POWDER COATING
Aluminum rails are an attractive addition to any residential or commercial space – and powder coating truly takes it to the next level. Powder coating is the ultimate and sustainable choice when seeking on a most reliable finishing option for aluminum. It is a dry finishing technique that involves applying electrostatically charged particles onto a substrate’s surface and contains a vast of advantages ranging from financial, mechanical to environmental. From classic gloss white to stylish speckled walnut, ProRailsUSA there are a wide variety of powder coating finish options for every outdoor aesthetic.

Cleaning: The process of achieving a superior quality finish starts with a quality pretreatment process. The high-performance washers from ProRailsUSA are the perfect foundation for your finishing system. Proper pretreatment helps to ensure excellent paint adhesion, increase finish quality, prevent corrosion, and improve powder coating performance.
Primer: A primer is an important process added to the surface before the powder coating application. The primer helps any scratches or dents from spreading to the rest of the railing. It also acts as another protection layer against rust and corrosion. This layer dries in place and seals the surface, readying it for the following stages of powder coating.
Coating and Curing

The coating process has an electrostatic spray gun generates the electrostatic charge difference resulting to the build-up and sticking of powder particles on Aluminum surface.
The Curing process melts the resins in the powder and turns it into a durable coating. The timing and temperature used for curing depend on the coating thickness, substrate material, item size, and other factors. Professionals use these aspects of the part to calculate the precise curing time.

After curing, the aluminum profile will be cooled down and will undergo quality checking to see if the paint is evenly. In our quality checking, several tests such as the scratch test, punch test, and microns test are done for to check paint surface thickness and adhesion.
