CONTINUOUS SPIRALS TYPE S
The “S” type spirals technologically represent the best of what the market can offer regarding quality, accuracy, sturdiness and durability. They are obtained through cold working by a patented process which reduces taper and increases the mechanical characteristics of the material.
MATERIALS USED
- Normal steel S235JR e P12.
- Stainless steel (Aisi 304, Aisi 316 and all the series 300).
CHARACTERISTICS
- Section of the slightly tapered blade.
- Accuracy in dimensions.
