E600 Ductile Iron Manhole Cover is a heavy-duty infrastructure essential designed for extreme-load scenarios. Made of ductile iron-processed with nodularizing agents to turn graphite into spherical structures -it boasts far higher toughness and durability than ordinary cast iron.

The "E600" rating means it withstands up to 600 kN (60 tons) of vertical pressure, complying with the EN 124 standard. Its key strengths include anti-settling design (fitting tightly with road surfaces ), slip resistance (≥70 PSRV), and low noise from traffic impact. It's ideal for highways, ports, and industrial zones where heavy trucks operate frequently.

E600 Ductile Iron Manhole Cover Typical Application Scenarios:
Heavy industrial zones, ports, and logistics centers (for forklifts and heavy trucks)

With reliable load-bearing capacity and long service life, E600 Ductile Iron Manhole Cover is a trusted choice for critical infrastructure protection.

FAQ

Q: 1.What is a ductile iron manhole cover? How does it differ from gray cast iron covers?

A: It's made of ductile iron (spheroidized graphite) with high strength & toughness. vs gray cast iron: tensile strength (≥500MPa vs 200-300MPa), elongation (≥7% vs <1%), service life (30-50 years vs 10-15 years).

Q: 2.What is "spheroidization treatment" in ductile iron manhole covers? What does it do?

A: Adding spheroidizers (e.g., Mg alloys) to make graphite spherical. Functions: reduce matrix splitting, enhance toughness, improve corrosion resistance

Q: 3.CAN I ASK A SAMPLE?

A: Yes, just need you bear the delivery charge.

Q: 4.CAN I HAVE MY OWN LOGO ON THE PRODUCT?

A: Yes, you can send us your drawing and we can make your logo.

Q: 5. CAN YOU PRODUCE THE PRODUCTS ACCORDING TO MY OWN DRAWINGS?

A: Yes, we can produce the products according to your drawings that will be most satisfy you.
