Ductile iron manhole cover is a kind of manhole cover that is used a lot nowadays. It is quite famous in the manhole cover industry. It has been very popular in the manhole cover industry in recent years. Why is nodular cast iron manhole cover so popular? Take a look You will know its advantages:
List of advantages of ductile iron manhole covers:
1. Anti-falling and strong bearing capacity; the bearing capacity of ductile iron manhole covers is better than the national standard (360KN), and can withstand the rolling of various heavy trucks, effectively avoiding accidents caused by manhole covers falling.
2. Anti-slip: Ductile iron manhole covers have exquisite casting technology, which makes the product lines clear. The surface of the manhole cover has a unique anti-skid pattern, which increases friction and prevents pedestrians from slipping due to rain, snow and ice.
3. Good material: Ductile iron manhole covers are usually made of ductile iron QT500-7 material, so that the product has strong compression resistance, bending resistance, impact resistance, heat resistance, cold resistance, wear resistance, acid and alkali resistance, aging resistance, and is not easy to deform and other characteristics.
4. The anti-theft function of ductile iron manhole covers is good. No matter what kind of manhole covers, anti-theft is very important. After the development of ductile iron manhole covers in recent years, manufacturers have gradually achieved a good anti-theft system.
5. Anti-noise, no noise; each set of ductile iron manhole covers has been processed by three procedures, so that the contact surface between the manhole cover and the well ring is zero, so that the two can fit seamlessly, and no noise will be generated when vehicles pass by.
6. Beautiful appearance: the appearance design can be changed according to the customer's request to meet the different needs of customers, and then sprayed with black asphalt to make the appearance of the product bright and tidy.
The above is a detailed introduction to the advantages of ductile iron manhole covers. After reading it, you will know why nodular cast iron manhole covers have always been favored by the market.
