ALCOAT steel is also named as aluminized steel, it is produced by carbon steel which is coated with aluminum-silicon alloy by hot-dip process. The aluminum coating provides resistance to high temperatures and a bright appearance. The silicon promotes better adherence of the coating to the base metal. Aluminized sheet and coil will maintain their bright appearance and provide long-term service at temperatures up to 900 degrees F which is higher temperature than comparable zinc-coated products. Even though aluminum corrodes faster than zinc, the oxide forms on aluminum adheres tightly which could protect the base metal.

Coating Layers of Alcoat Steel
T1 Aluminized Steel is a new type product which is widely used recent years. It contains 90% aluminium and 10% silicon. Also, it has good heat resistance, heat reflection and corrosion resistance, and its mechanical and physical properties are better than cold-rolled steel sheet.
Because of its superior performance, aluminized steel sheet has been widely used in our daily necessities. For example, automobile mufflers, household appliances, etc.

Characteristics
Alcoat steel sheet combines the mechanical properties of cold-rolled steel sheet with aluminum’s high resistance retention, heat reflection, and superior rust resistance.
>>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 sheet and cold-rolled steel sheet.
>>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 sheet.
>>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.
