>>Heat resistance: Lengthy exposure to temperatures up to 450 degrees Celsius causes very little change in ALCOAT and does not affect its attractive surface brightness, compared to galvanized steel coil and cold-rolled steel coil.

>>Heat Reflectivity: Elegant surface of ALCOAT reflects about 80% of the heat at a temperature of 450 degrees Celsius. Its reflection rate goes up to 95% where infrared rays are present. This makes ALCOAT the ideal choice for producing the heat reflector plates in toasters, ovens, gas ranges and oil stoves.

>>Corrosion resistance: Aluminum tends to be more resistive than Mn, Mo, Cr, W, Cd, Fe, Zn. But because the aluminum oxide film itself has good stability, so the surface corrosion resistance in addition to part of the environmental conditions, much better than galvanized coil.

>>Green environmental performance: It's not harmful to human body, is an environmental protection product, aluminum plating plate can be fully recycled

>>Processing performance: Aluminized steel plates can be processed in the same way as other steel plates

>>Weldability: Because aluminum is soft, it is easy to bond, and because of its strong electrical conductivity, the welded part has excellent heat dissipation. In addition, because the coating is higher than the galvanized melting point, it is not easy to flow, and the melting area is small, so it is not necessary to use galvanized steel plate as high current

>>Surface appearance: It has a long-lasting shine, better corrosion resistance and weathering resistance.
