What are the strongest 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.

Do springs weaken under compression?

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.

What are heavy-duty compression springs?

Heavy-duty compression springs are the strongest of the coil spring range.

Designed and manufactured to manage the extreme demands of the environment they perform in, our design process evaluates the stress, temperature and corrosive risks endured by the product, to guarantee a highly engineered heavy-duty compression spring delivering on quality, endurance and accuracy.

We supply heavy-duty compression springs for numerous industries including renewables, automotive, mining, rail, construction, energy, motorsport and many more.

How do compression springs work?

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.

Types of compression springs

There are many types of compression springs and our hot and cold coil spring manufacturing specialists are experts in the field of:

Straight coil springs

The most popular compression spring with wire coiled at the same diameter throughout the length. Also known as parallel springs.

Convex springs

These compression springs have larger diameters in the middle than at the ends. These can also be called barrel springs.

Concave springs

With an hour glass shape with a smaller diameter coil in the middle, this symmetry allows the coil spring to be centrally located over a specific point.

Conical springs

Conical springs are also known as a tapered spring, these compression springs are coiled in increasing or decreasing outer diameters providing an almost cone spring shape.

Variable PITCH spring

A spring with varied coil spacing, delivering varying coil heights across the coil springs length.

Banana spring

Shaped as the name suggests and also called sideload springs, the shape counteracts lateral forces.
