Round concrete manhole cover DO600 H115, CL.D400 (40T), ventilated, with sound-absorbing insert, painted W0110-4031-1110-000

Concrete manholes – durability and safety on the road

This round concrete manhole cover DO600 with a height of 115 mm, class D400, is a reliable solution for use in road traffic. Designed for installation in roadways, pedestrian and traffic areas, hardened shoulders and parking lots, it can withstand loads up to 40 tons. The manhole design is intended for intensive use and easy integration with the surroundings – it can be covered with paving stones.

This manhole is ventilated, which prevents the accumulation of gases underground. It is also equipped with a damping insert that reduces noise generated by passing vehicles – this is particularly important in built-up areas. The painted finish provides corrosion resistance and an aesthetic appearance.

Durability and compliance with standards

Made of concrete and gray cast iron, the manhole meets the requirements of PN-EN 124-2 Group 4 class D400. This means that it has passed rigorous strength tests and is adapted to work in difficult atmospheric conditions and under heavy load. The manhole cover filled with C35/45 concrete class with +R additive ensures resistance to freeze-thaw cycles. Positioners prevent the cover from rotating in the housing, increasing safety.

It is worth mentioning that Koneckie Zakłady Odlewnicze S.A., the manufacturer of this manhole, holds a certificate of conformity issued by the Łukasiewicz Research Network - Krakow Institute of Technology (PCA – AC 030), certificate number 030-UWB-013/23. This confirms the high quality of the product and compliance with industry standards.
