Ductile iron manhole cover
2 year ago
Ductile iron is a type of cast iron that is more flexible and resilient than traditional cast iron, making it less prone to cracking or breaking under pressure. This makes it an ideal material for manhole covers, which need to be able to withstand heavy loads and frequent use without becoming damaged or worn out.
EN124 is a European standard that sets out the requirements for manhole covers and gully tops, including their load-bearing capacity, dimensions, and materials. The D400 classification is one of several load-bearing classes defined by the standard, with others including A15, B125, C250, and E600. Each classification corresponds to a different maximum load capacity, with D400 being one of the highest load-bearing classes available.
