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.
