Fiebrglass Grating - 1x4 Data Page

Centurion^TM Brand of MOLDED FIBERGLASS GRATING

1" x 4" x 1" Thick

(Rectangular Mesh)

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 below.

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
SPAN	LOAD (lb)
Inch	Normal	Firm
12	>3000	>3000
18	>3000	2288
24	2245	1496
36	849	535
48	497	320

Deflections less than 0.010" and greater than 0.500" have been omitted. The use of various resins, reinforcements and surfaces can result is variations of up to 15% in load data. Free span width for 48" span data is 2" less than width of grating.
