In order to protect steel screws, nuts, washers and nails, surfaces are finished using electroplating. This process consists of three process stages (pre-treatment, metal separation and post-treatment) and takes approx. 3.5 hours. During the course of this, the electroplating application only takes approx. 90 minutes.
