{dede:global.cfg_gsname/} | Updated: 2020-01-16 06:31:17
1. Light weight. The resin composite square manhole cover weighs only 1/4 of the iron cover. The engineering installation and use are easy to open and close.
2. Good self-locking, with self-locking function to prevent the manhole cover from jumping off the well seat after the car has passed.
3. High strength, the tensile strength of FRP material is equivalent to that of Q235 steel, the compressive strength is more than double that of C30X, and the impact resistance, vibration, fatigue, and fracture performance are better than those of steel and iron. , The strength safety conditions are easier to meet than iron manhole covers.
4. Anti-theft, glass fiber reinforced plastic products have no waste recycling value. Used as manhole covers can avoid the hidden dangers of steel manhole covers that are often stolen and sold as waste products, thereby preventing traffic accidents caused by theft of manhole covers, causing people, cars to fall in or getting stuck in the well, and reducing owners. Economic loss and accident liability.
5. Corrosion resistance. The glass fiber reinforced plastic material is naturally corrosion resistant. It is used as a manhole cover for corrosive media environments such as acid, alkali, salt, sewage, etc. It has technical and economic competitive advantages.
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 forming, low rolling 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 design of resin inspection manhole covers is exquisite, and the colors are bright and beautiful 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.
