Product introduction


Prepainted Galvanized Aluminum Zinc Coated Steel Coil (AZ): It has excellent coating insulation protection and electrochemical protection. Higher corrosion resistance in most environments and long-term durability. Suitable for environments requiring higher corrosion resistance. In addition, the coating has good high temperature resistance and heat reflectivity. The coated steel coil is widely used in roofing and walling, and can be used directly or as a substrate for color-coated panels.

Other applications of this coated steel include:

  • Building and construction components (envelope systems, joists for residential buildings, roofs, walls, ceilings, doors);

  • Rainwater pipe fittings;

  • furniture and outdoor cabinets;

  • Unexposed auto parts;

  • Electrical appliances (oven, heater);

  • Pipes and computer cases, etc.
