D400 GRP manhole cover

The FRP fiberglass reinforced plastic compound manhole cover is made of glass fiber and resin as basic materials,curing agent and accelerator as auxiliary materials.Fiberglass reinforced plastic compound round manhole cover has many advantages,such as light weight,high strength,excellent fatigue resistance and safety.Its comprehensive performance and economic index have exceeded that of cast iron manhole covers,and it can also solve the problem of stolen cast iron manhole covers.At the same time,it can reduce the consumption of resources and has important economic and social value.

Features

1.Anti-theft performance is strong:the material of resin composite well cover has no recycling value,and it is very difficult to removesteel bar(the cost of removing steel bar exceeds the value of steel bar),so it has the function of active anti-theft.

2.Bearing capacity is large:special bottom structure is adopted at the bottom of the pot,which enlarges the stress area by more than ten times or even dozens of times.The continuous reinforcing fibre yarn used ensures that the fibre yarn and the fiberglass cloth are integrated from the material,so that the product has sufficient carrying capacity.And it meets the national standard.

3.Long service life:through the use of high performance resin,glass fiber and special production process formula,the permeation of resin in glass fiber is ensured,and the bonding force between the two is greatly enhanced,so that the material under cyclic load does not produce internal damage,ensuring the service life of the product and other resin composite well caps.The disadvantage of poor adhesion was eliminated.

4.Beautiful and practical,high-grade:according to the needs of high-end customers,can make complex trademarks and a variety of colors in the same well cover surface personalized design,so that the pattern is delicate,bright and distinct.

5.High/Low temperature resistance,good insulation and corrosion resistance:product corrosion resistance,non-toxic and harmless.

6.Environmental protection,anti-skid,low noise:the product does not skid,no harsh noise and reverse phenomenon after rolling.At the same time,due to the light weight of the product and the precise closure of the cover and seat,the problems of jumping,stirring,noise and displacement of other inspection covers are overcome.
