Cast ductile iron rainwater grating is a key component of the stormwater gully system:
1. Basic properties
Material: Ductile iron (common grades such as QT500-7). After spheroidization, the graphite inside the cast iron is spherical. The strength and toughness are far superior to ordinary cast iron, close to steel, and have excellent compression and impact resistance.
Function: As the "grate" of the rainwater gully, it is responsible for intercepting debris (leaves, garbage, etc.) and guiding rainwater to quickly flow into the ditch. It is the core component of the "inlet filtration" of the urban drainage system.
2. Design and performance
Grid structure: long gap design, reasonable porosity (ensuring drainage efficiency and blocking large-volume debris); the surface is rough with casting marks, which is the typical appearance of ductile iron after casting, and has anti-slip and wear-resistant properties.
Carrying capacity: C250 is suitable for small motor vehicle lanes, residential areas, sidewalks, non-motor vehicle lanes and other scenes.
3. Application scenarios
Municipal drainage: with concrete or metal drainage ditch, used on the edge of streets and sidewalks, quickly collect rainwater and prevent water accumulation on the road.
Community/park: used in the drainage outlets of green belts, parking lots, and landscape trails, taking into account drainage and debris interception to reduce the risk of pipe network blockage.
Industrial auxiliary: some light-load areas in factory areas will also be used to deal with daily rainwater and the initial collection of a small amount of industrial wastewater.
4. Advantages
Ductile iron material is durable (lifespan 20-50 years), anti-theft (low recycling value + heavy weight), the grille structure is simple and reliable, and it is suitable for most drainage scenarios.
In short, this is a practical component of the "first checkpoint" of urban drainage. Relying on the hard power of ductile iron + grille design, it solves the problem of "fast drainage + pollution interception" and silently guards the city from seeing the sea on rainy days~
