Concrete manhole cover round DO600 H115, CL.D400 (40T), ventilated, with sound-absorbing insert, locked, unpainted (raw) W0110-4031-1011-000

Robust infrastructure protection – concrete manhole cover class D400

This round, concrete manhole cover with a diameter of 600 mm and a height of 115 mm is a reliable solution for securing underground installations in areas exposed to vehicle traffic. Complying with the PN-EN 124-2 standard, it is classified in group 4 and class D400, meaning it can withstand a load of up to 40 tons – making it ideal for roads, driveways, pedestrian areas, hardened shoulders, and parking lots.

The manhole cover’s construction combines the durability of concrete with the strength of gray cast iron. The cover, filled with C35/45 concrete, is characterized by high resistance to freeze-thaw cycles (+R), guaranteeing long-term operation even in harsh weather conditions. Built-in positioners prevent the cover from rotating within the frame, ensuring stability and safety.

The lockable version further increases the level of security against unauthorized access. A damping insert reduces noise generated by passing vehicles, which is particularly important in urban areas. The raw, unpainted surface allows for easy adaptation of the manhole cover to its surroundings – it can be covered with paving stones or painted any color. It is important to remember that the manhole cover is designed for heavy traffic after locking.

• Strength: Class D400 provides resistance to loads up to 40 tons, guaranteeing safety and durability.
• Weather resistance: C35/45 concrete with +R additive provides resistance to freeze-thaw cycles.
• Security: Lockable design and cover positioners minimize the risk of theft and damage.
• Noise reduction: Damping insert reduces noise levels generated by vehicle traffic.
• Installation flexibility: Raw surface allows for adaptation to the surroundings and covering with paving stones.
• Application: Ideal for roads, parking lots, pedestrian areas, and other areas exposed to vehicle traffic.

The frame design is designed for easy installation and integration with the environment. The manhole cover is compatible with various types of surfaces and allows for aesthetic finishing of the surrounding space. Therefore, it is not only a protective element but also a functional element of urban or industrial infrastructure.
