Descripción del producto

A variant of strip galvanizing is the so-called zinc alloy hot dip, in which zinc alloy coatings are applied to the steel strip. These consist of zinc aluminum (ZA), zinc magnesium (ZM) or zinc aluminum magnesium (ZAM). The usual layer thickness of these coatings is up to *5 microns. THE process sequence in hot dip coating with zinc alloys largely corresponds to hot dip coating with zinc and is described in " Galvanizing strips (pure zinc coatings) ". Also with zinc alloys, melt-refined steel strip is a so-called semi-finished product, which is a precursor, which is further processed by galvanizing by stamping, stamping and cutting. As a result, the protective layer of zinc is destroyed at the cutting and punching edges.
