Installation Instruction:
To ensure the optimal use of our composite material manhole covers, it is essential to prioritize the quality of installation. Focus on achieving precise dimensions, a robust installation, easy accessibility, and an aesthetically pleasing look. In line with the technical standards for composite material manhole covers, we have established the following installation guidelines to ensure superior performance:
1. The inner diameter (or inner length x width) of the manhole cover must be equal to or exceed the dimensions of the reserved wellhead. Failure to comply will significantly compromise the cover's load-bearing capacity.
2. During installation, it is imperative that the joint surface between the well seat and the concrete ground is flush, with no voids. Any suspended areas risk being crushed by construction equipment, such as road rollers, ultimately reducing the product's lifespan.
3. When installing manhole covers on asphalt surfaces, it's crucial to prevent construction machinery from compacting the manhole seat directly. During road construction, ensure a hole slightly larger than the well seat is reserved on the road surface. Place the cover only after the asphalt is fully laid.

2. What's FRP?
Fiber Reinforced Polymer (FRP) is a composite material made of a polymer matrix reinforced with fibers. The fibres are usually glass, carbon, aramid, or basalt. Rarely, other fibres such as paper or wood or asbestos have been used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, and formaldehyde resins are still in use. FRP are commonly used in the aerospace, automotive, marine, construction industries and ballistic armor.
3.How can you guarantee you product quality?
100% of our products will be tested before delivery. To control quality, we are using high quality material from high quality supplier.
