MOLDED GRATING LOAD AND DEFLECTION DATA
The designer should not exceed MAXIMUM-RECOMMENDED load at any time. MAXIMUM LOAD represents a 3:1 factor of safety on ULTIMATE CAPACITY. ULTIMATE CAPACITY represents MAX LOAD observed at initial fracture.
Walking loads for maintenance traffic are typically a live load of 60 PSF. Deflections for worker comfort aretypically limited to 3/8 " or SPAN divided by 120 under full live load. For a firmer feel under full live load or a line load 250 lbs/ft of width, limit deflections to 1/4 " or SPAN divided by 200.
The loads represented are for STATIC LOAD CONDDITIONS at ambient temperature. Deflections for impact loads or dynamic loads will MULTIPLY the deflections shown by 2. Long term loads will result in added deflection due to creep in the material and will require higher factors of safety to ensure acceptable performance.
