Product Name: good quality Rectangle Square Corner Ductile Iron Manhole Cover
Rectangle square corner ductile iron manhole cover
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.

- Customization can be available.
Feature
- High elongation strength, high tensile strength, good carrying capacity, durable finish.
- Resistant to corrosion, attack, abrasion, skid.
- Ductile iron manhole cover has higher toughness, ductility and strength, better corrosion resistance than cast iron manhole cover.
- Easy to construct, install.

Application
Ductile iron manhole cover is mainly used for drain in municipal, water conservation, electrical industry, slow moving heavy traffic, fast moving heavy traffic. It also can be used in main roads, highways, driveways, car parks, sidewalks, docks, ports, airport runways, etc.
Standards and features:
1.high strength. Tensile strength σs≥420MPa, yield strength σs≥300MPa, same as low carbon steel, three times that of gray iron
2.Good toughness. The impact value is similar to that of medium carbon steel, which is more than 10 times that of gray iron material.
3.Good plasticity. The elongation is as large as 7%, which is similar to high carbon steel, while the gray iron steel has an elongation of zero.
4.Strong corrosion resistance. In the water spray corrosion test, the corrosion amount in 90 days is only one tenth of that of the steel pipe, which is one tenth of that of the gray iron pipe. The service life is twice that of gray cast iron, which is 5 times that of ordinary steel pipe.
