FRP Grating Load Tables

How much Weight with FRP Grating Support?

Our FRP Load tables show you how much deflection you can expect for various spans. The load tables show the deflection for both concentrated and uniform loads. The greater the distance between supports (span), the more deflection your will have for any given weight.

Molded FRP grating is used in all kinds of applications where a strong, lightweight deck or walkway is require that will not rust. You typically see molded grating in corrosive environments such as chemical plants, pulp mills, and waste-water treatment plants.

As you can see from the load tables, molded grating can easily support a person walking - even a big guy, as long as you have the required span between your supports.

If your supports are 18" on center, 1" molded grating will have a deflection of 0.123" for a 300 lb uniform load and 0.131" for a 300 lb concentrated load. Most of our customers can live with this amount of deflection.

When your span gets up to 30", you may wish to consider going to the stronger 1.5" deep grating. 1.5" molded grating will have a deflection of 0.283" for a 300 lb uniform load and 0.181" for a 300 lb concentrated load.
