Installation Instruction:
To guarantee the utmost performance and longevity of our composite material manhole covers, meticulous attention must be given to installation quality. This involves ensuring precise dimensions, robust installation, seamless opening, and maintaining a pristine and visually appealing surface. In alignment with the technical standards of composite manhole covers, we have crafted these essential installation guidelines:
1. The inner diameter (or inner length x width) of the manhole cover must meet or exceed the reserved wellhead dimensions. Failure to comply will significantly compromise the cover's load-bearing capacity.
2. During installation, the joint surface between the well seat and the concrete ground must be snug, ensuring there are no suspended areas. Any gaps could result in the cover being crushed by road rollers during construction, thereby reducing its service life.
3. For installations on asphalt pavement, it is crucial to prevent direct compaction by construction machinery. During road construction, ensure a hole slightly larger than the well seat is reserved in the road surface. Place the cover only after the asphalt is fully laid to avoid compromising the structure.

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.
