Product Specification

Color Coated PPGI Steel Coil with 10–25μm Top Coating for Roofing Panels and Appliance Manufacturing

１．Product Overview

Pre Painted Steel Coil is a color coated steel material designed for roofing systems, wall panels, appliance housing, and industrial fabrication applications. The product combines galvanized steel substrate protection with continuous pre-painted coating technology to improve corrosion resistance, weather durability, and surface appearance.

The product is widely used in construction panels, household appliances, ventilation systems, and decorative metal fabrication where stable coating performance and long-term color retention are required.

２．Technical Solution

The steel substrate is processed through zinc coating and continuous color coating production lines. The zinc coating layer improves corrosion resistance, while the paint coating system enhances weather resistance, UV stability, and surface durability.

The 10–25μm top coating improves outdoor exposure performance and scratch resistance. The 5–7μm back coating improves reverse-side protection during transportation, forming, and installation.

Different paint systems are available according to service conditions. PE coating is suitable for general indoor and commercial applications. SMP and HDP coatings improve outdoor durability and weather resistance. PVDF coating is recommended for high UV exposure and corrosive industrial environments.
