Bar grating
Platform steel grating: According to the different types of the bar, steel grating is mainly divided into the following three categories, their respective features are as follows:
1
.plain style: plain steel grating is the most popular type. It is mainly used for platforms, walkways, drainage pit cover, stair tread etc.
2
. serrated style: Its slip resistance is better than the plain style.
3
. I-bar: I-bar steel grating with the light weight, more economical and practical features than the plain style.

The common specification:
1
.The type of steel grating which pitch of bars is 30mm is used most widely for all sectors of industry. It has the greatest resistance to surface impact.
2
.The type of steel grating which pitch of bars is 40mm is widely used in the industry field too. For the suitable interval of the bars so it always economical and weight-lightest.
3
.The type of steel grating which with pitch of bars is 60mm, cross bars pitch 50mm has been developed specially for mining industry and weight-lightest in all grating. In case of short spans they can meet a variety of uses.
