

Corrosion and rust are often used interchangeably, but they aren’t the same processes. Aluminum contains no iron or steel, so it doesn’t truly rust, but it is susceptible to a different form of oxidation. Oxidation occurs when raw aluminum undergoes prolonged exposure, especially in moisture-rich environments. The oxidation process can begin quickly, so we’ve spared no expense to efficiently clean & prep our aluminum parts for powder coating to prevent against oxidation.

Powder coated metal posts

To ensure the finish on our posts is durable, beautiful, and long-lasting, we’ve developed a state-of-the-art cleaning & prepping process. We start by shot-blasting our posts to remove surface contaminants and even out any micro-inconsistencies on the surface of the material. Next, we rotate the posts through a series of chemical baths that leave the material surface immaculate and ready to receive the powder. After applying the powder coating itself, the final step is a computerized baking process that superheats and bonds the powder coating to the metal surface.

The results speak for themselves.

What’s the difference between standard and fluropolymer powder coating?

While fluoropolymer and standard powder coats go through the same process, the difference between the two lies in their chemical make-up. Fluoropolymer options will hold up better to color fading from UV light and environmental exposure. But, both options will seal a metal substrate from oxidation.

If your project is in a corrosive environment, you’ll want a fluoropolymer powder coat.

How do I maintain my powder coated system?

Your system will continue to look beautiful and optimally perform so long as your posts metal surface remains sealed and unexposed. Routinely cleaning your powder coated posts with gentle soap and water will be sufficient to maintain your system. Be careful to avoid harsh chemical cleaners, as these can damage the finish on your posts.
