Heavy Duty Welded Steel Grating is by far the most popular choice where heavy static or rolling loads are encountered. The bearing bars for our Heavy Duty Welded Steel Grating (W Series) are available in 5 different spacings (15, 19, 22, 30 and 38-Space), 4 bearing bar thicknesses, and various depths ranging from 1" to 6". Galvanizing is an option and stainless steel can also be provided for highly corrosive applications. Serrated surface is optional and SlipNOT® slip resistance coating is also available. Not all grating sizes available in stainless steel (check size availability with PMWI prior to ordering).
