Color tempering steel strips is a very interesting process, but it is difficult to master. The satisfaction is even greater when such colors are achieved in production. During the tempering process, an oxidation layer forms on the metal, which not only provides some rust protection but is often used for aesthetic purposes.

The band steel produced in the image is made for the band saw industry. The tempering color is used to distinguish between different types of band saw blades (wood, metal, etc.). It’s quite fascinating!
