１．Product Overview

AZ180 DX51D Galvalume Corrugated Roofing Sheet is manufactured from aluminum-zinc coated steel and formed into a corrugated profile for roofing and wall cladding applications. The AZ180 coating provides enhanced corrosion resistance, while the regular spangle finish delivers a traditional metallic appearance. It is widely used in civil buildings, industrial facilities, warehouses, and prefabricated construction projects.

２．Technical Solution

The sheet is produced using cold-rolled steel substrate coated with an aluminum-zinc alloy layer. The coating combines approximately 55% aluminum, 43.5% zinc, and 1.5% silicon to provide barrier protection and sacrificial corrosion resistance. Corrugation increases structural rigidity and improves load-bearing performance while maintaining lightweight characteristics.

３．Specifications

４．Application

Suitable for civil buildings, residential housing, warehouses, workshops, agricultural facilities, storage buildings, commercial roofing systems, wall cladding, fencing structures, and prefabricated building projects.

５．Processing

The sheets can be cut to length, drilled, fastened, and installed using standard roofing accessories. Corrugated profiles allow efficient water drainage and improved structural strength. Proper overlap installation enhances weather resistance and service life.
