Compression springs have a unique design which means that their compressed helix shape allows them to resist compressive forces.
Applying a heavy load to the compression spring forces it to compress and condense, the wire spaces then reduce in size until the spring’s wire touches, reaching the spring's maximum compressed length.
The coils provide an opposing force when compressed - storing the force until it is released. Find more about spring terminology.
Our sites feature the very latest advanced technologies in hot and cold coiling and we have recently invested over €1.25m euros in the world’s largest Wafios coiler.
Our investment in the most advanced spring manufacturing processes ensures our competitiveness across the compression springs industry.
Advanced CNC coiling and grinding machines deliver quality, accuracy, the best production run rates and efficiencies across an extensive wire range.

Our team of experts will consult at every key stage of the manufacturing process, collaborating with customers to ensure goals are met, targets are achieved and the product is dispatched within industry leading turnaround times at competitive prices.
There are four key components when considering a compression spring material - chemical composition, surface properties, tensile strength and size.
Compression spring material specifications cover a wide range from:
Our conditioning processes; which include heat treatment, shot peening and pre-setting are adapted according to specific compression spring material requirements.
We offer a range of different surface treatments for corrosion resistance or aesthetics.
We also hold one of the largest global stocks of chrome silicon and chrome vanadium wire anywhere in the world so that we can meet the needs of our customers and deliver as a preferred spring supplier.

Our design engineer's key role is to support you with your compression spring design. Solution providers, our innovative teams deliver exceptional engineering expertise, custom designing your spring to your specifications. To achieve the best results in developing your compression springs, our engineers ask a multitude of questions:
There are occasions where none of this is known, where customers are not sure of the parameters of their coil spring needs and that’s where our heavy duty compression spring engineers investigate further, discovering the customer’s compression spring purpose. In consultation with the customer, our coil spring engineers start looking at the history of the product, the story that has led to this point; piecing the jigsaw together to deliver the optimum spring for your needs. Compression spring design often goes through many cycles to guarantee the right design for the right purpose, often using prototypes and samples to test our designs. Our engineers are leaders in their field, ensuring the compression spring performance achieves maximum success for the customer.
A compression spring is used in any application that is required to store energy. Our heavy duty springs are widely used across the automotive, agriculture, fishing, mining, oil and gas, rail, energy and power generations, construction and motorsport industries. However, that’s not exclusive, our coil springs are used across many diverse sectors.
Springs are everywhere. As you read this, there will be dozens in the environment around you and you will very probably have encountered some of our heavy duty suspension springs on any transportation methods you used today. Air travel, land or sea, there will be a suspension spring at the heart of it and across many diverse sectors of the transport industry, even the vehicle parked at home contains car seat coil springs.
Compression springs manufactured from high-quality chrome silicon or chrome vanadium wire are the strongest springs. These steel alloys provide a chemical composition, surface property and tensile strength that when combined with spring size deliver outstandingly strong performance levels.
Springs do weaken under compression, over time. This is called relaxation and creep. Relaxation is when the stress level of the spring decreases over time at a constant deflection and thus loses force. Creep is when the spring loses length (increased deflection) at a constant force. This is time-dependent and can be predicted by our team.
