The compound steel bar grating is a perfect combination of steel bar grating and checkered plate, featuring beautiful appearance and high solidity. When it comes to the manufacture of compound steel bar grating, JG323/40/100, JG253/30/100 and JG323/40/100 steel bar grating are most often used as the base plate. Then, weld 3mm thick checkered plate upon the base plate. After proper polishing and surface treatment, a good condition compound steel bar grating is produced. In consideration of different working conditions, the dimensions and materials of grating and checkered plate can be customized.
Notes: After the hot-dip galvanization, the compound steel bar grating is easy to warp and deform because of thermal expansion and the adjusting and correcting work is also hard, especially for large-scale steel bar grating. Thus, we recommend small-scale gratings.
