Ductile iron manhole cover en124 d400 

Ductile iron manhole covers are designed to withstand heavy loads and traffic, making them ideal for use in high-traffic areas such as roads, highways, and airports. The EN124 D400 classification means that the manhole cover is capable of withstanding a maximum load of 40 tonnes, making it suitable for use in areas where heavy vehicles such as trucks and buses are likely to pass over it. 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, an…
