Technically speaking, 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?
