Products & Specification.
Aluminized Steel |
Hot-dip aluminum coated steel sheet combines the mechanical properties of cold-rolled steel sheet with aluminum's high resistance retention, heat reflection, and superior rust resistance.
Superior Heat Resistance
Lenghty exposure to temperatures up to 450 degrees Celsius causes very little change in ALCOT and does not affect its acttractive surface brightness, compared with galvanized and cold-rolled steel sheet.
Superior Heat Reflectivity
The highly elegant surface of ALCOT reflects about 80% of heat at a temperature of 450 degrees Celsius. Its reflection rate goes up to 95% where infrared says are present. This makes ALCOT the ideal choice for producing the heat reflector plates in toaster, oven, gas ranges and oil stoves. |
