The composition of the bearing bars have a full height span direction while the transverse bars (known as control bars) have a reduced depth in height. This design ensures maximum strength to weight ratio. Where anti-slip qualities are needed, the bars can be serrated in one or both directions.

These gratings are available in a variety of mesh sizes (apertures) and are suitable for a variety of applications such as industrial, domestic, public and vehicular. This design can be fitted upside down to provide a linear look if desired.
