Automatic line,Sand casting, ductile iron manhole covers D400
Frame
It is obtained from a single cast, its stability is guaranteed
through a double throat supporting area, creating a metal to metal
coupling thanks to the interposition of an EPDM gasket, this is
studied to obtain a watertight/waterproof sealing. Inside there is
also a special provision to host, if necessary, the glass
reinforced plate (GRP).
COVER
It is Round in Shape, it ensures a high stability due to a depth of
insertion over 50 mm, the EPDM gasket inserted in the throat, which
is located in the supporting area, and the locking system with 3
stainless steel screws. The opening process is obtained through the
insertion of specific handles in the blind holes of the surface.
All the covers are interchangeable. The top surface is antiskid and
it allows the complete flow of water.
