Cast iron manhole cover dn 425mm, class D400=40t (Diamir 425NW) 2901164100

Durable and safe access to the sewer network

This 425 mm diameter cast iron manhole cover is a reliable solution for manholes, providing safe and convenient access to the network. Designed for installation in sanitary, rainwater, combined, industrial systems, and drainage. Made of durable cast iron, it guarantees long-term operation even in harsh conditions.

Solid construction and high resistance

The manhole cover is characterized by a load class of D400, which means it can withstand a load of up to 40 tons. This is crucial for areas exposed to vehicle traffic or intensive use. The round shape of the connection ensures tightness and easy installation. Cast iron is a material resistant to corrosion and mechanical damage – the manhole cover will last for years without the need for replacement.

Universal application in sewer systems

Manholes in which this cover is installed serve various functions:

• Non-access inspection chambers: allow access to the system using inspection or cleaning equipment.
• Access inspection chambers: provide personnel access to the sewer network.
• With a sediment trap (rainwater inlets): used in rainwater drainage and drainage.
• As tanks or sewage pumping stations: when using "blind" risers.

Thanks to this, the manhole cover finds application both in residential and industrial construction, as well as in urban infrastructure.
