Why coat?
The need to coat a spring can have many causes. The main purpose of the coating is to protect against corrosion, but there may also be optical reasons. For example, color distinctions serve as an assembly aid, a certain color increases the recognition value or simply to improve the appearance of visible springs.
RÖHRS looks for the best possible solution together with the customer and recommends the appropriate procedure.
Common are:
- Zn-Al lamella Coating to increase corrosion protection
- Varnishing for individual coloring
- Chromating for optical improvement
