Heavy Duty Hot DIP Galvanized Steel Bar Grating
Steel grating, also known as bar grating or metal grating, is an open grid assembly of metal bars designed to hold heavy loads with minimal weight. The bearing bars run in one direction and are spaced by rigid attachment to crossbars running perpendicular to them. This versatile material is widely used as floors, mezzanines, stair treads, fencing, trench covers, and maintenance platforms in factories, workshops, motor rooms, trolley channels, heavy loading areas, boiler equipment, and heavy equipment areas.
