A spring is a device, such as a coil of wire, that regains its original shape after compression or extension. Springs are manufactured out of wire, such as music wire, hard drawn wire, oil tempered wire and stainless steel. Utilized in numerous industrial applications, springs are characterized as being either compression, extension, torsion or wireform.

A compression spring is an open coil helical spring offering resistance when a load is applied against it. This load causes the coil to collapse at a specified rate of pounds per inch. Most compression springs are single diameter. Compression springs are normally manufactured out of round wire.

An extension spring is a closed coil helical spring containing energy to resist a pulling force. The pulling force causes the coils to separate at a given rate.

Torsion springs are closed coil helical springs with ends formed to provide torque when load is exerted on the ends. Depending on the application torsion springs can be designed to work in a clockwise or counter-clockwise rotation.

Wireform or flat springs are customized springs that are manufactured specifically to the shape and requirements supplied by the customer and do not necessarily take the shape of what is traditionally viewed as a spring.
