SA1D For Heat Resistance commercial quality hot dip aluminum coated steel coil
Aluminum plate, also called aluminum plate. Some people also call it aluminized sheet or hot-dip aluminized sheet.
Aluminum-plated steel plate is a steel plate coated with aluminum-silicon alloy, in which the aluminum content is 90% and the silicon is 10%.
Aluminized steel sheet has good heat resistance, heat reflectivity, corrosion resistance, and its mechanical and physical properties are better than cold-rolled steel sheets.
Due to the superior performance of aluminized steel plate, it has been widely used in our daily necessities. Such as car mufflers, household appliances, etc.

purchaser and the manufacturer.
Auto parts, thermal equipment, building materials, etc.
The full name of aluminized steel sheet is "hot-dip aluminized steel sheet", which is similar to hot-dip galvanized steel in terms of manufacturing process.
But its heat resistance is better than galvanized steel.
Depending on the application, in order to further enhance the corrosion resistance of the material, there are also special specifications that have passed surface post-treatment (chromate treatment, no (hexavalent) chromium treatment).
