1.5" Thick CC-Grate
1.5" x 6" (Rectangular Mesh)

Point Load: Reflects the deflection achieved by concentrated point load applied at the center of a grating panel of varying spans. Maximum loads for "Normal" or "Firm" support under this loading are indicated.

Uniform Load (Full Panel): Reflects the deflection achieved with loads distributed evenly across 12-foot long grating pieces of varying spans.

POINT LOAD (center of panel)			"Normal" is the load (in pounds) that will produce a deflection of 0.375" (accepted as providing a "Normal" feel for foot traffic). "Firm" is the load (in pounds) that will produce a deflection of 0.250" (accepted as providing a "Firm" feel for foot traffic). All deflections are presented in inches. Loads are presented in pounds

INSTALLATION NOTES: The following tables have been developed based on two sided support layouts. Caution is needed to be sure that the rectangular grating is installed with bearing bars running from support to support. All grating should be fastened to the supports using fasteners such as the CC-Clips described in this site. These should be used every 3’-4’ along the supports, with a minimum of four clips on small sections. The clips not only add safety for the employees using the grating, but also improve on the deflection noted.

Concentrated Load (12" Strip): Reflects the deflection achieved using a 12-inch wide strip of grating tested at the mid-point of varying spans.
