0.55mm SGCC PPGI Steel Coil with PE Coating for Roofing and Building Panels
0.55mm SGCC PPGI Steel Coil with PE Coating for Roofing and Building Panels
１．Product Overview
0.55mm SGCC PPGI Steel Coil is a pre-painted galvanized steel coil designed for roofing panels, building cladding, furniture components, vehicle parts, and industrial fabrication. The product combines a galvanized substrate with a PE paint system to provide surface protection, appearance consistency, and processing efficiency.
The pre-painted finish reduces secondary painting requirements and supports roll forming, bending, profiling, and panel manufacturing operations.
２．Technical Solution
The product uses SGCC galvanized steel substrate with a zinc coating of 40g/m². The coating system consists of 15 Micron Polyester + 5 Micron Primer on the top surface and 7 Micron + 5 Micron Primer on the reverse side.
The PE coating system provides decorative appearance, surface durability, and protection against normal atmospheric exposure. The galvanized substrate supplies basic corrosion resistance while maintaining formability for roofing and construction applications.
