BIO Stefan trash can linings: The hot dip galvanizing
Technically, BIO Stefan garbage can boxes are hot-dip galvanized and then coated. But what does that mean?
In hot-dip galvanizing, the steel base material is immersed in a molten zinc bath (approx. 450°C). After dripping off, a more or less thin zinc layer remains as a coating. This forms both active and passive corrosion protection: the thin layer protects the base metal from moisture (passive) and also acts as a sacrificial anode (active). The steel underneath the zinc coating is protected from corrosion until the zinc is completely consumed. The zinc coating is bright shiny when fresh. Over time, as a result of corrosion, it forms a patina, which makes the appearance darker and more matte.
So why don't the boxes look like galvanized sheet steel, as usual?
Hot-dip galvanized objects can also be coated with paint. In order for the paint to adhere well, an adhesion improver (primer) is usually applied beforehand. The color RAL 7016 in which all BIO Stefan are produced, adapts to virtually any situation and constellation and ensures a timeless aesthetic appearance, for many years!
