Endless spiral

Endless spirals are pressed out of one piece. Please note that due to this process, the wall thickness in the area of the bore is double the thickness as on the outside. The standard length of the spiral spirals is approx. 3,000 mm and are available from stock in the following materials: S235JRG2 and stainless steel 1.4301 (grade 304), on left or right hand pitch. Custom-made products are available upon request.
