1.High load rating and strength 

 

V As hard as cast iron, ductile iron manhole cover. Barcol hardness 63

V Designed to meet and exceed A15/B125/C250/D400/E600 loading rating, according to EN124:1994. We also could design the products according to the customers' local standard such as AS3996, FACTA standard, U.S.A. Standard AASHTO, etc.

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 CI & DI manhole covers, composite 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. And we could provide some good accessories to help customers lift the cover much easier.

 

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.
