Composite manhole cover for sale

Advantage of Composite Manhole Covers

1. High load rating and strength

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

v Designed to meet and exceed A15/B125/C250/D400 loading rating, according to En124: 1994.

v Less noise and lower vibration transmissions.

2. Against theft and safety options

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

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

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

v Non-electricity conduction and non-heat conduction.

3. Lightweight

v Compared with cast iron manhole covers, composited covers are 50% lighter.

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

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

4. Durable service life.

v More than 30 years service life without crack and color fading, comparing to 5 years of cast iron.

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

v Without displacement, freely radio signal passing.

v Higher and lower temperature tolerance with the range -40°C-200°C.

v Wear indicators available when thread depth is in a danger value.

5. Free design

v Composite material itself allows for innovative design features, clint logo is available as an option.

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

6. Carbon footprint saving and environmental care.

v Lower embedded energy carbon emission and during manufacturing process than cast iron covers.
