Materials

The following list exemplarily shows DIN and special materials generally processed by us. Since we stock several hundred tons of spring steel in our material store, we are able to deliver at short notice. In case you need compression springs, torsion springs, bent wire parts or rings made from other than the mentioned materials please contact us.
