Glass Fiber Reinforced Plastic (GRP) Manhole Cover (Continuous Wrapping Process) (Abbreviated as GRP), a new type of manhole cover formed by the continuous wrapping process, is composed of resin, glass fiber (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 its lightweight, high strength, corrosion resistance, and excellent hydraulic properties, also features the following characteristics.

High axial compression strength, high allowable thrust

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

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