The most common type of spring is a Coil Spring or Helical Spring, used to store mechanical energy and subsequently release it. These Coil Springs can be closewoundor open-wound and are made of hardened steel. The most common types are: Compression, Extension and Torsion

COMPRESSION SPRINGS can be found in ballpoint pens and valve assemblies as well as thousands of other places. When you put a load on the spring, makingit shorter, it pushes back against the load and tries to get back to its original length. Compression Springs may be cylindrical, conical, tapered, concave or convex inshape. The changing of spring ends, direction of the helix, material and finish allows a compression spring to meet a wide variety of special industrial needs; they arethe most common spring configuration and are usually placed over a rod or fitted inside a hole.

There are four basic types of compression spring ends, affecting the solid height, free length and other characteristics of the spring:

Open Ends, Not Ground: the ends of a compression spring are opened with a constant pitch for each coilOpen and Ground End: the ends of the spring are open and ground creating a flat surface
Square or Closed Ends (SQ): the ends of the spring are closed so that the end coils touch
Square (Closed) and Ground Ends (SG): the ends of the spring are closed so that the end coils touch & the end is ground to provide a flat plane

In a machined torsion spring, a pure couple can provide the moment. A pure couple can come from double tangs (external, internal and longitudinal), slots, splines (internal and external) and bolt circle configurations. One can also resolve the moment by an integral torque restraint on the coil side.

Open end coil springs feature a continuous pitch, extending to the end. Often called tangential coil springs, they are used in applications where the spring needs to rest on a surface, such as in automotive settings. For an open end coil spring to be functional, it must have a designated seat to support it.

Maintaining different types of iron wire is essential for ensuring their longevity and effectiveness. By conducting regular inspections, cleaning the wires, and applying protective coatings, you can significantly extend their lifespan and maintain their performance. Proper storage and preventive measures are also critical in protecting these wires from environmental damage. Through diligent maintenance, you can maximize the utility of your iron wire and avoid the costs associated with premature replacement.

In addition to providing support, grey garden wire can also be used for securing plant stems and branches. As plants mature, they can become top-heavy, and the weight of fruit or flowers may cause them to bend or break. Wrapping grey wire gently around the stems and securing them to a stake can help maintain the plant's structure without causing damage.

Trampolines
The trampoline utilizes hundreds of hook-ended extension or tension springs by attaching the trampoline base material to the metal frame. The springs secure the base in place and provide it with the flexibility and bounce. The greater the number of springs used, the greater the bounce.
