China Suppler Plastic Composite Fiberglass FRP/SMC/GRP Manhole Cover 
About FRP electrial cover
FRP manhole cover is Fiberglass reinforced plastic covers, It adopts unsaturated polyester resin as matrix of fiber reinforced thermosetting composite material, also called regiment shape mould plastic , with pressure molding technology is made, is a kind of new environment-friendly power cover plate.
With high-temperature and high-pressure once moulding technology, the degree of polymerization, high density, long service life, have wear-resisting, corrosion resistant, non-rusty, non-pollution, free maintenance etc.

Product features:
1.High strength: FRP manhole cover is the high polymer synthetic material,it is based on steel skeleton,one time can be finished through high heat molding, its highest detection results can upto 54 tons, meet and exceed the People's Republic of China ministry of construction issued the latest CJ/T211-2005 standard.
2. Beautiful appearance : the surface of the manhole cover exquisite decorative pattern design, can be made into all kinds of color, it is beautify the urban environment.
3. light weight: the weight was only about a third of cast iron products, convenient for transportation, installation, repair, greatly reduce the labor intensity.
4. Anti theft: this synthetic material recycling value, natural anti-theft;With locking structure, the realization of borehole property security.Black hole can completely eliminate the "city" accidents.
5. Strong weather resistance: the product molecular weight, chemical stability strong sex of high molecular weight materials as raw material, through scientific formula, process equipment, perfect technology can make the product in normal use - 50 ºC, + 150 ºC.
6. High precision : because the product is moulded by the high temperature, build a small joint clearance, overcome the cast iron, cement type of manhole cover such problems as "running, jumping, ring", improve the traffic capacity and driving comfort.
7.Corrosion resistance.Products by the national chemical building materials test center testing, has an obvious ability of acid and alkali resistance, corrosion resistance, anti-aging index reaches 3 above, use fixed number of year is longer than the other.
Our FRP manhole cover products have been used in a large number of municipal construction in the country, well received by users and experts.
