Advantage of Composite Manhole Covers

1.High load rating and strength

vSimilar hard property as cast iron, while have a overwhelming advantage on stretch recovery.

vDesigned to meet and exceed A*5/B**5/C**0/D**0 loading rating, according to En**4: ***4.

vLess noise and lower vibration transmissions.

2.Against theft and safety options

vZero theft value, reducing potential accident and further maintenance cost caused by thieves.

vSurface anti-slip thread guarantees safe road condition even in extreme weather.

vLocks are available as an option molded into the cover to improve security rate.

vNon-electricity conduction and non-heat conduction. 

3.Lightweight

vCompared with cast iron manhole covers, composited covers are *0% lighter.

vLightweight allows more loading per vehicle, more convenient transportation and economical saving.

vAllows a safer working condition, which a SINGLE worker is enough when installation without risk of injury.

4.Durable service life.

vMore than *0 years service life without crack and color fading, comparing to 5 years of cast iron.

vAnti corrosion,water, dust and pets tight, well sealed prevent poisonous gas leaking out.

vWithout displacement, freely radio signal passing.

vHigher and lower temperature tolerance with the range **0°C***0°C.

vWear indicators available when thread depth is in a danger value.

5.Free design

vMuch more clear resolution ratio of surface design than cast iron or BMC.

6.Carbon footprint saving and environmental care.

vLower embedded energy carbon emission and during manufacturing process than cast iron covers
