A 1250mm width in galvanized steel coils is a standard dimension optimized for both manufacturing efficiency and end use applications. This width aligns with common roll forming equipment settings, allowing the production of panels and components with minimal material waste. In construction, 1250mm wide coils are ideal for roofing sheets (reducing seams in standard roof widths) and wall cladding, while in automotive applications, they fit door and hood stamping dies . The width is specified in standards like EN 10143, with tolerance typically ±3mm to ensure compatibility with downstream processes. Galvanized coils of this width are often produced in thicknesses from 0.3mm to 3.0mm, balancing formability with strength. For large projects, 1250mm coils enable continuous roll forming into long length products (e.g., 10m roofing sheets), reducing installation time. Logistics advantages include efficient container loading—multiple 1250mm coils can be stacked without overhang, minimizing shipping costs. Manufacturers may offer slitting services to customize widths, but 1250mm remains a cost effective default due to high production volumes and equipment standardization.
