Product Description

Characteristics:
1. Environmental Protection: High-performance modification of SMC sheet materials and all raw materials meet the requirements of environmental protection. It doesn't pollute the environment;

2. Save mineral resources: For iron ore resources in the increasingly tense domestic situation, we developed a high performance modified SMC sheet material instead of the traditional cast iron manhole cover which saves iron ore resources;

3. Anti-corrosion: The product is high-performance SMC sheet material, which is anti-corrosion of acid, alkali, salt and rust-proof. It can be fit in a variety of harsh environmental conditions and adapt to a wide temperature range of -50 to 150.

4. If polymer manhole cover and cast iron manhole cover in the case of same performance, the price of polymer cover is only two thirds of cast iron manhole cover;

5. The weight of polymer manhole cover is only about two-thirds of cast iron, and it is easy to transport, install, repair and convenient to construct, which greatly reduces the labor intensity;

6. For the special properties of modified SMC sheet material: The product is of convertibility, good outlook, strong color, rich color change; Use of color rather than spraying the whole material, the color lasting, smooth surface of the product, feel smooth, delicate and coordinating with the color of surrounding floor and flooring material, maintain, beautiful and practical;

7. Security: Once the material formed, it has no recycling value. Natural security, virtually eliminating the theft, which makes up the cast iron manhole cover cause frequent security incidents; We also have developed our own unique locking system to secure the equipments and facilities inside of the cover for this product. Eradicate "urban black hole" accident; It brings great convenience for the municipal and public sector management;

8. Low noise: This product is made of non-metallic materials and there is no harsh sound of metal crash when the car rolls; Greatly reduces noise pollution.

9. Long service life: Tested by the State Construction Engineering Quality Supervision and Inspection Center, the product can withstand 2 million cycles of fatigue test and the service life can reach more than three decades! It is the best alternative of cast iron manhole cover.

Introduction:
Polymer composite manhole cover branded "CHAO CAI" adopt advanced technology from Europe and America. After years of mutual corporation with Beijing University of Chemical Technology & Beijing Institute of Technology, we have obtained national patents and obtained the certificate of high-tech enterprise. It has passed the test of national authorities and the State Construction Engineering Quality Supervision & Inspection Center standards. The maximum load bearing is 90tons (for airport) and it meets international EN124 standard, all other indicators are higher than similar domestic products.
The polymer composite manhole cover is made by high-performance modified SMC sheet material through a high-temperature pressure pressing which makes it high density, strong hardness, heavy load, light weight, resist corrosion, anti-aging, anti fatigue and so on. It is the best alternative to cast iron manhole covers and can be used in urban construction of tap water wells, municipal sewage pipeline inspection wells, postal wells, telecommunications, and communication optical cable tube wells, electric power line wells, street wells, fire wells and several valve wells.
In order to meet different needs of customers, we have made different design templates which are changeable and movable. We can also design different LOGO according to customers' different needs to demonstrate a greater degree of corporate culture and to highlight top taste.
The polymer composite manhole cover has been exported to USA, Jordan, Egypt, Italy, United Arab Emirates and some other countries.
