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

To convert inches to metric, use the conversion calculator.

* Typically, your selection, for a given load and span, should fall within the shaded areas. Spans in shaded areas 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 discretion of the engineer.

** The specifier is responsible for verifying conformance of this product with applicable codes associated with its intended use.

Aluminum grating is typically supplied as mill finish and is treated with a caustic cleaner after fabrication.

The carrying capacity of a piece of grating subjected to a concentrated load over only a portion of its width is determined by the stiffness of both the bearing bars and the cross bars, and therefore varies with the type of grating used. To determine carrying capacity of gratings subject to such loadings, please call McNICHOLS (800-237-3820).
