Features of Ductile Iron Manhole Cover:
1. High load rating and strength
v Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.
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.
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 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 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.
