Frequently Asked Questions
D400 indicates that the cover is designed to withstand a test load of 400kN, making it suitable for main roads, highways, and parking areas where heavy vehicles travel.
Bitumen painting provides a waterproof and corrosion-resistant layer that protects the ductile iron from oxidation and harsh chemical exposure in sewage systems.
Ductile iron is significantly stronger and more flexible than gray iron, meaning it bends rather than cracks under pressure, which is critical for road safety.
Yes, we offer customization services for various dimensions and load requirements to match specific municipal project needs.
Depending on the traffic volume and environmental conditions, a high-quality ductile iron cover like the LWRC7001 can last several decades with minimal maintenance.
Absolutely. Due to their high load capacity and corrosion resistance, they are ideal for industrial zones, factories, and heavy machinery areas.
