AS 1397 G550 ASTM A653 Galvanized Corrugated Roofing Sheets With SGCH Regular Spangle

１．Product Overview

AS 1397 G550 ASTM A653 galvanized corrugated roofing sheets are manufactured from hot dipped galvanized steel with regular spangle surface finish for roofing and wall cladding applications. The corrugated profile improves structural rigidity while maintaining lightweight construction performance for industrial, commercial, and residential projects.

Produced according to JIS G3302, ASTM A653, and AS 1397 standards, the sheets provide stable corrosion resistance, weather durability, and installation efficiency. SGCH full hard material is suitable for roofing systems requiring higher hardness and structural strength.

２．Technical Solution

The roofing sheets are produced through hot dipped galvanizing and precision roll forming technology. The galvanized zinc coating provides corrosion protection against moisture and outdoor exposure, while the corrugated wave design improves bending strength and drainage performance.

The 76mm wave width and 17mm-17.5mm wave height provide reliable overlap installation and roofing stability. SGCH full hard steel improves rigidity and reduces deformation during transportation and installation.

３．Specifications

４．Application

The galvanized corrugated roofing sheets are widely used in industrial buildings, warehouses, steel structure workshops, logistics centers, airports, train stations, commercial buildings, supermarkets, prefabricated houses, and agricultural construction.

The sheets are suitable for roofing systems, wall cladding systems, ceilings, fences, and container structure applications.

５．Processing

The product is manufactured from hot dipped galvanized steel coils through corrugation forming processing. Sheets can be supplied in customized lengths and widths according to project requirements.

Standard seaworthy export packing is used to improve transportation safety and reduce moisture exposure during shipment and storage.

６．Advantages

• High strength SGCH full hard material
• Stable corrosion resistance with 60-275g/m² zinc coating
• Lightweight structure for fast installation
• Regular spangle galvanized surface appearance
• Good waterproof and drainage performance
• Suitable for roofing and wall cladding systems
• Customizable sizes for construction projects
• Reliable dimensional consistency for overlap installation

７．How to Choose

Select zinc coating according to the service environment:

• 60-100g/m² for indoor or dry climate applications
• 120-180g/m² for general construction projects
• 200-275g/m² for coastal or high humidity environments

Choose thicker material for long-span roofing systems and areas requiring higher load-bearing capability.

Confirm effective width and overlap requirements before installation to reduce material waste and improve construction efficiency.
