The cold rolled steel coil factory in stock introduces that the traditional coatings can be divided into several categories. The top-grade coatings are fluorocarbon coatings, which can resist corrosion for almost 20 years. Generally from steel mills to distribute in the form of drums. We often see the color steel plate refers to the processed plate, the thickness of which is about 50 to 100 mm. It is composed of filler in the middle and color steel plate on both sides.
Among them, the thickness of the color plate is 0.4mm, 0.5mm, 0.6mm and other different thicknesses. The middle layer can be polyurethane, rock wool or foam plastics. Because of the special profiles, the construction speed of the factory building constructed with color steel sheets is very fast (such as Xiaotangshan Hospital in SARS), but the strength is low. The base plate of color coated steel sheet is cold rolled, hot galvanized and electro galvanized. The types of coatings can be divided into polyester, silicone modified polyester, polyvinylidene fluoride, and plastic sol.
