HOT DIP ALUMINUM COATED STEEL SHEET
1. PRODUCT FEATURES
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. Dongbu Steel produces hot-dip aluminum coated steel sheet under the brand name ALCOT. Dongbu Steel was awarded the Jang Young Sil award in September 1992 in recognition of top-quality technology, research endeavors in pursuit of original and independent technology parallel to that of advanced nations, and contributions to replacing imported materials with Korean products.
- Superior Heat Resistance : Lengthy exposure to temperatures up to 450 degrees Celsius causes very little change in ALCOT and does not affect its attractive surface brightness, compared with galvanized steel sheet and cold-rolled steel sheet.
- Superior Heat Reflectivity : The highly elegant surface of ALCOT 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 ALCOT the ideal choice for producing the heat reflector plates in toasters, oves, gas ranges and oil stoves.
