The Distinction Between Ductile Iron Manhole Covers and Ordinary Covers – Highlighting Hongxinwei’s Superior Quality

Key Differences Between Ductile Iron and Ordinary Manhole Covers
Ordinary manhole covers, often made from traditional cast iron or composite materials, are limited in their load-bearing capacity and resistance to wear. Over time, these covers may crack, deform, or loosen, posing safety hazards to both pedestrians and vehicles.

In contrast, ductile iron manhole covers are manufactured with a special nodular graphite structure that significantly enhances toughness and resilience. This unique composition not only improves impact resistance but also ensures superior load capacity. Ductile iron covers can withstand heavy traffic conditions, making them especially suitable for highways, industrial zones, and urban roads.
