RX FRP MANHOLE OVERVIEW
FRP Manhole Covers are made using thermoset material for long term durability. The material comprises of cross-linked polyesters combined with Fiber-glass reinforced materials to sustain against wear-n-tear for heavy load vehicular traffic. It is 40% lighter than traditional Precast Concrete and Cast Iron covers. Provides up to 5 times more compressive strength. This resilient material withstands constant exposure to weather or sun without sacrificing security or aesthetics.

ADVANTAGES OF FRP / GRP COVERS
- Free from theft easy to handle and no risk of due to light weight.
- Does not rust due to chemical / sewage / rainwater.
- High service life as it does not corrode and has high impact resistance.
- High on aesthetics. The covers are self-pigmented and do not require periodical painting for maintenance.
- The pigment is built in the material and UV stabilized. Hence there is no peeling / fading of the colours due to sunlight.
- Resistant to extreme temperatures.
- 100% waterproof, corrosion free material with zero scalp value.
- Light in weight & easy to handle.
- Available in different granite finishes.
- Can withstand heavy loads of traffic.
