For durable and cost-effective roofing solutions, the GI Corrugated Roofing Sheet is a premier choice for industrial, agricultural, and residential projects worldwide. This product is a hot-dip galvanized steel sheet formed into a classic corrugated profile, providing exceptional strength, weather resistance, and longevity. The zinc coating protects the base steel from corrosion, making these galvanized corrugated sheets ideal for harsh climates. At ChinaCNU Steel, with over 15 years of expertise, we export high-quality GI roof sheets directly from our Qingdao factory to over 50 countries, offering competitive GI roof sheet price points and reliable supply for major markets like Africa, the Middle East, and Southeast Asia.
Our GI Corrugated Roofing Sheets are manufactured to precise standards, ensuring consistent quality and performance for your construction needs. Below are the detailed specifications.
| Grade | Thickness (mm) | Width (mm) | Zinc Coating (g/m²) | Standard |
|---|---|---|---|---|
| DX51D, SGCC | 0.12 – 0.70 | 600 – 1250 | 60 – 275 | ASTM A653, JIS G3302, EN 10346 |
| Q195, Q235 | 0.15 – 0.80 | 750 – 1200 | 80 – 180 | GB/T 2518 |
The versatility of galvanized corrugated sheet makes it suitable for a wide range of structural and cladding applications across multiple sectors.

The lifespan of a galvanized corrugated sheet in coastal, high-salinity environments depends heavily on the zinc coating weight. Sheets with a heavier coating (e.g., 180 g/m² or higher) can last 20-30 years with proper installation, as the zinc provides sacrificial protection against salt-induced corrosion, making it a preferred material for long-term zinc roofing Africa projects.
Yes, GI sheets can be painted after a proper surface preparation process to ensure paint adhesion. For a pre-finished option, you may consider our PPGI (Pre-Painted Galvanized Iron) sheets, which come with a durable color coating applied at the factory, offering enhanced aesthetics and additional protection against weathering.
For regions with heavy rainfall and high humidity, we recommend a medium to high zinc coating between 120 g/m² and 180 g/m². This ensures a robust barrier against constant moisture, preventing rust and extending the roof’s service life, which is a crucial consideration for durable galvanized corrugated sheet installations.
To calculate the quantity, you need the total roof area and the effective covering width of the sheet (which is less than the total width due to side laps). Our technical team can assist you with this calculation. Providing your roof dimensions allows us to give you an accurate material estimate and the most efficient GI roof sheet price for your total project volume.
