Generally steel grating, also known as bar grating or metal grating, is an open grid
assembly of metal bars, in which the bearing bars, running in one direction, are spaced
by rigid attachment to cross bars running perpendicular to them or by bent connecting
bars extending between them, which is designed to hold heavy loads with minimal
weight. It 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, etc
