...Spiral tubes are made from galvanized stainless steel or copper strip wound in a spiral with continuous helical stitching for a tight seal. The external raised stitching gives the pipes significant rigidity and crush resistance, three times greater than that of a traditional rolled tube. Tubes can be produced starting from a minimum diameter of Ø 80 mm, up to a maximum Ø of 1400 mm.
