FRP SMC manhole characteristics
(1)High intensity:
The manhole cover is made by polymer composite material with steel skeleton, and is moulded under hightemperature and pressure. It can hold a ultimate 54 tons according to the test result, which meets and evenexceeds the latest criterions in CJ/T211-2005,promulgated by the Ministry of Construction of the People'sRepublic of China.
(2)Elegantappearance:
The patterns of the manhole cover are well designed with various colors,which can beautify the environmentof the city.
(3)Lighter in weight:
It only weighs one third of the cast iron manhole cover that it's easier for transportation, installation andemergency repair, Besides, It also lightens labour intensity immensely.
(4)Good anti-theft:
It is made by polymer composite material with no no recycling value that prevent being stolen.It is set withlock structure which can secure the belongings under it. Thus it keeps away these accidents which werecaused by the missing of manhole cover.
(5)Highdurability:
It is made by polymer material which has a larger molecular and better stability, and works under thetemperature between 50ºCbelow zero and 150ºCabove zero with the Scientific formulation advanced skillsand Technical equipment.
(6)Highprecision:
The cover can fit together with the frame perfectly, as it is Moulded under high temperature and pressure.It overcomes the problems of "moving, spring and nosy", which exist in covers made by cast iron and cement.So it is improves traffic capacity and comforts when drying.
(7)Corrosion-resistance:
According to the test of the National Research & Analysis the Center of Chemical Building Materials, theproducts is corrosion-resistant and has a 3 level capability of ageing resistance. Thus it has a longer service
