0.5mm DX51D AZ275 Galvalume Corrugated Roofing Sheet with 800mm Effective Width for Steel Structure Buildings

１．Product Overview

DX51D AZ275 Galvalume Corrugated Roofing Sheet is manufactured from aluminum-zinc coated steel and designed for roofing and wall cladding applications. The corrugated profile increases structural rigidity while maintaining lightweight characteristics, making it suitable for steel structure buildings, warehouses, workshops, and prefabricated housing projects.

The aluminum-zinc coating provides improved corrosion resistance and heat reflectivity, supporting long-term outdoor performance in a wide range of environments.

２．Technical Solution

The steel substrate is coated with an aluminum-zinc alloy through a continuous hot-dip process. This coating combines the barrier protection of aluminum with the sacrificial protection of zinc, helping to reduce corrosion over extended service periods.

The corrugated profile enhances load distribution and mechanical strength, allowing the sheet to withstand wind loads, rain exposure, and daily environmental conditions commonly found in construction projects.

３．Specifications

４．Application
