2,Main Features of the Ductile Iron Manhole Cover:

‍1. High load capacity & resilience

Hardness is same as cast iron, while FRP manhole covers have overwhelming advantages on resilience recovery. They are designed to exceed A15/B125/C250/D400 load capacity, according to EN124: 1994.

2. Designed structure & pressure dispersion

Arc-shaped bottom structure allows the pressure they bear disperse averagely on the whole surface. Besides, the products are made not by SMC, it was put in several layers of fiber cloth to enhance the structures. So they are stronger than SMC composite manhole covers.

3. Consequences of temporarily overloading

Temporarily overloading may cause smash of concrete covers, seriously deformation, even slightly split. But this will not happen to FRP fiber cloth manhole cover.

4. Safety options

There is no metal contain, directly reducing potential accident or further maintenance costs caused by thieves. Anti-slip surface offer a safe road condition even in extreme weather.

5. Light weight

Compared with cast iron manhole cover, FRP manhole cover is 30% lighter.

Light weight allows more loading per vehicle, more convenient transportation and economical savings.

Allows a safer working condition, which single workers is enough for installation without risk of injury.

5，FAQ:

We have organized several common questions for our clients，may help you sincerely：

Q. Can I fit a square manhole cover into a round chamber?

A. Yes, there are a select few manhole covers which are square-to-round, meaning they will fit square or round chambers.
