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.
