GI (Galvanized Iron) Plain Sheet refers to a flat steel sheet with a zinc coating but no colored paint layer, offering basic corrosion protection. PPGI (Pre-Painted Galvanized Iron) Sheet is a galvanized plain sheet that has undergone an additional process to apply a colored paint or polyester coating on top of the zinc, providing both corrosion resistance and an aesthetic finish. Choosing between them depends on whether you need durable corrosion protection for hidden structures or a finished colored panel for visible architectural cladding.
To maintain the corrosion protection of your flat GI sheet, it is recommended to use fine-tooth saw blades, nibblers, or plasma cutting. After cutting, the exposed edges should be treated with a zinc-rich paint to restore the protective barrier and prevent rust, ensuring the long-term durability of cut galvanized steel panels.
Yes, we can produce GI Plain Sheets with both regular spangle and minimal spangle finishes based on your request. The spangle pattern is a visual crystallization of the zinc coating. A minimal spangle finish provides a more uniform, smoother appearance, which is often preferred for subsequent painting or applications where a consistent look is important for visible galvanized steel sheet applications.
