7.There are three kinds of steel gratings distinguished by different bearing bar types.

The respective of features are as follows:

Plain:One of the most widely used gratings,available for flooring,sidewalk,dranage pit cover,stair tread,etc.Serrated:Better non-skid property & safety compared with plain grating.I-Shape:lighter,more economical and practical compared with plain grating.

We have our own AutoCAD designing team, and specialize in supplying cut-to-size steel gratings to projects.
