      Which is the best manufacturer of nodular cast iron manhole covers in Qinghai? Spheroidal graphite Cast iron well ring cover It is mainly made of nodular cast iron. The quality of the well cover is related to the spheroidization rate. Anti rust asphalt paint is commonly used for surface layer of castings. Of course, the surface of the nodular cast iron manhole cover is also treated with antirust asphalt paint and can be delivered only after passing the inspection.
