１．Product Overview

AS 1397 G550 galvanized corrugated roofing sheet is designed for roofing and wall cladding applications that require high strength, corrosion resistance, and stable profile performance.

The product is manufactured from hot dipped galvanized steel and formed into a corrugated roofing profile. Full hard grades such as G550 and JIS G3302 SGCH provide higher rigidity for construction roofing systems, steel structure buildings, warehouses, workshops, and public facilities.

２．Technical Solution

The galvanized steel substrate provides zinc coating protection against oxidation and corrosion, while the corrugated profile improves sheet stiffness and installation stability.

AS 1397 G550, ASTM A653, and JIS G3302 grades can be selected according to project requirements. Zinc coating from 40–275g/m² supports different outdoor exposure conditions, while big, small, and zero spangle options meet different surface appearance requirements.

３．Specifications

４．Application

Galvanized corrugated roofing sheets are widely used in power plants, electrical equipment workshops, car showrooms, steel plants, cement warehouses, steel structure offices, airport terminals, train stations, stadiums, concert halls, theaters, supermarkets, logistics centers, and other

roofing and wall system projects.

５．Processing

The product can be supplied with customized length, width, zinc coating, hardness, and spangle type according to project requirements.

Corrugation forming, cutting, bundling, seaworthy packing, and export shipment can be arranged according to order specifications.

６．Advantages

• AS 1397 G550 full hard grade for high sheet rigidity
• ASTM A653 and JIS G3302 standard options available
• 40–275g/m² zinc coating for corrosion protection
• 0.15–1.5mm thickness range for different roofing requirements
• Big, small, and zero spangle surface options
• 76mm wave width and 17–17.5mm wave height for stable roofing profile
