FRP manhole cover

Introduction:

FRP Manhole cover is formed one time under high temperature and pressure. It is of high density, high stiffness, high intensity of pressure, corrosion resistance, aging resistance, light weight, and nice appearance etc. It has passed the inspection of national authorized department that every item exceeds the national standard which is suitable for the usage of civil works and fast lanes. The service life is 5-10 years longer than cast iron well cover So it is a new product that can replace other kinds of covers. Our FRP well covers have been used in many civil works, and get good reputation from customers and professors

Characteristics:

High strength; High molecular synthetic materials adopted, fitted with steel fames, which are formed under high temperature and pressure, the highest test result is more than 40 tons. Meet and exceed the standard C/T211- 2005 issued by construction Ministry of People’s Republic of China.

Nice appearance: beautiful figure design on the cover surface. The surface can be designed of any figure and color, which can beautify the city environment

Light weight: its weight is only one third of cast iron. Easy for transportation, installation, maintenance, which decrease the labor strength

Good climate resistance: large and high molecular material of chemical stability is adapted to the raw material. Scientific formula, advanced process and technology enable the FRP well cover can be used in -40°C~90°C.

Corrosion resistance: It has been inspected by national chemical construction test center that it has obvious acid & alkali resistant property. Aging resistant index can be above 3, long service life.
