steel gratings Most-popular specifications

The grating that the pitch between bearing bars is 30mm, is most widely used type in industrial field. Among normal types, it has the strongest resistance to surface lash.

The grating that the pitch between bearing bar is 40mm is the most economical and lightest type. It is the best choice for you on occasions that the clear span is small.

The grating that the pitch between bearing bar is 60mm and the pitch between cross bars is 50mm is developed specially for mining industry. It solves the problem of mineral splash on the plate. So it is often appointed to use in processing works of mining industry.

The grating with the pitch of 30mm between bearing bars and of 76mm between cross bars is the most popular type used in home and abroad. It is proper for many applications such as walkways, platforms, etc.

We can also, as customers' request, manufacture other specifications of grating for fencing, gates and machine guards, etc.  bearing bars pitch can be set to n×30mm, n×40mm(n=1~5). Cross bars pitch can be set to n×100(n=1~5).

Manufacturing Process

Steel grating have been fabricated strictly in accordance to the product quality standards, and their high quality is guaranteed under the control of ISO9001 quality system. The manufacturing process charts are as follows:

Application area

Composite steel grating are widely used in cement mill, municipal engineering, sewage treatment plant, environmental sanitation engineering and many more other field. It is used for making cover spread platform, sidewalk, trestle stand, gutter cover, well lid etc. If welded riffled plate on the right side or under side , it can prevent small item drops. If we use composite steel grating in granary, restaurant, warehouse etc, it also can prevent small animal like mouse.
