Wholesale Price Lockable Heavy Duty SMC Fiberglass Composite FRP GRP Manhole Covers
FRP(Fiber reinforced plastic) is newly developed material of manhole covers.Before FRP came into existance,manhole cover were traditionally manufactured from concrete, steel fibre concrete,cast iron,ductile iron or PVC material, but these materials had their own shortcomings like low load carrying effciency. FRP is considered to be the best alternate material for manhole covers as it has longger lifespan and has the capacity to withstand heavy loads.Increase in heavy traffic and expensive metals completely replaced traditional covers with FRP manhole covers.
Characteristics & Advantages
1. High load rating and strength
Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.
Designed to meet and exceed A15/B125/C250/D400/E600 loading rating, according to En124: 1994.
Less noise and lower vibration transmissions.
2. Against theft and safety options
Zero theft value, reducing potential accident and further maintenance cost caused by thieves.
Surface anti-slip thread guarantees safe road condition even in extreme weather.
Locks are available as an option molded into the cover to improve security rate.
Non-electricity conduction and non-heat conduction.
3. Lightweight
Compared with cast iron manhole covers, composited covers are 50% lighter.
Lightweight allows more loading per vehicle, more convenient transportation and economical saving.
Allows a safer working condition, which a SINGLE worker is enough when installation without risk of injury.
4. Durable service life.
More than 30 years service life without crack and color fading, comparing to 5 years of cast iron.
Anti corrosion, water, dust and pets tight, well sealed prevent poisonous gas leaking out.
Without displacement, freely radio signal passing.
Higher and lower temperature tolerance with the range -40-200 degrees.
Wear indicators available when thread depth is in a danger value.
5. Free design
Composite material itself allows for innovative design features, clint logo is available as an option.
Much more clear resolution ratio of surface design than cast iron or BMC.
6. Carbon footprint saving and environmental care.
Lower embedded energy carbon emission and during manufacturing process than cast iron covers.
New material and manufacture technology save carbon footprint.
