The single and double torsion spring tines for agricultural machinery that we manufacture are made of high tensile strength springs wire. They are produced according to standard 

We only use prime quality materials with proven tensile strength. Therefore, the main feature of these torsion spring tines is their fatigue resistance and flexibility to endure the whole work cycle.

On request, all the springs can be finished with epoxy powder coating or with black cataphoresis treatment after shot peening, when necessary.
