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

** Item numbers for the GCM series are created by adding additional numbers and letters to the series for each bearing bar size. For example, a GCM-3 grating with a bearing bar size of 1 by 1/8 inch is a GCM-3-100A.

Aluminum grating is typically supplied as mill finish and is treated with a caustic cleaner after fabrication.

Use the Conversion Calculator to convert inches to metric.
