Galvanized corrugated sheet is building material composed of sheets of hot-dip galvanised mild steel, cold-rolled to produce a linear corrugated pattern in them. The corrugations increase the bending strength of the sheet in the direction perpendicular to the corrugations, but not parallel to them. Normally each sheet is manufactured longer in its strong direction. Galvanized corrugated sheet is lightweight and easily transported. It was and still is widely used especially in rural and military buildings such as sheds and water tanks.
GC sheets prove to be a cost effective solution for various construction purposes such as roofing, side-walls, partitions and panels.
Corrugated Galvanized sheets are mainly used for roofing purpose.
Corrugated galvanized sheets are generally termed as G.C. Sheet.
