Frequently Asked Questions
C250 is typically used for curbside or parking areas, while D400 is designed for areas subject to heavier traffic, such as main carriage ways of roads.
Bitumen painting provides a dense, hydrophobic layer that protects the ductile iron from moisture and chemicals found in sewage and stormwater.
Yes, they are specifically designed to protect telecommunications cables and infrastructure from external pressure and environmental elements.
Ductile iron contains spheroidal graphite, which gives it much higher strength and ductility, preventing the sudden cracking common in grey iron.
Absolutely. The LWRC series is engineered to handle high-volume water flow and heavy load pressures typical of storm drainage environments.
Lead times vary by quantity and specification, but our streamlined manufacturing process for metal products ensures competitive delivery schedules.
