A service
grating walkway is provided to access the plant equipment. Grating panels consist of one
piece skid resistant steel plank, and is constructed of 18 gauge, galvanized sheet steel
with a maximum yield surface width of 37,000 PSI. Each grating panel has a standard 9-inch
surface width and a 2-1/2" rib depth. Each panel is supported to have a safe uniform
load carrying capacity of 80 pounds per square foot. The raised "NO-SKID" holes
are set in an open design that allows easy passage of air.
