SlipNOT® aluminum plank grating provides a strong, lightweight flooring alternative to bar grating and fiberglass. Punched aluminum with a SlipNOT® coating allows light and liquids to drain through, like bar grating, but provides the additional surface coverage and slip resistance needed to prevent slip and fall accidents from occurring. The flush top of punched plank provides maximum foot contact and the same strength-to-weight ratio as bar grating. Punched aluminum has internal rigivity due to the extruded aluminum manufacturing process, and makes it less suseptible to damage.
