Galvanized sheet is a steel sheet that has received a specific treatment consisting of hot galvanizing. As such, the steel is immersed in a zinc crucible so that the sheets are fully covered with this metal.
Sometimes, depending on the specific sheet, the immersion may have been carried out in a zinc-iron alloy. In any case, when carried out hot, it fully adheres to the steel, so steel and bath become inseparable. This is especially the case in the case of the zinc-iron alloy, which prevents chipping to a greater extent.
Therefore, it presents an inner sheet of steel that constitutes the thickness of the sheet, but also a zinc coating which gives it that characteristic galvanization. Thus, the steel is fully protected from contact with external and atmospheric agents.
