Steel springs in brief
- high load bearing
- long service life
- normal to fast motion rhythm, ideal for jogging, walking, ski gymnastics, dynamic cardio training
- recommended for untrained ankle muscles and for rehabilitation of ankle, knee and hip joints
Generally steel springs get zinq plated to prevent corrosion. With just one severe disadvantage: Zinq makes the surface of the spring brittle and prone to breakage. Therefore Trimilin springs are sumitted to a special proceeding which renders zinq plating superfluous. At the same time it gives them their characteristic charcoal-grey colour. The long term stress tests show that it is all worth the effort. The longevity of the springs
improves significantly.
