Galvanized Corrugated Metal Roofing Sheets 0.14–1.50mm with 30–275g/m² Zinc Coating for Roofing and Wall Panels

1．Product Overview

Galvanized corrugated metal roofing sheets are used for roofing, wall cladding, warehouse buildings, workshops, agricultural buildings, and light steel structure projects.

The product is made from hot dipped galvanized steel and formed into a corrugated profile. The zinc coating provides corrosion protection, while the corrugated shape improves sheet rigidity and drainage performance for roofing applications.

2．Technical Solution

The galvanized steel sheet is roll formed into a corrugated profile with a standard wave width of 76mm and wave height of 17–17.5mm.

The zinc coating range of 30–275g/m² supports different project environments, from standard roofing use to applications requiring stronger corrosion protection.

Available spangle options include regular, big, small, and zero spangle to match different appearance and project requirements.
