Walkway gratingis has a widespread application, and has been a stalwart per former of long standing in practically allkinds of commercial and industrial settings. It has found countless applications in catwalks, platforms and mezzanines.Walkway grating is machine manufactured by the electro-forge process, where crossbars are welded to bearing bars through the simultaneous application of an electric current and hydraulic pressure. It is designedto support pedestrian and light static loads. Walkway grating designations are the same as those used for Heavy-Duty Grating, and like heavy-duty grating, can be supplied either smooth or serrated. Bar sizes aremuch lighter than heavy-duty grating, rangingfrom 3/4 x 1/8 to 2-1/2 x 3/16, and designis based on application of uniform and concentrated loads. Maximum safe spans are shown in the accompanying tables. A significant application for walkway grating is stair treads.
