Plain steel grating is one of most widely used steel grating. The bearing bar comes in the form of a plain surface flat bar. Commonly used for platforms trench grating and stair treads etc.
I bar steel grating in the form of an I-section. This type of grating is used where high strength is required and lightweights critical. Main types of bearing bar:
Serrated steel grating
The top of bearing bar is formed by a series of notches thus enhancing its not-slip characteristics. It is particularly suitable for use in slippery conditions such as oil refineries, tankers stairways, etc.
