As a leading GI coil manufacturer in China, ChinaCNU Steel provides factory-direct, high-quality galvanized iron coil solutions for global industrial projects. A GI steel coil, or galvanized iron coil, is a cold-rolled steel coil that has been coated with a layer of zinc through a continuous hot-dip galvanizing process. This protective coating provides superior corrosion resistance, extending the lifespan of the steel and making it a cost-effective and durable material for construction, manufacturing, and various engineering applications. With over 15 years of expertise exporting from our Qingdao factory, we ensure reliable supply, consistent quality, and competitive pricing for buyers worldwide.
Our galvanized iron coils are produced to meet international standards and can be customized to your project requirements. Below are our standard specifications.

GI coil refers to galvanized iron coil, which has a zinc coating for corrosion protection. PPGI coil, or pre-painted galvanized iron coil, is a GI coil that has undergone a further process where a colored paint or laminate is applied over the zinc layer. This adds aesthetic appeal and additional environmental resistance, making it ideal for architectural applications where both durability and specific color matching are required.
For safe international shipping, our standard export packing for factory direct GI coil from Qingdao includes wrapping the coil in waterproof paper, followed by a protective steel wrapper or sleeve. The coil is then securely mounted on a wooden pallet or placed in a sturdy steel crate to prevent movement and damage during transit. We can customize packing upon request to meet specific logistics requirements.

While we offer a wide range of standard thicknesses and widths, we can produce galvanized iron coils in non-standard dimensions based on your technical drawings and project specifications.
