700–1250mm Pre Painted Steel Coil with 30–275g/m² Zinc Coating, 5–7μm Back

１．Product Overview

Pre painted steel coil is a color coated steel material used in construction, roofing sheets, wall panels, home appliances, automotive parts, furniture, electrical cabinets, and decorative panels.

The product combines zinc coating, paint coating, and pre-painted surface treatment to provide corrosion protection, color consistency, and convenient downstream processing. 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 sheet fabrication processes.

２．Technical Solution

The coil is produced with zinc coating from 30–275 g/m² and finished with PE, SMP, HDP, or PVDF paint coating.

The top coating thickness of 10–25 μm provides the main decorative and protective surface. The back coating thickness of 5–7 μm supports reverse-side protection during storage, forming, and service use.

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