Fiberglass trench manhole cover are made from composite materials such as glass fiber, resin, quartz and corundum..

Fiberglass trench manhole cover is lightweight and excellent protection against corrosion and the effects of chemicals because it is made from FRP (fiber reinforced plastic).It weighs only one seventh of the weight of an average cast iron cover and easy to remove it during maintenance.

We apply wear-resistant and climate-resistant materials on the top surface layers so that the product can be used under very harsh conditions.


We can custom make any man hole design, pattern or company logo on the surface of the covers giving a personal finish to your manhole cover project.

Application Temperature Scope

The materials used to manufacture the fiberglass trench manhole covers are important, that is why we only use quality materials. The main material that contributes to the product application is the non saturated polyester resin. It belongs to the thermosetting resin, the performance after its solidification is as follows:

1.)Longitudinal strength:250-600Mpa
2.)Compressive strength:300-600Mpa
3.)Stretch modulus:25-35Gpa
4.)Break elongation ratio:1.3-10.0%
5.)Bending strength:700-1400Mpa
6.)Curving module:25-35Gpa
8.)Relative density:1.11-1.15
10.)C250(can load 25tons) D400(can load 40tons)
11.)Volume resistivity.1*(1012-1014)cm
12.)General application temperatures in -40~80
