Tension Springs

To ensure high quality tension springs, the brandgroup use the entire range of materials starting from cold drawn and patented spring steels and stainless steels up to highest-strength oil-tempered valve spring wires. Tension springs are fully automated manufactured with a wire strength of up to 6.50 mm and semi-automated up to 12.00 mm. We are your first choice, especially in the manufacturing of special forms and eyelets.
