Description              

Steel Grating are manufactured with the pressure resistance welding machine by electro-forging the twisted square-steel into flat steel. The bearing bars running in one direction signifying the length of the gratings, are spaced by rigid attachment to cross rods running prependicular to the bearing bars representing the width. Strong welding points are thus secured.

Steel grating are classified into two styles namely plain style and serrated style as per the upper edges of bearing bars. More than 200 varieties are avaliable based on specificatins and spacing of bearing bars, and that of cross rods.
