Specifications Of Our Extension Springs
The initial tension applied dictates how close these coils are and by controlling this initial tension, it is possible to customise the spring to cater to specific load requirements. The coiled design of a spring is what provides the strength and elasticity. A tension spring is tightly wound and when in a rest state, it remains coiled. We include interfaces such as eyes, hooks or loops at both ends to facilitate attachment to other components.
We offer a variety of custom specifications so you can order the suitable extension spring for your specific needs. From different wire sizes, materials used and even finishes, you can ensure that you are receiving the best possible service and product from Springs.

What are extension springs?
Tension springs, or extension springs, are one of the most commonly known springs in the spring manufacturing industry. They are tightly wound coils that are designed to operate with tension force. Tension springs are helical coiled springs designed to bring components together, or for attachment purposes – using loops and hooks – rather than to keep them apart. A high-tension spring works by absorbing energy and storing it and when tension is applied, its energy creates a resistance to counter the pulling force.
Trusted custom extension springs manufacturer
Custom Spring Manufacturing is an ISO 9001:2015-certified fabricator of metal springs for industrial applications. We manufactured springs from circular, rectangular or square material which offers resistance to a force applied axially whose free length extends in the direction of an applied load.
The ability to produce custom extension springs that meet your performance requirements is what sets us apart.
