Round concrete manhole cover DO600 H150, CL.D400 (40T), ventilated, with sound-absorbing insert, painted W0110-4032-1110-000

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 high-traffic areas. It meets the requirements of PN-EN 124-2 standard, class D400, which means it can withstand a load of up to 40 tons – making it ideal for roads, driveways, parking lots and pedestrian/vehicle routes.

The manhole cover design is focused on durability and functionality. Made of concrete and gray cast iron, it provides resistance to mechanical damage and corrosion. The cover filled with C35/45 concrete class is characterized by high resistance to freeze-thaw cycles (+R), which guarantees long-term operation even in harsh weather conditions. Built-in positioners prevent the cover from rotating in the frame, increasing safety.

Additionally, the manhole cover is equipped with a noise-reducing insert, which reduces noise generated by passing vehicles. The painted surface provides an aesthetic appearance and additional protection against external factors. The ventilated design supports air circulation under the cover. The frame construction allows for easy paving with paving stones, allowing the manhole cover to be harmoniously integrated into the surroundings.

The D400 class manhole cover is characterized by high strength, making it suitable for high traffic volume (up to 40 tons). Made of concrete and gray cast iron, it ensures durability and resistance to mechanical damage and corrosion. C35/45 concrete class with freeze-thaw resistance (+R) guarantees resistance to adverse weather conditions. Positioners preventing the cover from rotating and the possibility of installing bolts (optional) increase safety. The noise-reducing insert reduces noise, and the painted surface provides an aesthetic appearance and additional protection against external factors. The construction adapted to paving with paving stones facilitates installation and integration with the surroundings.

It is worth remembering that this model of manhole cover is ventilated, which is particularly important in places where moisture or gases may accumulate. It is a universal solution for both professionals involved in the construction and modernization of infrastructure and for end customers looking for reliable protection of underground installations.
