Range A&B - Music wire

This category consists of two different series. Due to differing dimensions, the two series complement each other very well. We have therefore opted to collect them together into one. Series A is a European standard, while series B is an American series. This category is also available in stainless steel. Please note that stainless steel springs are 10% weaker than the corresponding springs in piano wire.

Range C - galvanized wire

The C series is a small series of springs in electrogalvanised wire. Although it is a small series, it is a good complement to series A & B. The series is also produced in stainless steel wire. The dimensions are the same for electrogalvanised and stainless steel, the only difference being the quality of the wire and the force. The stainless steel springs are approximately 10% weaker than the galvanised ones.

Range D - music wire

This series is available in three different lengths: 300mm, 500mm and 1,000mm. These springs are mainly used for testing – you can cut the springs to the desired length and then create loops. The springs are also available in stainless steel wire.

Please note that these springs do not have loops.
