700–1250mm Pre Painted Steel Coil with 30–275g/m² Zinc Coating and 3–8MT Coil Weight for Roofing and Cladding Applications
700–1250mm Pre Painted Steel Coil with 30–275g/m² Zinc Coating and 3–8MT Coil Weight for Roofing and Cladding Applications
１．Product Overview
Pre painted steel coil is a color coated steel material widely used for roofing sheets, wall cladding panels, construction materials, home appliances, furniture panels, and industrial fabrication applications.
The product combines zinc coating and paint coating technology to provide corrosion resistance, surface durability, and decorative appearance. With 700–1250 mm width and 3–8 MT coil weight, the coil is suitable for continuous production lines and roll forming systems.
２．Technical Solution
The product is manufactured with zinc coating from 30–275 g/m² and coated with PE, SMP, HDP, or PVDF paint systems.
The 10–25 μm top coating improves weather resistance, surface protection, and color stability. The 5–7 μm back coating improves reverse-side protection during storage, transportation, and forming operations.
The RAL color system supports standardized color matching for roofing sheets, wall cladding, appliance panels, and decorative metal applications.
