Notes
 
* BB = Bearing Bar

See the load tables for bearing bar heights and the respective load and deflection data.

Use the Conversion Calculator to convert inches to metric.

Available with a serrated surface by special order (reduced loading applies, see load table).

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