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.
