• Odor Reduction: The "U" groove system blocks the rise of unpleasant sewer gases and fumes, improving hygiene and comfort in residential or commercial areas.
• High Mechanical Resistance: Ductile iron offers significantly higher elasticity and impact resistance than traditional grey iron, reducing the risk of sudden cracking or breakage to zero.
• Optimized Pedestrian Safety: The geometric non-slip texture ensures excellent grip, minimizing the risk of accidental falls in case of rain, frost, or humidity.
• Stable and Silent Interlocking: The anti-sliding design keeps the cover perfectly secured in its seat, reducing micro-movements and noise during passage.
• Infrastructure Customization: The smooth space on the cover allows for the insertion of logos or lettering upon request, facilitating the mapping and recognition of networks by utility companies or service providers.

The h638_158 model is perfectly suited for urban and private contexts with moderate traffic. It is the preferred choice for sidewalks, pedestrian squares, condominium courtyards, cycle paths and parking areas for cars. Thanks to its clear opening of 70x70 cm, it allows easy access for routine maintenance operations on hydraulic, electrical, or telecommunications inspection chambers.

Choosing this manhole cover means investing in a modern, safe and extremely durable road component. With a balanced weight of 43.50 kg, it ensures optimal critical mass to remain stable in its seat without being excessively burdensome during manual inspections. It represents the best compromise for public administrations, installers and private individuals seeking a definitive solution against bad odors and debris infiltration, ensuring full compliance with European safety standards for urban furniture.

What is meant by B125 load class?

The B125 class, according to the European standard EN 124, certifies that the device is designed to withstand a test load of 125 kN (approximately 12.5 tons). It is suitable for pedestrian areas, sidewalks and parking lots for cars only.

How is the "U" seat used to eliminate odors?

Before placing the cover, simply fill the "U" groove of the frame with fine sand, thick grease or an equivalent insulating material. This creates a continuous mechanical seal that prevents sewer gases from rising to the surface.

Can the cover be lifted with standard equipment?

Yes, the cover is equipped with special lifting slots shaped to accommodate standard hooks or keys commonly supplied to maintenance personnel.

Is it suitable for the passage of vans or garbage trucks?

No. While it tolerates the occasional transit of light vehicles or cars in parking areas, for roads subject to frequent passage of heavy vehicles or garbage trucks, it is mandatory to install higher-class manhole covers such as C250 or D400.
