Frequently Asked Questions
C250 is generally suitable for curbside and parking areas, while D400 is designed for heavy-duty applications such as main roads and highways with higher traffic loads.
Bitumen painting provides a waterproof and anti-corrosive layer that protects the ductile iron from moisture, salts, and chemicals found in sewage and storm systems.
Yes, the LWRC2001/LWRC2002 series is specifically engineered to protect telecommunications cables and provide secure access for maintenance.
Ductile iron contains spherical graphite, which gives it significantly higher tensile strength and flexibility compared to the flake graphite found in grey iron.
Absolutely. They are designed to withstand the pressure of standing water and the flow of storm drainage without shifting or failing.
Very little maintenance is required. Periodic inspection for surface wear is recommended, and touch-up bitumen coating can be applied if the surface is mechanically damaged.
