The hermetic ductile iron road manhole cover h638_196 is a large-scale technical closing device, made of GJS-500-7 ductile iron according to the EN 1563 standard. Designed to withstand loads compliant with class B125, it is the ideal solution for covering wide inspection chambers in sidewalks, pedestrian areas, and parking lots. The product solves the problem of unpleasant fumes through an internal “U” seat which, when filled with sand or inert materials, guarantees an airtight odor seal. The square frame is designed for optimal anchoring thanks to an external perimeter flange equipped with holes for anchor bolts and reinforcing ribs, ensuring stability and perfect integration with the road surface.

User Benefits
Barrier against foul odors: The “U” profiling in the frame allows for the creation of an effective seal against the rise of bad smells from the underlying pipes.
Maximum stability: The continuous perimeter flange and reinforcing ribs uniformly distribute stresses, preventing foundation failure.
Safe surface: The anti-slip texture distributed on the cover ensures grip for pedestrians and cyclists, while facilitating rainwater runoff.
Guided maneuvers: The internal rounded corner ensures the unique insertion of the cover into the frame, avoiding positioning errors during inspections.
Protected opening: The closed-bottom slots prevent debris accumulation inside the lifting points, facilitating the use of dedicated keys.
Scope of application
This manhole cover is intended for contexts requiring wide inspection access (900x900 mm) for the maintenance of sewage, water, or technological networks. It finds its ideal placement in squares, sidewalks, bicycle paths and private parking areas where transit is limited to light vehicles. Thanks to its dimensions and B125 certification, it is suitable for civil and urban construction where a robust and perfectly level closure is necessary.
Why Choose It
The h638_196 model is the correct choice when a maximized net clear opening is required combined with the strength of certified ductile iron. It is preferable to other solutions when odor tightness and the mechanical stability of the anchoring (via anchor bolts) are essential requirements for the client. It represents a long-lasting investment for infrastructures that require high safety standards and reduced maintenance over time.
FAQ
What is the advantage of GJS-500-7 ductile iron compared to traditional cast iron?
Ductile iron offers superior mechanical strength and ductility compared to gray iron, allowing the production of lighter manhole covers for the same supported load, reducing the risk of brittle fractures under stress.
Is it possible to customize the cover with the name of the contracting authority?
Yes, the cover has a space specifically designed for the insertion of any identifying inscriptions or logos, allowing customization for public authorities or network service managers.
How is the indicated odor tightness achieved?
Odor tightness is achieved by filling the internal “U” seat of the frame with sand, grease, or equivalent materials. Once the cover is inserted, this material creates a seal that physically blocks the passage of sewer gases.
