* Pounds per square foot (All weights are approximate).

** Item numbers for the GW and SGW series are created by adding additional numbers and letters to the series for each bearing bar size. For example, a GW-2 grating with a bearing bar size of 1–1/4 by 1/8 inch is a GW-125A-2.

For stainless steel, the standard mill finish will be gray and will have a discoloration of various colors (blue, black, brown, etc.) as a result of the heat generated in the welding process in manufacturing of the grating. Sandblasting available for stainless steel.
