1. A process for producing profiles from metal, the process comprising:

  • shaping a metallic strip material with a shaping-hardening device, in which the strip material is shaped into a profile by a profiling roller;

    hardening the profile during the shaping at least in certain regions;

    emerging portions of the profile continuously from the shaping-hardening device providing a shape hardened profile;

    cleaning the shape hardened profile;

    heating a temperature of the shape hardened profile to a range between 25°

    C. and 300°

    C.; and

    subsequent to the temperature adjusting, coating only a first portion of the shape hardened profile with a protective layer so that the shape hardened profile has both coated portions and uncoated portions, wherein the coated first portion of the shape hardened profile is at a lower risk of corrosion as compared to the uncoated portions.
