Product Description
THE POPULAR SPECIFICATIONS OF STEEL GRATING
The grating with a pitch of 30mm between bearing bars is the most widely used type in the industrial field. Among normal types, it has the strongest resistance to surface lash.
The grating with a pitch of 40mm between bearing bars is the most economical and lightest type. lt is the best choice for you on occasions when the span is small.
The grating with a pitch of 60mm between the bearing bars and a pitch of 50mm between the cross bars is developed especially for the mining industry, it solved the problem of a mineral splash on the plate. So it is often appointed for use in processing works of the mining industry.
The grating with a pitch of 30mm between bearing bars and of76mm between cross bars is the most popular type used at home and abroad, it is proper for many applications such as walkways, platforms, etc.
