Product details

Closed steel grating is one kind of steel grating with frame, also said with the closed end.

That means the length and the width of the steel grating can be produced according to customers' requirement. Such as 1mx1m,1mx2m,1mx3m,2mx3m and so on.

Steel bar grating is a good choice for strength, safety, long-term cost and durability. Bar Grating consists of a series of bearing bars, welded (or otherwise joined) at various intervals to perpendicular cross bars to form a load-bearing panel. It is available in a wide selection of panel sizes; bar sizes, and material types.
