Concrete manhole cover round DO600 H150, CL.D400 (40T), with sound-absorbing insert, unpainted (raw) W0110-4012-1010-000

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. Made of durable concrete and gray cast iron, it meets the PN-EN 124-2 Group 4, class D400 standard, which guarantees resistance to loads up to 40 tons. It is suitable for use on road pavements, pedestrian and traffic routes, and in parking lots.

Design and application

The manhole cover is designed for intensive use. The cover filled with C35/45 concrete class with +R additive ensures high resistance to freezing and thawing, which is particularly important in variable weather conditions. Built-in positioners prevent the cover from rotating in the body, increasing safety. In addition, the body design allows it to be faced with paving stones, allowing for aesthetic integration with the surroundings. A damping insert reduces noise during vehicle passage.

Key features and benefits

• Strength: Load class D400 provides resistance to high loads – ideal for areas with high traffic volume.

• Weather resistance: C35/45 concrete class with +R additive guarantees durability even in harsh weather conditions.

• Safety: Positioners prevent the cover from shifting, and optional locking (available in other versions) further secures the manhole cover against unauthorized access.

• Aesthetics: The possibility of facing with paving stones allows for harmonious integration of the manhole cover into the surroundings.

• Noise reduction: The damping insert minimizes sounds generated by vehicle traffic.

• Possibility of personalization: There is an option to place a customer's design (logo) on the cover, which increases brand recognition or identifies the manhole cover as an element of specific infrastructure.

• Raw material: Unpainted surface (raw concrete) ensures durability and eliminates the need for paint coating maintenance.
