The Quick frame Standard welding frame is made of black powder coated 3/4" Diameter galvanized steel in round tube framing. It's lighter in weight than our heavy duty frame for convenient mobility. Our snap-fit design allows for quick and easy assembly without the use of tools. New to the quick frame Standard is our hinge clip, making it easier for multiple panels to connect. Our safe-vu vinyl welding screens provide protection from sparks, as well as harmful UV rays and radiation. They are translucent for limited observation from passersby. Vinyl's are flame resistant and meet the requirements of NFPA701 and the California fire Marshall for flame resistance.
