Steel Bar Gratings are manufactured with the world’s first-class computer- controlled
pressure resistance welding machine by electro-forging the twisted square-steel into flat steel.Steel Bar Gratings are classified into three styles,namely plain style,serrated and I style as per the upper edges of bearing bars .More than 200 varieties are available based on specifications and spacing of bearing bars ,and that of cross roda.Different protective treatment can be made on the surface as environment varies.
