1. High load rating and strength  

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

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.  


2. Against theft and safety options  

Zero theft value, reducing potential accident and further maintenance cost caused by thieves. 

Surface antislip thread guarantees safe road condition even in extreme weather. 

Locks are available as an option molded into the cover to improve security rate. 

Non-electricity conduction and non-heat conduction.  


3. Lightweight  

Compared with CI & DI manhole covers, composite covers are 50% lighter. 

Lightweight allows more loading per vehicle, more convenient transportation and economical saving. 

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.

More than 30 years service life without crack and color fading, comparing to 5 years of cast iron. 

Anti corrosion, water, dust and pets tight, well sealed prevent poisonous gas leaking out. 

Without displacement, freely radio signal passing. 

Higher and lower temperature tolerance with the range -40°C-200°C.  

Wear indicators available when thread depth is in a danger value.  


5. Free design  

Composite material itself allows for innovative design features, clint logo is available as an option.  

Much more clear resolution ratio of surface design than cast iron or BMC.  


6. Carbon footprint saving and environmental care. 

Lower embedded energy carbon emission and during manufacturing process than cast iron covers.
