700–1250mm Pre Painted Steel Coil with 30–275g/m² Zinc Coating and 10–25μm Top Coating for Corrosion Resistant Applications

700–1250mm Pre Painted Steel Coil with 30–275g/m² Zinc Coating and 10–25μm Top Coating for Corrosion Resistant Applications

１．Product Overview

Pre painted steel coil is a color coated steel material used for construction panels, roofing sheets, home appliances, automotive parts, furniture, electrical cabinets, and general industrial fabrication.

The product combines zinc coating, pre-painted surface treatment, and multiple paint coating systems to provide corrosion resistance, color appearance, and processing flexibility. With 700–1250 mm width, 3–8 MT coil weight, and 508 mm / 610 mm coil ID, it is suitable for continuous production lines and downstream sheet processing.

２．Technical Solution

The product uses zinc coating from 30–275 g/m² as the corrosion protection base, combined with PE, SMP, HDP, or PVDF paint coating for surface durability and appearance.

The 10–25 μm top coating provides color appearance and exposed-side protection. The 5–7 μm back coating improves reverse-side protection during storage, transport, fabrication, and installation.

The RAL color system supports consistent color selection for architectural panels, appliance shells, roofing sheets, and decorative metal products.
