Carbon Steel Coil Springs, also known as torsion springs or helical springs, and compression springs, are utilized in various mechanical devices from car shocks to watches. The springs store energy and then release it to absorb shock as well as keep up a force between two contacting surfaces. These are made up of top-grade carbon steel and black color coating material in thickness of 3mm with developed technologies that guarantee excellent oxidation resistance, and long life. Moreover, Carbon Steel Coil Springs can be bought at negotiable prices.
