Features:
1. No Deformation or Fatigue under normal loads. 
2. High Energy Storage Capacity. 
3. Long Service Life. 
4. Stock keeping is minimized as the individual spring sizes can be combined universally. 
5. Space Saving. 
6. Largely Self-damping, giving good shock absorption and energy dissipation. 
7. Efficient use of space and high spring force with small deflections. 
8. Adaptable to stacking in numerous configurations. 
9. Combination use as a modular spring element. 
10. Low Maintenance cost.
11. Greater Security
