The popularity of resin manhole covers is fundamentally that their comprehensive performance and economic indicators have surpassed those of cast iron manhole covers, and it can also solve the problem of theft of cast iron manhole covers. At the same time, it can reduce the consumption of resources and has important economic and social values. The manhole cover has the advantages of light weight and high strength, simple molding, low car milling noise, good chemical resistance, good acid and alkali resistance, and beautiful appearance.It has advantages not found in cast iron manhole covers. The surface pattern of the resin inspection manhole cover is beautifully designed and bright in color Adjust, beautify the urban environment, easy to use, light weight, resin inspection manhole cover has no recycling value, natural anti-theft, resin inspection manhole cover through scientific formula, advanced technology, perfect technical equipment to make this product at -50 ° C --- Normal use in + 150 ° C environment, acid and alkali resistance, corrosion resistance, abrasion resistance, vehicle rolling resistance, long service life, meet the standard of resin manhole cover.
FRP composite manhole cover features:
1. the performance is very stable, whether it is used in high temperature, or in corrosive acid and alkali occasions, the performance is not affected by it. In addition, the method of sandwiching sand in production can be used to achieve the characteristics of enhanced anti-skid performance.
2. Long life: Under the same conditions, the life of wood is only 1-2 years, the life of metal sheet is only about 3 years, and the life of FRP can reach more than 15 years.
3. Social benefits: In public places, the frequently used tree pool cover products often have security problems and are very easy to be stolen. FRP is made of composite materials and has no recycling value, which can effectively achieve the anti-theft effect. Far-reaching social benefits.
4. high comprehensive value: from the production cost, construction cost, product performance characteristics, service life, maintenance work and other aspects of analysis, glass fiber reinforced plastic material tree pool cover is undoubtedly quite cost-effective.
