Spring steel strip is used to build springs for a great variety of purposes. Below especially the cold rolled (carbon as well as stainless) spring steel strip will be described in detail. The most common production width of spring steel strip is about 300 mm (11.811 inches). As a matter of course spring steel strip can be slit or cut to length (sheets). We supply a very wide range of high carbon and alloys, covering the most stringent industrial requirements. We have also developed a unique know-how in the design of custom solutions for special applications.
