Frequently Asked Questions
Ductile iron contains magnesium, which creates spherical graphite nodules. This makes the material much stronger and more flexible, preventing the brittle fractures common in grey cast iron.
Yes, C250 is designed for areas with moderate loads, typically suitable for car parks, residential driveways, and paved areas used by light vehicles.
Bitumen painting provides a waterproof and chemical-resistant barrier that prevents oxidation of the iron, significantly extending the product's life in wet underground environments.
As a specialist in metal products manufacturing, we can provide various modifications to our ductile iron range to meet specific municipal or project guidelines.
Each unit undergoes load-bearing tests to ensure it meets the C250 pressure threshold without permanent deformation or structural failure.
Lead times vary based on quantity and customization; however, our optimized supply chain allows us to maintain competitive delivery schedules for global shipping.
