With over 70 years of experience, European Springs is a trusted leader in custom and off-the-shelf tension spring manufacturing. From small-batch bespoke parts to high-volume stock supply, we deliver ISO 9001-certified springs built for lasting performance.
We offer both custom spring solutions in addition to stock extension springs, catering to a diverse range of needs. Depending on your specific needs, we can assist you in finding the perfect solution for your given application.
Often our customers have a specific spring application in mind that necessitates the design and manufacture of a bespoke solution. Through our tension spring design services, we offer unique solutions with specific design and material selection considerations.
Our experienced engineers utilise state-of-the-art CAD CAM systems to bring your ideas to life with precision and efficiency. Taking into account the environment, stresses, life-cycle requirements and many other factors, we can assist in the design of custom tension springs that are precisely optimised for their intended use. European Springs and Pressings is accredited with ISO 9001:2015, guaranteeing you quality springs throughout the manufacturing process.
As part of the internationally renowned Lesjöfors Group, we are also extension spring suppliers of stock spring solutions. Browse our full selection of wire springs in our spring catalogue, where you can find:
Unalloyed Steel Extension Springs (EN 10270-1-SH)
Stainless Steel Tension Springs (EN 10270-3-1.4310)
With decades of engineering expertise, we provide both off-the-shelf and fully customised tension springs, designed for demanding performance across every application. Using both hot and cold coiling methods, we create springs in wire sizes from 0.1mm to 26mm, in both steel and stainless steel, offering a wide range of end types including coiled loops, extended hooks, and screw-in features.
Our advanced CNC machinery and rigorous quality control ensure accuracy and reliability in every component we produce. Whether you need a small custom batch or a larger production run, our expert team is on-hand to deliver durable springs designed for consistent performance across a wide range of applications.
In addition to tension spring manufacturing, we offer a range of additional services to streamline your project requirements. From laser cutting for R&D testing to heat-treatment and assembly services, we provide end-to-end solutions to meet your needs.

Tension springs, alternatively known as extension springs or coil tension springs, are tightly wound coils engineered to function under tension force. Typically featuring loops or hooks at each end for attachment, these springs are designed to store and release energy when subjected to external forces.
These springs find widespread applications in various settings, from counterbalancing garage doors to farm machinery and trampolines. Their primary role is to harness external force, utilising the stored energy within the coil to draw components together, thus reverting to their original configuration. Due to their function, tension springs are tightly wound and closely coiled at rest.
Tension springs serve to connect two components, bringing them together when there’s a tendency for separation. When subjected to a load or force, the spring elongates to a specific length, absorbing energy and generating resistance against the pulling force. In their relaxed state, the coils of the spring are in contact with each other.
Upon separation of the components, typically from opposing directions, the spring strives to maintain cohesion, exhibiting spring action until the force is counteracted, allowing it to return to its original state.
Many high-tension springs are wound with initial tension, which is the force holding the spring coils compacted together. The measurement of initial tension represents the load required to overcome the internal force and initiate coil separation.
Tension springs find utility across a broad spectrum of industries, including:
We recommend replacing your tension springs once they have reached 10,000 repetitions. This is to ensure that the springs are not being overexerted, so your application can run reliably. Be sure to conduct regular checks on your springs to ensure they are working properly, to avoid spring failure.
Compression springs are designed to resist compression, they push back when a force is applied to them. Tension springs are designed to resist being stretched, they pull back to their original length when extended.
Here is an inclusive list of the main sectors and applications where Tension Springs improve designs and make a positive difference.
And even if we don’t have exactly the tool we need, European Springs’ in house technology enables us rapidly to design and make complex tools, allowing us to offer more competitive prices.
