SPIRAL HOSES
The Spiral hoses are made with stainless steel galvanized tape or copper wound in a spiral with continuous sealing helical stapling
The external hemming gives the pipes considerable rigidity and resistance to crushing three times higher than that of a traditional calendered pipe.
Tubes can be made from a diameter of less than 80 mm, up to a maximum of 1400 mm. Our Spiro tubes were used for the construction of the foundations of the C metro in Rome, in the pipe is poured cement where inside passes the construction rod.
