Abstract
The present invention provides a process for manufacturing a metal strip having a metallic corrosion protection coating. The process includes making the metal strip pass through a bath of molten metal having between 2 and 8 wt. % aluminum, 0 to 5 wt. % magnesium and up to 0.3 wt. % addition elements, the balance being zinc and inevitable impurities. The bath is maintained at a temperature between 350 and 700° C. Nozzles wipe the coated metal strip spraying a gas on either side of the strip. The coating is cooled in a controlled manner until it has completely solidified. A metal strip and a metal part obtained by deformation of this strip are also provided.
