Advantage of Jinmeng Composite Manhole Covers
1. High load rating and strength
v Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery and bend resistance.
v Designed to meet and exceed A15/B125/C250/D400/E600/F900 loading rating, according to En124: 1994.
v Less noise and lower vibration transmissions.
2. Against theft and safety options
v Comparing with cast iron manhole cover, composite cover has zero theft value and not attractive to thieves, which reduce the 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, UV resistance.
3. Lightweight
v Compared with cast iron manhole covers, composited covers are 30% lighter.
v Lightweight allows easy of handing more loading per vehicle, more convenient transportation and economical saving.
v Allows a safer working condition, which a SINGLE worker is enough for a complete when installation without risk of injury.
v Easy of moving, ease and reduce the maintenance cost.
4. Durable service life.
v More than 30 years’ theoretical service life at regular road condition without crack and color fading, comparing to same grade of cast iron manhole cover.
v Anti corrosion,waterproof, 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℃-200℃.
5. Free design
v Composite material itself allows for innovative design features, clint logo and any other design is available as an option.
v Much more clear resolution ratio of surface design than cast iron or of other material.
6. Carbon footprint saving and environmental care.
v Lower embedded energy carbon emission and during manufacturing process than cast iron covers.
v New material and manufacture technology save carbon footprint.
