What are the benefits of using a ductile iron manhole cover?
- Ductile iron is an incredibly robust and durable material, which means it can take the weight of heavy traffic without compromising the product's structural integrity.
- D400 ductile iron manhole covers are resistant to cracking and breaking, even in hostile weather conditions, which expands their lifespan.
- This product has anti-slip technology which is a safety feature. This significantly reduces the risk of accidents which could be caused by slipping or skidding.
- Ductile iron covers have a superior lifespan to those made of materials such as concrete, as they are resistant to corrosion, rust, and other types of chemical damage.
- This product is designed to minimise vibrations caused by vehicle traffic, which contributes towards its safety.
