Custom Cut JIS CGCC Prepainted Color Steel Coils for Mechanical, Electrical Equipment and Building Applications

1. Product Overview

Prepainted color steel coils are manufactured by applying an organic coating system onto galvanized or galvalume steel substrate to provide both decorative appearance and corrosion protection. The product is widely used in construction panels, appliance housings, transportation equipment, and industrial fabrication.

This specification covers custom cut PPGI and PPGL coils with widths from 700–1250 mm and thickness from 0.12–1.20 mm. Multiple RAL colors and processing services are available according to downstream production requirements.

2. Technical Solution

The product combines metallic substrate protection and paint coating protection through a multi-layer coating structure:

• Hot dipped galvanized or galvalume steel substrate

• Zinc coating range from 20–275 g/m²

• Primer and top paint coating system

• Polyester, SMP, or PVDF paint options

• Surface treatment including chromated, oiled, or anti-fingerprint finish

The coating system improves corrosion resistance, weatherability, surface durability, and color retention for indoor and outdoor applications.
