Fiberglass Trench Covers

When quality and safety matter, we've got you covered.

Eliminate the hassle of handling awkward and overweight trench covers made from concrete or steel. Choose fiberglass trench covers.

 

Throughout the world, fiberglass trench covers are quickly replacing rotted-out wood covers, crumbling  concrete, and warped steel. When you choose our fiberglass trench covers, you’re choosing a quality, lightweight product that will withstand the test of time. Test results are available on our 'Why Choose Fiberglass' page. Give us a call today and let’s get started: 1-253-884-4008.

▪ Lightweight: All fiberglass composite covers are easy to install with minimal manpower  requirements, eliminating the need for excess manpower and large machinery, reducing on the job injuries associated with lifting.


▪ Easily Accessible:
Lifting pins on each pedestrian & H20 cover provide easy access.


▪ Safety:
Fiberglass construction prevents conductivity of electrical currents, eliminates the need for grounding, and offers a fire-resistant finish (with a Class I or Class II fire-retardant finish option available). Each cover is made with a super non-skid diamond-patterned surface. Also available with flame retardant resin.

▪ Superior Weatherability: Our products are constructed to endure extreme weather conditions (-70˚F to 212˚F). Our C-Type fiberglass and resin mix provides excellent resistance to corrosive elements in the surrounding grade. Marine-grade, gel-coated fiberglass offers a U.V. resistant and non-corrosive, quality product that is highly resistant to chemical or natural deterioration.

 

▪ Durable: High Strength with the highest glass reinforcement content in the industry, and exclusive use of double layers of 24 oz. woven roving reinforcement cloth support an extra long product life.
