タイトルまたは説明

Color steel doors and windows refer to the color coated building external coil plate (hereinafter referred to as "color plate") made by modern technology with cold-rolled galvanized plate as the base plate and coated with weather resistant high corrosion resistant surface layer as the raw material for the production of doors and windows. In China, only Baosteel, WISCO and a few enterprises in Guangdong and Beijing can produce this special material. Because the doors and windows are made of color steel, they are called color steel doors and windows. The color coated galvanized coil is cut into strips by a special unit, and then cold formed and continuously rolled into special-shaped pipes for closed doors and windows, and then deep processed into color steel doors and windows.
