180g/m² Pre Painted Corrugated Roofing Sheet Corrugated Metal Cladding

180g/m² Pre Painted Corrugated Roofing Sheet Corrugated Metal Cladding

1．Product Overview

180g/m² pre painted corrugated roofing sheet is used for roofing, corrugated metal cladding, wall panels, container plates, construction projects, home appliance panels, and industrial building applications.

The product is manufactured from galvanized or galvalume steel substrate with color coated surface. The corrugated profile improves panel rigidity, while the pre painted surface provides corrosion resistance and decorative appearance for roofing and cladding systems.

2．Technical Solution

The steel substrate can be supplied in DX51D, SGCC, SGCH, SGLCC, SGLCH, and Q195 grades according to project requirements.

Zinc coating range from 30g/m² to 275g/m² supports different corrosion resistance requirements. For this product, 180g/m² zinc coating is suitable for roofing and cladding applications requiring stronger anti-rust performance than lighter coating options.

The coating structure includes top side paint thickness of 15–25 microns and back side paint thickness of 5–15 microns. Normal coating design is top 17–25 microns and back 5–7 microns.
