Minimizing the risk of human failure within the assembly process through giving different colours to different products, improving the appearance of the spring or Branding are just some examples...
RÖHRS will investigate about the best solution for the customer needs and will design as well as produce accordingly. Some approved methods are:
- Zn-Al-Lamelle Coating for corrosion resistance
- Varnishing for individual colours
