700–1250mm Pre Painted Steel Coil with 10–25μm Top Coating and RAL Color System for Architectural and Industrial Applications
700–1250mm Pre Painted Steel Coil with 10–25μm Top Coating and RAL Color System for Architectural and Industrial Applications
１．Product Overview
Pre painted steel coil is a color coated metal material designed for architectural panels, roofing sheets, wall cladding systems, home appliances, and industrial fabrication applications.
The product combines galvanized or galvalume substrate with multi-layer paint coating technology to improve corrosion resistance, weather durability, and decorative appearance. With widths from 700–1250 mm and coil weights from 3–8 MT, the coil is suitable for roll forming, profiling, and continuous industrial production lines.
２．Technical Solution
The product uses zinc coating from 30–275 g/m² combined with PE, SMP, HDP, or PVDF paint systems for environmental protection and surface durability.
The 10–25 μm top coating improves UV resistance, color stability, and scratch resistance. The 5–7 μm back coating improves reverse-side corrosion protection during storage, transportation, and fabrication.
RAL color system control supports stable color consistency for roofing sheets, façade panels, appliance shells, and decorative metal products.
