The shape of compression spring is: cylindrical, conical, convex and concave and a small number of non-circular, cylindrical compression spring is one of our common spring types, they have a very wide range of applications in automobiles, mechanical equipment, seals, valves, daily necessities, medical breathing equipment, medical mobile equipment, hand tools, home care equipment and so on.

 

Our springs are made from high quality material and shot-peened to yield a higher tensile strength and longer life. The spring is then entirely compressed under hydraulic pressure to preset the coil which dramatically reduces any chance of fatigue or sag. Furthermore, a baked on powder coating is applied for continued protection against corrosion both on and off the road.

Aside from these features, each coil spring design has endured a cycle test to assure the very best in quality.
