We work with: High-carbon steel (Grade 65Mn/70Mn) – most common for industrial use Stainless steel (301/302/304/316) – corrosion resistance Alloy steel (50CrV/55CrSi/60Si2Mn) – high-temperature resistance Custom materials (available upon request)

Compression springs are characterized by their unique helical (or corkscrew-like) wire structure. This specific shape enables them to absorb compressive loads—when the helix is pressed, the spring shortens in length while generating resistance against compressive forces.

When compressed, these springs efficiently store substantial amounts of mechanical energy. Once the compressive forces acting on the helical coil are removed, this stored energy is released.
