Do you need a closed trench cover that combines non-conductivity, thermal insulation, non-slip, and light weight? Why not think about our FRP trench cover?
Compared to the FRP open mesh grating, FRP trench cover has higher stiffness and provides a solid flooring to cut off the possibility of electric shock for power engineering. Compared with the metal cover with poor corrosion resistance and the wooden cover with poor material quality, it has the best sealing performance, widely used in sewage treatment plants and chemical plants to control the underground odor to prevent the pollution of the working surface. Its anti-slip and abrasion resistance are far better than the general metal cover, wooden cover, plastic cover, etc., incredibly durable and prevent tripping hazards for narrow heels.
