Compound Steel Bar Grating

It is a product consisting of steel bar grating, which is capable of horizontal lengthening, and surface sealed figure plate.
The steel bar grating can be any specification and the thickness of the figure plate can be different. The common bar grating is Q323/40/100 and figure plate is 3mm thick or 4mm, 5mm and 6mm.
The way of fixing can be either welded or fixed with clamps. The way of welding can make the item fixed permanently and never get loose. It is done at every corner of the bar grating . Welded joint: length>=20m Height >=3mm
Nonetheless the clamps won't damage the galvanized layer and is easy to uninstall. At least 4 sets of clamps are required for each plate. The best way is not to use down clamps and the head of the screw is welded on the beam so that the bar grating won't drop from the beam as for the loosening of the clamps.
