Material pre-treatment plays a decisive role in galvanising quality. Therefore, the “degreasing”, “pickling”, “rinsing” and “fluxing” procedures follow sophisticated and strict recipes, which are pre-programmed in the automatic plant control system in a far-sighted, structured and individual manner.
The gaseous emissions (hydrogen chloride – HCl) created in the encapsulated processing tanks are washed out of the atmosphere using special capture, extraction and high-tech waste air scrubbers. The HCl is then returned to the process tanks. As a result, the European directives with regard to exhaust air and flue gases are not only fulfilled, but also undercut.
The process tanks are made from polyethylene or polypropylene, whereby the choice of materials remains flexible. The tanks are encased in a steel corset.
