Ductile iron grate is a component used in drainage systems, usually used in drainage and ventilation systems in roads, squares, residential areas, etc. It is made of ductile iron material and has excellent mechanical properties and corrosion resistance. The following is some detailed introduction about ductile iron grate:
Material properties:
Ductile iron: cast iron obtained by spheroidization and inoculation, its graphite exists in spherical form, this microstructure gives the material good toughness and strength.
Mechanical properties: Compared with gray cast iron, ductile iron has higher tensile strength and ductility, making the grate less likely to break when under heavy pressure.
Design and structure:
Multiple specifications: Ductile iron grates usually have a variety of specifications and sizes to adapt to different use environments and load requirements.
Surface treatment: usually anti-rust treatment, such as spraying asphalt, to improve its corrosion resistance.
Advantages:
High strength: Able to withstand higher loads, suitable for installation in areas that need to withstand frequent traffic of vehicles and pedestrians.
Corrosion resistance: Good resistance to water, chemicals and climate change, suitable for long-term use.
Safety: Various designs, can effectively prevent slipping, and ensure the safety of pedestrians and vehicles.
Application scenarios:
Commonly used in drainage systems in municipal engineering, industrial plants, residential areas, commercial pedestrian streets and other areas.
Suitable for installation in sidewalks, roadways, green belts and other locations.
Through the above characteristics, ductile iron grates play an important role in the construction of modern urban infrastructure, which can not only meet functional requirements, but also have both economy and durability.
