- Why ductile iron?
Most manhole covers are made of ductile iron because of its strength, durability, and cost-effectiveness. Here are the key reasons:
1. High Strength & Load Capacity – Ductile iron is much stronger than gray iron, allowing manhole covers to withstand heavy loads from vehicles and machinery without cracking or breaking.
2. Impact & Fatigue Resistance – It has excellent ductility (hence the name), meaning it can absorb shocks and resist cracking under repeated stress, making it ideal for roadways.
3. Corrosion Resistance – Ductile iron has good resistance to rust and environmental damage, especially when coated or treated, ensuring a longer lifespan in different weather conditions.
4. Cost-Effectiveness – Compared to other materials like steel, ductile iron provides a great balance between performance and affordability. It’s easier to cast into complex shapes and requires less maintenance.
5. Safety & Security – Due to its weight and durability, ductile iron covers are harder to displace or steal compared to lighter materials like plastic or composites.
6. Recyclability – Ductile iron is 100% recyclable, making it an environmentally friendly choice for infrastructure projects.
