Glass Fiber Reinforced Plastic (GRP) Manhole Covers (manufactured using continuous winding process) (Abbreviated as GRP), is a new type of manhole cover formed by continuous winding process, composed of resin, glass fibers (continuous + chopped), and quartz sand. The cover contains:

Axially reinforced chopped glass fibers enhance the pipeline's axial compressive strength.

Product Performance Features

GRP pipe, in addition to the light weight, high strength, corrosion resistance, and excellent hydraulic properties of glass steel pipes, also has the following features.

High axial compressive strength, high allowable thrust

GRP pipe axial compression strength index > 85MPa, typical value about 95 MPa, pipeline allowable thrust exceeds traditional materials, with a longer single thrust distance. 2. Suitable for various working conditions.

GRP pipes are lightweight and high-strength, resistant to sinking in silt soil, suitable for various complex working conditions.
