Electroforged Steel Gratings are made using the electroforging process. In this process, the sqaure twisted rods (Cross Members) are fused into the main load bearing members at using a special welding machine at very high current and tonnage. The Cross Members are properly set-in the Load Members such that it projects out of the grating top member by only a little more than 1 mm. This improves the slip resistance during walking. Electroforged Grating Panels are generally manufactured to 6000 mm lengths.
The panels are then cut to exact Spans as per the customer requirements. The cut panels are then taken for welding of the Banding Bar. Notches and Toe Plates are added as required as per the drawing requirements.
The gratings are then Hot Dip Galvanized.
