Heavy duty fiberglass grating is engineered to carry higher loads that traditional fiberglass grating products are unable to support. It is available in both molded and pultruded grating systems.

 

Capitalizing on most of the traditional benefits of fiberglass grating products, heavy duty fiberglass grating is specifically designed for applications where heavy loads (such as fork truck traffic) at very long spans are required in corrosive environments. This highly engineered product is usually used to replac heavy steel gratings which is prone to bending and breaking under heavy loads.

 

One piece of heavy duty fiberglass grating is displayed.

HDFG-01: Heavy duty fiberglass grating in dark gray, which is the most common used colour.One piece of heavy duty fiberglass grating is installed above the drainage hole and one fork truck wheel is on it.

HDFG-02: Gray heavy duty fiberglass grating for applications where heavy loads are required in corrosive environment.

One piece of pultruded high load capacity fiberglass grating in dark gray.
