TS or Tigertec products utilize top-grade Cr-Si or Cr-V steel springs. Products of precise specifications can be manufactured by either hot rolling or cold rolling. The products have undergone heat treatment and shot peening treatment, which protect against deformation and ensure high fatigue endurance. After treated by powder coating, they are elegant-looking and rust-resistant. Coil springs are well-suited for cars, trains, motorcycles, and machines.
