Zinc Coating 40–275g/m² Galvanized Corrugated Roofing Sheet with Regular Zero Big Spangle

１．Product Overview

Galvanized corrugated roofing sheet is made from galvanized steel and roll formed into a corrugated zigzag profile for roofing and building envelope applications.

The galvanized surface provides corrosion resistance, while the corrugated profile improves sheet rigidity and installation stability. With 0.13–1.5mm thickness, 600–1250mm width, and 40–275g/m² zinc coating, the product is suitable for roofing sheets, wall cladding, partition walls, ceilings, and general construction use.

２．Technical Solution

The product combines galvanized steel substrate with corrugated roll forming. The zinc coating acts as a protective layer against oxidation and rust, helping improve durability in outdoor and industrial environments.

Regular, zero, and big spangle surface options are available for different appearance requirements. Customized length, width, thickness, zinc coating, and packaging can be supplied according to project needs.
