Serrated Steel Grating

The excellent self-cleaning characteristics of plain surface grating make it suitable for the majority of applications. In the presence of fluids or materials that could cause the top surface of the grating to become wet or slippery, specification of the optional serrated surface should be considered. When serrated grating is specified, the bearing bar depth must be 1/4" greater than the sizes shown on the load tables to provide the equivalent strength of non-serrated gratings.
