Features
| 1.High strength: it 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. |
| 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℃, + 150℃. |
| 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. |
