Notes:
U - Uniform load, pounds per square foot

D - Deflection in inches resulting from the Uniform Load

C - Concentrated load, lb/foot grating width

D - Deflection in inches resulting from the Concentrated Load

* - Spans in shaded area produce a deflection of 1/4 inch or less for a uniform load of 100 pounds per square foot.This deflection is recommended to provide comfortable safety margins, but may be exceeded at the descretion of the engineer.

** - Loads and deflections given in this table are theoretical and are based on a tensile bending stress of 19,000 PSI. The specifier is responsible for verifying conformance of this product with applicable codes associated with its intended use. Meets Federal Spec. RRG-1602C.
