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

１．Product Overview

SGCC Galvalume Corrugated Roofing Sheet is designed for roofing and wall cladding systems in industrial, commercial, agricultural, and residential construction projects. Manufactured from hot dipped galvalume steel, the product combines lightweight performance, structural strength, and corrosion resistance for long-term outdoor service.

The corrugated profile improves load-bearing capability while maintaining low material weight, making it suitable for steel structure buildings, warehouses, workshops, and prefabricated construction.

２．Technical Solution

The base steel is coated with an aluminum-zinc alloy layer through a continuous hot-dip process. The coating forms a protective barrier against atmospheric corrosion while improving heat reflection performance compared with conventional galvanized roofing sheets.

The corrugated profile enhances stiffness and structural stability, allowing the sheet to span larger distances while maintaining dimensional integrity under wind and rain loads.

３．Specifications

４．Application

The product is widely used for industrial buildings, warehouses, workshops, agricultural facilities, steel structure housing, prefabricated buildings, roofing systems, wall cladding, equipment shelters, and storage facilities.

５．Processing

The sheets can be cut, drilled, screwed, riveted, and installed directly on steel or timber support structures. The passivated surface helps improve corrosion protection during transportation, storage, and installation.
