Steel grating, also known as bar grating or metal grating, is an open grid assembly ofmetal bars, in which the bearing bars, running in one direction, are spaced by rigidattachment to cross bars running perpendicular to them or by bent connecting barsextending between them, which is designed to hold heavy loads with minimal weight. itis widely used as floors, mezzanines, stair treads, fencing, trench covers andmaintenance platforms in factories, workshops, motor rooms, trolley channels, heavyloading areas, boiler equipment and heavy equipment areas, etc.
