Round concrete manhole cover DO600 H150, CL.D400 (40T), with sound-dampening insert, painted W0110-4012-1110-000

Robust infrastructure protection – concrete manhole cover class D400

This round concrete manhole cover with a diameter of 600 mm and a height of 150 mm is a reliable solution for securing underground infrastructure elements in areas with high traffic. Compliant with PN-EN 124-2, classified in group 4 and class D400, it can withstand a load of up to 40 tons – ideal for use on roads, driveways, pedestrian areas, hardened shoulders and parking lots.

The construction of the manhole cover is designed for durability and functionality. Made of gray cast iron, with a cover filled with C35/45 concrete class with increased resistance to freeze-thaw cycles (+R), it provides long-term protection against mechanical damage and weathering. Built-in positioners prevent the cover from rotating in the body, increasing safety.

An additional advantage of this model is the presence of a damping insert, which reduces noise during vehicle passage – particularly important in built-up areas. The painted surface provides additional protection against corrosion and improves aesthetics. The body design also allows it to be faced with paving stones, allowing the manhole cover to be harmoniously integrated into the surroundings.
