* Method I: Load was applied via a 2.925" diameter x 3" long steel rod placed on the center distributing
the load through the face of the steel rod. Test was performed in respective channels and basins to simulate
field conditions.
** Method II: Load was applied via an 8" diameter x .30" thick aluminum plate. Specimen was tested in a
9.5" x 14" support frame made from 2" x 6" wood studs.
Example: The 3" Channel 500 series is capable of withstanding a direct static loading force of at least
206 PSI. Assuming a typical passenger car or light truck tire bearing upon a gross contact area of 48 square
inches, this grate could theoretically support a static single wheel load of 9,888 lbs. in compression only.
