The through-drilled steel grating typically features holes at the mid-height of the bearing bars, through which round cross bars are inserted and securely welded to the load-bearing flat steels.
This type of grating is often utilized in heavy-duty steel gratings. Compared with ordinary welded steel gratings, the surface of the through-drilled steel grating is smoother.
