Galvanized Corrugated Sheet is a durable and versatile steel building material, widely used for roofing, cladding, and structural applications. This product consists of a steel sheet that has been hot-dip coated with a layer of zinc, providing superior corrosion resistance, and then formed into a distinctive corrugated profile for added strength and rigidity. At ChinaCNU Steel, with over 15 years of manufacturing expertise in Qingdao, China, we produce high-quality GI corrugated sheets designed for longevity and performance in diverse climates and industrial settings, exporting to projects worldwide.
Our Galvanized Corrugated Sheets are manufactured to exacting standards, available in various profiles including the popular IBR profile galvanized. Below are the standard specifications we offer, with custom dimensions and coatings available upon request.
| Grade | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Standard |
|---|---|---|---|---|
| DX51D, DX52D, SGCC | 0.12 – 1.2 | 600 – 1250 | 60 – 275 (Z60 – Z275) | ASTM A653, JIS G3302, EN 10346 |
| Q195, Q235 | 0.3 – 3.0 | 1000 – 1250 | 80 – 220 | GB/T 2518 |
The strength, weather resistance, and cost-effectiveness of zinc corrugated roofing make it ideal for a wide range of commercial, industrial, and agricultural projects. Key applications include:

GI (Galvanized Iron) corrugated sheets have a protective zinc coating, offering excellent corrosion resistance. PPGI (Pre-Painted Galvanized Iron) sheets are GI sheets with an additional colored paint coating (polyester, PVDF, etc.) on top, providing extra durability, aesthetic appeal, and specific performance properties like UV resistance. For standard zinc corrugated roofing, GI is typically used.
The ideal zinc coating (e.g., Z120, Z180, Z275) depends on the environmental conditions. For interior or mild environments, Z60-Z120 may suffice. For coastal areas or industrial atmospheres with higher corrosion risk, we recommend Z180 or higher for your galvanized steel roofing sheets to ensure a longer service life.
