FRP manhole cover is to solve the steel, iron manhole cover is easy to rust and stolen, too heavy, brittle crack defects and improve the service functions and economic and social benefits to the development of the manhole cover.

FRP / composite material manhole cover with glass fiber and its products (glass cloth, belt, felt, yarn, etc.) as a reinforcing material, synthetic resin as matrix material, mainly made of unsaturated polyester resin, fillers, initiator, thickening agent, low shrinkage additives, membrane module agent, pigment and enhanced materials and other components.

Characteristics:

1. light weight, glass steel manhole cover weight is only iron cover 1/4, engineering installation and use of open and close is convenient and flexible.

2. good self-locking performance, glass steel round manhole cover and the manhole seat unique constraint link structure, with preventing to drive a car after covers jumped off the self-locking function of the well base.

3. high strength, glass steel material tensile strength of Q235 steel and equivalent compressive strength than c30x high more than doubled, anti impact, vibration, fatigue, fracture performance is superior to steel, iron, and other materials, used as a bearing structure of manhole covers, strength safety conditions than iron manhole cover more easy to be satisfied.

4. to theft and loss, glass steel products recycling utilization value, used as covers to avoid iron manhole covers are often steal sell scrap hidden dangers, so as to prevent the well cover from stolen made adult, car fell into the card in the well of the traffic accident, reduce owners of the economic loss and responsibility for the accident.

5 corrosion, glass steel material natural corrosion resistance, used as acid, alkali, salt, sewage and other corrosive media environment covers with economic competitive advantage.

Usage:

Mainly used for municipal roads, water supply, power supply, post and telecommunications, street lamps, residential area, landscape planning, oil and gas production, chemical production, drain cover, sanitation and other project.

1, heavy duty: motor vehicle access road or parking space.

2, light: the prohibition of motor vehicles to enter the green space, passage, bike lanes or sidewalks.

3, ordinary type: car 10 and below the vehicle passage of the road or parking space.
