700–1250mm Pre Painted Steel Coil with RAL Color System and 10–25μm Top Coating for Construction and Appliance Applications
700–1250mm Pre Painted Steel Coil with RAL Color System and 10–25μm Top Coating for Construction and Appliance Applications
１．Product Overview
Pre painted steel coil is a color coated steel product designed for construction materials, home appliances, automotive components, furniture panels, and decorative metal applications.
The pre-painted surface treatment provides corrosion resistance, color consistency, and decorative appearance while supporting efficient downstream processing. With width options from 700–1250 mm and coil weights from 3–8 MT, the product is suitable for continuous production lines and industrial fabrication 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 provides surface protection, weather resistance, and color durability. The 5–7 μm back coating improves reverse-side corrosion protection and processing stability.
The RAL color system supports standardized color matching for roofing panels, wall cladding, appliance shells, and architectural decoration.
