1)Material and Structure
Material Composition: Made from ductile iron, which is cast iron with a spheroidal graphite structure. The graphite is in the form of nodules rather than flakes, giving the material high strength and ductility.
Alloying Elements: Often contains elements like silicon, manganese, and small amounts of magnesium or cerium to promote graphite spheroidization, enhancing resistance to impact and fatigue.

2)Mechanical Properties
High Strength: Can withstand heavy loads (e.g., vehicle traffic) due to tensile strength typically ranging from 400–800 MPa, far exceeding that of gray cast iron.
Ductility: Capable of deforming without breaking, which reduces the risk of cracking under stress. Elongation rates can reach 10–15%.
Impact Resistance: Resilient against sudden loads, making them suitable for high-traffic areas.

3)Applications
Urban Infrastructure: Used for sewer systems, water supply networks, electrical or telecommunication conduits, and stormwater drains.
Public Areas: Installed in roads, sidewalks, parks, and commercial districts, requiring minimal maintenance over long lifespans (often 30+ years).

4)Advantages Over Other Materials
Cost-Effective: While initially more expensive than concrete or plastic covers, their longevity and low maintenance costs make them economical.
Recyclability: 100% recyclable, contributing to environmental sustainability.
Load-Bearing Capacity: Ideal for heavy-duty applications, ensuring safety in high-traffic zones.
