Hard drawn shaped spring wire

Create stronger and more compact springs with Bekaert’s hard drawn shaped wire. By using square or rectangular wires, you can achieve springs that are stronger than traditional round wires and yet feature the same product properties and design. Alternatively, you can also produce lighter and smaller springs with comparable spring loadings as round wire.

Smooth production. High performance.

Production benefits

Smooth coiling

Bekaert hard drawn shaped wire consists of unalloyed, patented high-carbon wire that supports the production of highly dynamic springs. Thanks to a high level of process control, the wires feature very consistent edge radii, which prevent cracking at surface stress point and contribute to a longer fatigue-life. The smooth corner edges and stable dimensions of the wire enable a smooth coiling process.

More design flexibility

Due to different geometrical force distribution, shaped wire obtains higher stiffness values than round wire. As a result, these wires accommodate greater design flexibility to operate in compact spaces and enable the production of springs with optimal fill factors.

Prolonged service life

Industry benefits

Depending on the environment in which the spring is used, additional protection is needed. To avoid post-coating, it is possible to pre-coat the wire with Bezinal® XC if your design allows it. This advanced zinc aluminum coating of our own design provides superior long-term corrosion resistance in some of the most demanding spring applications.
