Since the coating can have various colors, it is customary to call the coated steel plate a color coated steel plate. A steel coil is harvested by the coiling machine. The paint used for color-coated rolls should be selected from suitable resins according to the use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride and so on. The user can choose according to the purpose.
Comparison of Color coated coil implementation standards at home and abroad.
China: GB/T12754-2006 Color Coated Steel Plates and Strips.
American Standard: ASTM A792M color-coated steel sheet implementation standard.
Japanese standard: JIS G3312 CGCC pre-coated hot-dip galvanized steel sheet and coil standard.
The use of color-coated coils in the market is mainly divided into three parts
construction, home appliances and transportation. The color-coated coils used in construction generally use hot-dip galvanized steel and hot-dip galvanized steel as substrates, and are mainly processed into corrugated board or sandwich panel with polyurethane. Later, it is used to construct roofs, walls, doors, etc. of industrial and commercial buildings such as steel structure factories, airports, warehouses, and freezers.
