High load rating and strength
Similar hard properties as cast iron, while have an overwhelming advantage on stretch recovery.
Designed according to En124: 1994.
Less noise and lower vibration transmissions.
Against theft and safety options
Zero theft value, reducing potential accidents and further maintenance costs caused by thieves.
Surface anti-slip thread guarantees safe road conditions even in extreme weather.
Locks are available as an option molded into the cover to improve the security rate.
Non-electricity conduction and non-heat conduction.
Lightweight
Compared with cast iron manhole covers, composited 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.
Durable service life.
More than 30 years of service life without crack and color fading, compared to 5 years of cast iron.
Anti-corrosion, water, dust, and pets tight, well-sealed prevent poisonous gas from leaking out.
Without displacement, a radio signal passes.
Higher and lower temperature tolerance with the range -40-200.
Wear indicators are available when thread depth is in a danger value.
Free design
Composite material itself allows for innovative design features, and the clint logo is available as an option.
Much more a clear resolution ratio of surface design than cast iron or BMC.
Carbon footprint saving and environmental care.
Lower embedded energy carbon emission and during the manufacturing process than cast iron covers.
New material and manufacturing technology save carbon footprint.
High load rating and durable strength, Against theft and safety options, Lightweight, Durable service life, Free design.
