The fiberglass load and deflection tables included on this website provide uniform load and concentrated loads of regular capacity fiberglass grating.

‘Maximum Load Recommended’ represents levels below which corrosion resistance damage does not occur.

Ultimate Load Capacity represents a complete and total failure of the grating and is presented to illustrate the reserve strength of the grating at a given span, these amounts represent the lowest or most conservative ultimate capacity value.

‘Ultimate capacities’ are not to be used for design, functionality of the grating is limited to the ‘Maximum Recommended Load’.

The load/deflection values provided in the tables are average values with manufacturing control limits on stiffness for all panels plus or minus 7.5% of these average values.

Uniform Load - lbs/sq ft

Concentrated Load - lbs/ft of width
