Duradek high strength fiberglass grating is a pultruded bar type grating that can be designed and used like traditional metal grates. The individual bearing bars are either 1" or 1-1/2" "I" shapes or a 2" "T" shape.

Duradek is also a flame retardant product utilizing a premium grade vinyl ester resin. The bearing bars use both longitudinal (glass roving) and multidirectional (glass mat) reinforcements as well as a synthetic surfacing veil to provide unequaled corrosion resistance.

Duradek is lightweight and therefore easily handled in installation and costs less to ship than steel grating. Furthermore, because of the unique cross-bar construction, Duradek grating panels can be easily modified to fit almost any plant requirement
