Combined Steel Gratings
Combined steel gratings made of the steel grating which has spanning ability and the checkered plate which covers the surface. It can use any type of steel gratings and checkered plates of various thickness.Our improvement over the welding and galvanizing process has made it possible to successfully galvanize steel grating and checkered plate as a whole after welding them by unit, without any deform after galvanization. This has ensured the safety of galvanizing coat from being spoiled.

Designed and manufactured with pressure welded steel grating,and widely used in the industrial and civil constructions,such as urban road,square,botanical garden,wharf,airport,parking lot,highway,and industrial engineering. |
SFD Brand 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.The bearing bars (flat steel), running in one direction signifying the length of the gratings, are spaced by rigid attachment to cross rods(square steel) running perpendicular to the bearing bars representing the width.Strong welding points are thus secured.
FSD Brand Steel Bar Gratings are classified into two 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.
