Serrated steel grating is the most popular of all grating typesdue to its strength, cost-efficient production and ease ofinstallation. In addition to its high strength and light weight,this type of grating also has non-slip characteristics, nosharp edges and serrations are rolled on, to meet stricthealth and safety requirements. Hot rolled serrations helpstop lacerations if someone falls on the grating.
Optional serrated bearing bars enhance skid resistance.Consider this surface for applications subject to theaccumulation of liquids or lubricants or inclined gratinginstallations. The excellent self-cleaning characteristics ofplain surface grating make it suitable for the majority ofapplications.In the presence of fluids or materials that couldcause the top surface of the grating to become wet orslippery, specification of the optional serrated surface shouldbe considered. When serrated grating is specified, thebearing bar depth must be 1/4" greater, to provide theequivalent strength of non-serrated gratings.
