Product Description

Our compression springs range covers varies of lengths.  . Our products are  made in accordance with current DIN standards with  high  quality demands both in European  and American markets


Piano line dry terrain Piano line springs are recommended for use in dry surroundings. The material offers no protection against rust. Piano line springs are roughly 10 stronger than pristine sword springs. Electrogalvanised contraction springs are made from piano line, which is also electrogalvansed. This gives the contraction springs an seductive, candescent face. Electrogalvanisation only provides moderate erosion resistance, but if the spring is used in a sticky terrain, the service life will be dragged compared to the same spring made from piano line without face treatment.
Stainless steel wire: humid environment

Tempered steel wire: humid environment We recommend stainless steel wire springs for humid environments. Piano wire springs are 10 percent stronger than stainless steel springs.

We recommend springs made of a particular kind of stainless steel (AISI 316) if you plan to use them in environments where they will be contaminated by salt water or harsh chemicals. We do not keep these on hand, but if you ask, we can make them specifically for you. For more information, get in touch with us.

Jumps on cutting and testing

On the off chance that you are uncertain about the length/travel you want, we have springs in lengths of 300, 500 and 1,000 mm produced explicitly to be sliced to length and utilized for models and testing.
