Color Coated Galvanized Corrugated Sheet — Durable Roofing & Cladding Material

Color coated galvanized corrugated sheet is a widely used roofing and exterior wall material that combines the strength of galvanized steel with protective paint coatings. Its lightweight structure, high durability, and excellent corrosion resistance make it ideal for construction projects in various environments—from humid coastal regions to industrial zones.

Product Overview

These corrugated sheets are produced by coating galvanized steel with premium-grade paint systems such as PE, SMP, HDP, or PVDF, offering long-lasting resistance against UV rays, moisture, chemicals, and harsh weather conditions.

The corrugated profile increases sheet rigidity, allowing for strong load-bearing performance even at low thickness.

Available Base Material

• PPGI (Prepainted Galvanized Steel Sheet)

• PPGL (Prepainted Galvalume Steel Sheet)

• GI Corrugated Sheet (for basic zinc protection)

• GL Corrugated Sheet (for improved aluminum-zinc resistance)

Key Features

• Excellent corrosion and weather resistance

• Vibrant and long-lasting colors

• Lightweight yet structurally strong
