Even if you weren't sure of the specific name, you've all encountered extension springs previously. The ability to give resistance to a more significant force to modify tension is provided by these coiled wire springs, which have two sides to make it simple to link them to another component.

You can accommodate numerous applications for extension springs through customization. They are helpful small components with many applications if given the necessary design features.


Typical Applications for Extension Springs

You can design extension springs with various loops or hook ends for particular tasks. In addition to rectangular endpoints and teardrop-shaped endings, extension spring ends come with threaded inserts, crossover center loops, hooks, expanded eyes, and reduced eyes.

For customized extension spring functions and fits, alter the hook length and the separation between the spring body. You can use extension springs for various things in daily life, from the vehicles that transport you daily to the agricultural equipment that generates food.

There is always a requirement for an extension of some kind because extension springs have various sizes and forms with multiple hooks and eyes to latch onto both sides. The springs are broadly applied in the automobile sector, farm equipment, electronics, toys, and a wide variety of other products.



A lot of toys in the past used extension springs. You can use the springs in various toys, particularly those with a shooting or throwing component. However, the small springs and the objects they discharged were considered dangerous for children. Pinball machines and wind-up toys are two examples of incredibly secure and well-liked toys that use extension springs.

Washing Machines


When it comes to mechanical extension spring uses, a washing machine is perhaps among the last items you might think of, but they play a crucial role in the equipment. Your washing machine's drum starts spinning as you turn it on, agitating the clothing and starting the washing cycle. The spinning drum would beat against the walls of the machine without extension springs, tossing it around the room and creating loud noise as you do your clothes.

Farm Machinery


Due to the force and strength needed to pull, farm machinery uses heavy-duty extension springs. Although "farm machinery" is used broadly, many vehicles utilized on farms will use extension springs. You can use the extension spring to its fullest extent on everything from tractors to combined harvesters. 

People plough fields, move heavy items around the farm, or even trailers tow large goods. While machinery often uses hook or loop-style heavy-duty extension springs, numerous varieties are available. If they notice any problems, like deflated tires or rusted springs, it's time for a change. Farm equipment needs to be updated and safe at all times.

Springs in Trampolines


As a result of the usage of extension springs, trampolines are particularly well-liked. They powerfully illustrate how you can use extension springs in the garden. The trampoline's base is fastened to the steel frame by thousands of hook-end extension springs. It is more flexible because of the number of springs used to hold the ground.

For instance, the trampoline's rebound wouldn't be as agile if it had half the amount of springs and solid connectors. The trampoline's springs are in their coiled state while at rest. 

The trampoline's bouncy quality is caused by the abundance of extension springs at its bottom. Thanks to these extension springs, people can jump without exertion by bouncing back to the trampoline. The trampoline bounces more when it has additional extension springs.



A pram is a common means of transportation for small infants and kids. The pram, or rather perambulator initially named, has been made employing extension springs from its inception: the first Coach Where the expensive strollers were built, Silver Cross. As you rock the baby to sleep in the pram, the springs create the suspension effect.

The springs increased the pram's flexibility and made it easier to maneuver. It's a somewhat big pram, but it was widely used until recently. It isn't easy to get in some of the front doors due to the tiny houses being built today together with pram size.

The first suspension strollers served as the model for all subsequent models. The suspension impact is still present in most modern strollers but to a lesser extent.

Garage Doors


The garage doors also feature extension springs. They support lowering and raising the door since they connect the edges of the doors. Those extension springs reduce the potential force needed to lift and close such doors.



The Chest Expander is the piece of exercise gear most often found with extension springs. A line of extension springs lined up side by side and attached to a metal or plastic handle at each end make up the chest expander's mechanism.

When using the chest expander, draw both handles simultaneously to extend the springs to the desired length. As you let go of the strain, the springs will exert all their force to return to their initial position. It functions by exerting energy on the muscles to pull and resist.

Medical equipment


The functioning of springs has been a staple of medicine for millennia. You can employ extension springs in a wide range of medical equipment. Some of these tools include stretchers, operating lights, and several small handheld devices.

Take away


If you need extension springs for your industry's purposes, you should buy them from professionals. Extension springs store potential energy and provide resistance since they have an object attached to each end. The initial tension of the spring controls how tightly the wind its coils are.

Extension springs differ by extended length, body length, maximum load, hook/loop length, and much more in addition to tension. Additionally, you can choose the loop's location, the distance between its ends, the finish, the material, and a lot more.

You can construct a spring-appropriate for various applications and environments by modifying its multiple properties. Some skilled engineers from Foshan GL Metal can assist you in choosing the right specs for any spring purchase. Contact their staffs to get started designing a set of springs right away.
