Color Coated GI Sheet, also known as PPGI sheet or painted GI sheet, is a high-performance building material manufactured by applying a durable paint coating over a galvanized steel substrate. This process combines the superior corrosion resistance of galvanized iron (GI) with an attractive, long-lasting colored finish. At ChinaCNU Steel, with over 15 years of expertise, we produce premium color coated flat sheets ideal for modern architectural and industrial applications, exporting directly from our Qingdao factory to projects worldwide.

FAQ
What is the difference between GI sheet and PPGI sheet?
A GI sheet refers to Galvanized Iron sheet, which has a protective zinc coating. A PPGI sheet (Pre-Painted Galvanized Iron) is a GI sheet that has undergone an additional process where a colored paint coating (typically polyester, PVDF, or SMP) is applied on top of the zinc layer. This painted GI sheet offers enhanced aesthetics, additional protection against corrosion, and a wider range of colors for architectural applications.
What are the standard widths and coil weights for color coated flat sheet?
Standard widths for our color coated flat sheets typically range from 600mm to 1250mm. Coil weights can vary significantly based on thickness and width but generally range from 3 to 10 metric tons per coil. We can also provide sheets cut-to-length to your exact specifications to minimize on-site waste and labor.
How durable is the paint on color coated steel sheets for roofing?
The durability of the paint system on color coated steel sheets for roofing is excellent. We use high-quality polyester, PVDF, or SMP paints that offer strong resistance to UV fading, chalking, and weathering. The combination of the paint film and the underlying zinc coating provides a long service life, making it a cost-effective and low-maintenance solution for industrial and commercial roofing.
What is the typical lead time for exporting to the Middle East or Africa?
For standard specifications, our production lead time is 15-25 days from order confirmation. Shipping time to major ports in the Middle East or Africa varies but is typically an additional 20-35 days via sea freight. Our team manages the entire export process, including documentation and customs clearance support, to ensure smooth delivery to your specified port.
