Safetread diamond pattern flooring is constructed using a series of flat load bearing bars held upright by corrugated bars. The load bearing bars and corrugated bars are spot welded together at each intersection point making safetread diamond pattern flooring universally accepted as one of the strongest and most economical open steel gratings.

Corrugated bars not only contribute to the load bearing capabilities of the grating but also provide the grating with increased lateral restraint making it one of the most popular steel grating solutions that we offer at Lionweld Kennedy. This is why Saferead has been installed in the largest of power stations, steelworks, chemical plants and distilleries and a host of other industrial and civil undertakings where strength, cleanliness, light and ventilation are essential factors.
