• Certified air-tightness: The "U" chamber allows the creation of a natural siphon that prevents the rising of unpleasant odors from the subsoil.
• Structural stability: The beveled perimeter flange and reinforcing ribs distribute loads onto the foundation, preventing road surface collapse.
• Pedestrian safety: The non-slip pattern guarantees grip even in wet conditions, reducing the risk of slipping.
• Precise installation: The beveled corner prevents cover positioning errors, speeding up maintenance operations.
• Material longevity: The use of ductile iron ensures a weight-to-strength ratio superior to grey iron, reducing mechanical wear.

This manhole cover represents the correct choice when the primary need is to combine mechanical resistance with the necessity of environmental isolation. It is the preferred solution compared to standard models in densely frequented residential or commercial contexts, where the elimination of miasmas is an essential requirement for public comfort. The ISO 9001:2015 certification of the production chain also guarantees traceability and compliance with the most stringent tender specifications.

The main use of this manhole cover concerns urban pavements and pedestrian areas where the presence of underground services (sewers, electrical or water networks) requires frequent access for inspection. It is ideal for installation in condominium courtyards, multi-storey private car parks or parking areas for cars, where class B125 guarantees maximum safety against light static and dynamic loads. Its shape also makes it suitable for historic urban furniture contexts, thanks to the formal cleanliness of the square frame.

What is the difference between a B125 and a C250 manhole cover?

The difference lies in the load capacity: class B125 is designed to support up to 125 kN (approx. 12.5 tons) and is limited to pavements and pedestrian areas, while class C250 is intended for roadsides and drainage channels along pavements, supporting higher loads.

Which regulations govern the production of this manhole cover?

The product is made of ductile iron according to the European standard EN 1563 and meets the design requirements established by the UNI EN 124 standard, which defines the resistance classes and test methods for gully tops and manhole tops.

How is the odor-proof seal achieved?

The seal is not mechanical but hydraulic/static: it is necessary to fill the "U" seat in the frame with fine sand or grease. Once the cover is inserted, its lower flange is immersed in the filling material, creating a physical barrier to fumes.
