Gi Grating

GI (galvanized iron) grating specifications include material standards (like IS 2062), dimensions (bearing bar size, cross bar size, and spacing), manufacturing methods (electroforged, press-locked), and finishing requirements (hot-dip galvanizing as per IS 2629 or IS 4759). Common dimensions for bearing bars are \(30\times 5\) mm and for cross bars are \(8\) mm, with a mesh size of \(40\) mm between bearing bars, though these can vary depending on the application.Material and manufacturingMaterial: Galvanized steel, conforming to standards like IS 2062 for bearing bars and IS 1786 for twisted bars.Manufacturing Process: Electroforged, press-welded, or press-locked. Welding is typically done between the bearing bars and the edge bars, and all cross bars are press-locked into the bearing bars.Surface Treatment: Hot-dip galvanizing is a common finish, with zinc coating applied as per standards like IS 2629 or IS 4759.
