0.14mm-1.5mm Regular Spangle Galvanized Corrugated Steel Roofing And Wall Panels

0.14mm-1.5mm Regular Spangle Galvanized Corrugated Steel Roofing And Wall Panels

１．Product Overview

Regular spangle galvanized corrugated steel roofing panels are manufactured from hot dipped galvanized steel for roofing, wall cladding, and sandwich panel systems. The corrugated structure improves rigidity and load-bearing performance while maintaining lightweight construction characteristics for industrial and commercial projects.

Produced according to JIS G3302 standard, the product is available in SGCC, DX51D+Z, and SGLC materials with zinc coating from 30g/m² to 275g/m². The sheets provide stable corrosion resistance, weather durability, and efficient installation performance.

２．Technical Solution

The corrugated roofing sheets are produced through hot dipped galvanizing and precision roll forming processing. The galvanized zinc coating forms a protective barrier against atmospheric corrosion and improves outdoor durability.

The corrugated wave structure increases bending strength and roofing stability while supporting effective water drainage. Regular spangle surface finish provides a traditional galvanized appearance suitable for industrial and structural applications.

３．Specifications

４．Application

The galvanized corrugated roofing sheets are widely used in industrial buildings, warehouses, steel structure workshops, agricultural buildings, sandwich panel systems, roofing systems, wall cladding systems, and prefabricated construction projects.

The product is suitable for large-span steel structures requiring lightweight roofing materials with stable corrosion resistance.

５．Processing

The product is manufactured from galvanized steel coils through corrugated roll forming processing. Sheets can be supplied in customized lengths according to project installation requirements.

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

６．Advantages

• Stable corrosion resistance with galvanized zinc coating
• Lightweight structure for easy installation
• Regular spangle galvanized surface appearance
• Good rigidity and drainage performance
• Suitable for roofing and wall cladding systems
• Available in multiple thickness and coating options
• Compatible with sandwich panel applications
• Reliable dimensional consistency

７．How to Choose

Select zinc coating according to service environment:

• 30-80g/m² for indoor or dry environment applications
• 100-180g/m² for general outdoor construction
• 200-275g/m² for coastal or high humidity conditions

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

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