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.

FAQ
What is the difference between GI and PPGI corrugated sheets?
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.
What zinc coating weight should I choose for my roofing project?
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.
Can you produce custom sizes and profiles?
Yes, as a direct factory, ChinaCNU Steel can customize the thickness, width, length, and corrugation profile (including specific designs like IBR profile galvanized) to meet your project’s architectural or engineering requirements. Please discuss your needs with our technical sales team.
How are the sheets packed for export shipping?
To prevent damage during transit, our galvanized corrugated steel sheets are packed in sturdy, moisture-resistant bundles. Standard packing includes steel straps for stability and waterproof wrapping. We can also provide customized packing solutions upon request to meet specific logistics or handling needs.
