Product Description
Our vented manhole covers are designed to provide both secure access and effective airflow or gas release from underground systems. Commonly used in telecommunications, drainage systems, and utility vaults, these covers help prevent pressure buildup while offering full structural support.
Available in ductile iron (GJS500-7) or grey iron (EN-GJL-250), the vented covers feature customizable slot or hole patterns that allow ventilation without compromising strength. Whether for urban sewer lines, cable tunnels, or industrial piping networks, our covers are built to meet EN124 load classes (B125–D400) and are available with optional gaskets or lock mechanisms.
We offer a variety of shapes (round/square), surface finishes (bitumen, epoxy, or galvanizing), and custom logos or city text engraving for localized requirements.
