Turnstar has been operating a modern powder coating line for over 13 years and no powder coating is sent out to sub-contractors. With the process contained in-house, Turnstar is able to control quality, lead time and pre-treatment. Pre-treatment is the most critical and the most often overlooked aspect of powder coating as you can’t see the metal under the cured paint. Turnstar operates a state-of-the-art 8 tank pre-treatment plant which degreases, removes rust and scale and then coats the metal with a multi-metal phosphate. Shown here is a turnstile rotor after the chemical processing. The iridescent coating allows for great adhesion as well as corrosion protection.
