1. Against theft
JINMENG SMC manhole cover is non-metallic, non-conductive and
non-sparking. It has no value of recycling, thus completely solving
the problems caused by theft.
2. High load capacity
SMC manhole cover main components are fibreglass and unsaturated
resin. JINMENG's patent is W-SMC which is the whole and the most
hard material. It is strong enough to support any load. There's no
problem for its load capacity as strong as ductile iron. JINMENG's
existing moulds load capacity are A15, B125, C250, D400, E600.
3. Free design
It can be designed according to the user's demands, including
color, logo, surface pattern, and any other specification.
4. Long life
Range of UV stable colours available that will not flake or crack.
Minimum lifespan of 30 maintenance free years.
5. Well sealed
It can be used hermetically, and effectively prevent those
poisonous gases leaking out from cesspool. Well sealled, no noise
pollution or rebound.
6. Good wear and corrosion resistance
It will never rust because it has good wear and corrosion
7. High and low temperature resistance
Excellent insulator against heat ( from -40 degree to 300 degree)
8. Lighter weight and more competitive price
Compared with cast iron manhole covers, the weight of composite
manhole cover especially SMC manhole cover is lighter. The result
is composite manhole cover is more convenient to transport, install
In all, the price of composite manhole cover is much lower than the
same specification cast iron covers.&
