Standard manhole covers

Inspection hatches are available in various designs and sizes. They are widely used in industrial and public facilities, such as shops, exhibition halls, restaurants, workshops, warehouses, car parks, streets and other places where access to underfloor installations is required.

The basic filling for the manhole cover is C35/45 concrete and a steel plate: smooth or grooved. Alternative fillings include floor tiles, resin and paving stones.

The manhole covers are made of stainless steel with a thickness of 2 mm. This allows them to be used in places with increased sanitary requirements.
