SMC Composite Manhole Covers Characteristic:
1. Durable Service Life.
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.
2. Against Theft and Safety Options
Zero theft value, reducing potential accident and further maintenance cost caused by thieves.
Surface anti-slip 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. High Load Rating and Strength
Similar hard property as cast iron, while have a overwhelming advantage on stretch recovery.
Designed to meet and exceed A15/B125/C250/D400/E600 loading rating, according to En124: 1994.
Less noise and lower vibration transmissions.
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 in jury.
5. Free Design
Composite material itself allows for innovative design features, client logo is available as an option.
Much more clear resolution ratio of surface design than cast iron or BMC.
