Flat/smooth type steel bar grating
Product description
Flat 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, mezzanine, 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.
It is one of the most popular and versatile industrial steel gratings. It provides excellent bearing capacity and is widely used in almost all industrial applications.
