| • | As shown in Table-1 compositions of coating baths, there are two types of hot dip aluminum steel sheet, "Pure aluminum type" and "Aluminum-Silicon alloy type". |
| • | Weather Resistant Alstar (hereinafter called W.R.Alstar) is "Al-Si alloy type". |
| • | Both compositions have almost equal corrosion resistance properties. W.R.Alstar has better corrosion resistance properties than hot dipped galvanized steel sheet (hereinafter called Galvanized) and hot dipped 55% Aluminum-Zinc alloy coated steel sheet (hereinafter called 55% Al-Zn) and thus is ideal for roofing and outer cladding applications. |
