• Total Odor Reduction: The internal "U" perimeter seat acts as a sealing barrier against the escape of unpleasant gases and vapors from sewage networks, improving the healthiness of the surrounding environment.
• Robustness in a Compact Format: Despite weighing only 6.50 kg, the mechanical and elastic properties of GJS-500-7 ductile iron allow the manhole cover to withstand loads up to 25 tons without deforming or cracking.
• Automatic Safety Closure: The mechanical interlocking system with elastic appendages guarantees a stable and immediate coupling to the stop, preventing accidental removal or lifting of the lid.
• Pedestrian and Vehicular Safety: The anti-slip geometric reliefs distributed on the surface favor the rapid runoff of rainwater and prevent skidding or slipping even in wet conditions.
• Simple and Quick Inspection: The blind-bottom slots allow the insertion of a common lever or standard lifting keys, facilitating access by technicians without requiring complex instrumentation.

The h638_164 model is specifically indicated for covering junction boxes, water meters, telecommunications nodes, and small technological drains. It finds its ideal placement in public and private parking lots, commercial courtyards, condominium access lanes, residential areas, and street sidewalks subject to the frequent transit of cars and light commercial vehicles.

Choosing this manhole cover means opting for an **agile, ISO 9001 certified road component that fully responds to modern European regulations**. The reduced height of only 30 mm and the 30x30 cm layout facilitate installation even in the presence of reduced flooring thicknesses. It is the perfect investment for construction companies and municipalities looking for a durable and airtight product, capable of zeroing post-installation maintenance and problems related to urban bad odors.

What is meant by load-bearing class C250?

Class C250, according to the UNI EN 124 standard, certifies that the manhole cover is designed to withstand a test load of 250 kN (approximately 25 tons). It is the appropriate category for installation in the areas of drainage channels along the edges of sidewalks, squares, and parking lots for cars.

How is odor tightness configured with the "U" seat?

The "U" seat is a perimeter gap integrated into the frame. By filling this groove with fine sand or equivalent sealing materials before inserting the lid, a continuous blind joint is created that mechanically blocks the ascent of sewage fumes.

Is a special or proprietary key needed to open it?

No, the lid is designed to be easily lifted by inserting a common construction site lever (or a standard crowbar) inside the dedicated slots, optimizing the intervention times of technical teams.

Can the lid be customized with the logo of the Municipality or company?

Yes, on the upper surface of the lid there is a flat and smooth space specifically structured to host, upon request and for suitable order lots, engravings of logos, company brands, or identifying wording of the water or technological service.
