Product Description

Product Description

 

Hot DIP Galvanized Trench Cover 

    Hot dipped galvanized trench cover, 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.
