Hot-dip galvanizing is one of the most important procedures for corrosion-proofing steel. Once the steel strip has been coated in the over 450°-C zinc or zinc-aluminum bath, it is not only highly corrosion-proof, but also features exactly defined mechanical properties such as formability.

We supply process-optimized hot-dip galvanizing lines that make the grade with high speeds and zinc coatings to ultra-close thickness tolerances. Included here are air knives that automatically control and set the desired thickness of the zinc coating. Depending on the surface quality, air or nitrogen is used to remove the liquid zinc. It’s essential for the high precision of this process that the strip runs smoothly in the area of the air knives. Next in line is an exactly defined cooling process in the downstream air and water cooling section. At the end of the process, galvanized steel strip that meets the high quality demands of international markets leaves the production line.
