This is a rain grate made of ductile iron, which is a component of the drainage system:

1. Basic properties

Material: Ductile iron (the surface shows a rough texture and metallic color after casting, with high strength and toughness), can withstand vehicle and pedestrian loads, and resists deformation and impact.

Function: As the "grate" of the stormwater gully, it intercepts garbage and leaves and guides rainwater into the underground ditch, which is a key link in the "entrance filtration" of urban drainage.

2. Design and performance

Grate structure: a combination of long strips + cross pores, with high porosity (ensuring drainage efficiency) and blocking large debris; the edge has raised blocks (casting process characteristics, which also assist in anti-slip and positioning installation).

Bearing level: suitable for sidewalks, community roads, and non-motorized vehicle lanes.

3. Application scenarios

Municipal drainage: with concrete/metal gullies on both sides of the road, it can quickly collect rainwater and prevent road surface waterlogging.

Community/factory area: used in green belts, parking lots, and drainage outlets outside factories to intercept debris (leaves, mud and sand) and reduce the risk of pipe network blockage.

4. Maintenance
It is necessary to regularly clean the porous debris (to prevent blockage from affecting drainage) and check the rust on the cast iron surface (although ductile iron is corrosion-resistant, it still needs protection in a humid, acidic and alkaline environment for a long time, and can be painted with anti-rust paint).

Simply put, this is a practical part in the urban drainage system that is "down to earth". It relies on ductile iron construction + grille design to solve the "drainage + garbage interception" problem and silently guard rainy day travel~
