Painting & Finishing

Regardless of your part protection requirements, BTD has a solution for you. BTD offers state of the art, production powder coating systems in multiple locations. In our MN locations, we offer a CNC controlled powder coating paint system that includes an in-line shot blast and wash system. In our GA facility, we offer an Autophoretic (A-Coat) liquid primer system with Powder top-coat. We meet or exceed our customers most demanding salt spray requirements.

Our state of the art powder-on-powder coating process is designed to deliver superior results. As a customer, you have the option to use or bypass an in-line automated shot-blast system in conjunction with a 7 stage wash system. We also offer one of the largest in-house part window profiles available in the metal fabrication industry. With a part window of 15’ long X 6’ tall X 4’ wide, we can handle projects both large and small.
