The properties of tension springs
Tension springs are often used in lever-based mechanisms such as garage doors and are one of the most popular spring types. They are frequently used to provide return force to components that extend in an actuated position.
 What are tension springs?
Tension springs are archetypal, tightly-wound springs commonly referred to as ‘extension springs’ and are designed to operate with tension. The spring attaches at both ends to other components, and when the components move apart, the spring attempts to bring the components together again by reverting to its original shape.
 How are tension springs made?
Even though tension springs differ from compression springs, they are usually made from similar materials including copper, titanium and steel. Steel is the most durable of these, and there are different types of steel used, such as; stainless, cold rolled and alloy steel.
The process of making tension springs involves highly-advanced, hot and cold coiling procedures.
The distinguishing feature that sets tension springs apart from other types of springs is the tightness of their coils. Compression springs are commonly a looser type of spring compared to tension springs.
The design of the tightly-wound coil springs is essential in enabling the spring to stretch. The manufacturing process is important in ensuring the design of the springs can hold the components together.
 Common uses of tension springs
- Construction components.
- Automotive interiors and exteriors
- Washing devices
- Farm machinery
