Product Specification

700–1250mm RAL Color Pre Painted Steel Coil with 30–275g/m² Zinc Coating and 3–8MT Coil Weight for Industrial and Architectural Use

１．Product Overview

Pre painted steel coil is a color coated steel material used for industrial and architectural applications, including roofing sheets, wall panels, appliance panels, automotive parts, furniture, electrical cabinets, and decorative metal products.

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 a zinc coating range of 30–275 g/m² and finished with PE, SMP, HDP, or PVDF paint coating.

The 10–25 μm top coating provides the main visible surface for color appearance and environmental protection. The 5–7 μm back coating supports reverse-side protection during storage, forming, and final installation.

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