Galvanized Steel Roofing Sheet Sizes
| Parameter | Typical Range | Notes |
| Thickness (t) | 0.35 – 1.2 mm | Most roofing sheets are 0.4–0.7 mm; thicker sheets are applied for industrial roofs. |
| Coating (Z) | Z60 – Z275 g/m² per side | Determines resistance to rust; for roofing normally Z120–Z180 are used. |
| Width (B) | 600 – 1250 mm (mill finish) | Roll-formed widths vary with the profile, the effective cover width is a bit less. |
| Length (L) | 2 – 12 m | Sells in Rolls to Customers Specifications. Long Sheet lengths minimize joints and leaks. |
| Spangle (Zinc coating appearance) | Regular / Minimized / Zero | Depends on the visuals. |
| Weight | 3–10 kg/m² | Depends on thickness and covering. |
