Product Description
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.
6. Long service life
Strong resistance of acid, alkali, weathering, anti corrosion of water, dust, manhole covers used for gas are well sealed which prevent poisonous gas leaking.
Temperature tolerance is at the range of -40° C-200° C.
7. Customer design
FRP manhole covers allow customers' innovative design, logo, or etc. We have our own design team who can also offer design work for customers.
8. No color fading
The cover is not sprayed in surface but painted in whole material so that the color can keep no fading.
Zhengzhou PRO-Covers Municipal Facilities Co., Ltd. is the only company engaged in research and development of new environmental friendly materials, production and sales of high-tech enterprises. The main products includes FRP Manhole covers, art manhole covers with frame, FRP gratings of various kinds. Our products strictly produced according the EN124. Products lifespan can reach to more than 30 years.
The latest research results: 700mm diameter manhole cover, edge thickness is only 25mm, but it can carry up to 100 tons, which is a mavelous result in current manhole industry.
