The heavy nodular cast iron manhole covers are based on the load required by the pavement or manhole covers. The light nodular cast iron manhole covers are used on general roads, and heavy ones are mainly used on the roads passing by container trucks or heavy trucks.
The heavy nodular cast iron well covers 400KN, which has the advantages of corrosion resistance, aging resistance, acid and alkali resistance, toughness, long life, high bearing capacity, easy deformation and good safety. Can load more than 360kN or super steam -20 class main car.
1, anti jump cover: the use of shockproof aprons, so that the vehicle does not produce noise during the process, in line with environmental protection requirements。
2, beautiful: beautify the city environment, spray black asphalt, so that the product appearance, clean and tidy.
3, anti-theft: ordinary anti-theft design, new anti-theft design, manhole cover and well ring with high-strength bolt connection, integrated design。
4, high bearing capacity, bearing capacity is more than other types of products, bearing pressure, fracture prevention, safety accidents such as vehicle crashes。
5, good safety: Heavy Nodular Cast iron manhole cover tightly combined, will not produce jumping, seesaw, sound, shift and other phenomena, no noise, safe and reliable.
6, long life: corrosion resistance, no pollution, no maintenance, can be used for more than 50 years.
7, anti slip: Heavy Nodular Cast iron cover surface has a special anti-skid pattern, increase friction, prevent rain, snow, ice cover to make pedestrians slip.
