Ductile Iron Manhole Cover for Municipal Engineering

Ductile iron manhole cover, as the name suggests, is made from ductile iron which adds graphite in the cast iron. The form of graphite is spherical, and graphite will not influence the mechanical character of the cast iron. Cover shapes could be round, square, rectangle, or double triangle. Load bearing classification includes A15, B125, C250, D400, E600, F900. Ductile iron manhole cover has high elongation strength, high tensile strength, good carrying capacity and durable finish. It also has higher toughness, ductility and strength, better corrosion resistance and plasticity than cast iron manhole cover. It can be used in municipal, water conservation, electrical industry, slow moving heavy traffic, and fast moving heavy traffic.
