Technically, BIO Stefan trash bin boxes are hot-dip galvanized and then coated. But what does that mean?
In hot-dip galvanizing, the base material made of steel is dipped into a molten zinc bath (approx. 450°C). After dripping off, a more or less thin zinc layer remains as a coating. This forms both an active and a passive corrosion protection: the thin layer protects the base metal from moisture (passive) and additionally acts as a sacrificial anode (active). The steel beneath the zinc layer is protected from corrosion as long as the zinc is completely consumed. The zinc layer is bright and shiny when fresh. Over time, it forms a patina due to corrosion, which makes the appearance darker and matte.
So why don't the boxes look like the usual galvanized steel sheet?
Even hot-dip galvanized objects can be coated with paint. To ensure good adhesion, a primer (adhesion promoter) is usually applied beforehand. The RAL 7016 color tone in which all BIO Stefan products are made adapts to almost any situation and constellation and guarantees a timeless aesthetic look for many years!
