Product Description

GALVANIZED SHEET

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.

CHARACTERISTICS OF GALVANIZED STEEL SHEET

1. Galvanized steel sheet is widely used in various environments, with long anti-corrosion life, and different anti-corrosion life in different environments.

2. Low processing cost, the anti-corrosion cost of galvanized steel sheet is lower than other paint coatings.

3. Durable, in suburban environment, standard galvanized anti-corrosion coating does not require maintenance and can be maintained for more than 50 years.

HOT-DIP GALVANIZING LAYER FORMATION PROCESS

The formation process of the hot-dip galvanizing layer is the process of forming an iron-zinc alloy between the iron matrix and the outermost pure zinc layer. During hot-dip galvanizing, an iron-zinc alloy layer is formed on the surface of the workpiece, making the iron and the pure zinc layer tightly combined.

When the iron workpiece is immersed in molten zinc, a solid solution (body core) of zinc and α iron is first formed on the interface. This is a crystal formed by zinc atoms dissolving in the matrix metal iron in the solid state. The two metal atoms are fused, and the attraction between the atoms is relatively small.
