GI Decking Sheets (Galvanized Iron Decking Sheets) are corrugated metal sheets made of galvanized steel, primarily used in the construction of floors, roofs, and walls in buildings. They are especially popular in steel-framed buildings, where they serve as both a structural element and a formwork for concrete slabs. GI decking sheets are known for their strength, durability, and versatility, offering a cost-effective and efficient solution for construction projects.
