Characteristics of galvanized square pipe

The protective effect of galvanizing is more powerful, and its corrosion resistance is also better. The entire structure is composed of zinc, forming a dense quaternary crystal. This crystal forms a strong barrier on the surface of the steel plate, effectively preventing the penetration of corrosion factors. Therefore, the corrosion resistance of galvanized mainly comes from the barrier layer protection function of zinc element.

When the zinc coating is used as a sacrificial protection in the cutting corners, scratches, and scratches of the coating, the zinc element forms an insoluble oxide layer, which plays a powerful barrier protection function. This protective layer can not only prevent the corrosion factor from further eroding the steel plate, but also form a new protective layer in the damaged part and extend the service life of the steel plate.

The protective effect and corrosion resistance of the zinc coating benefit from the excellent properties of the zinc element. Zinc is a reactive metal that readily reacts with oxygen to form stable compounds that form a dense protective film. This protective film can not only effectively prevent the erosion of external substances on the steel plate, but also prevent the oxidation of the internal metal.

In addition, the zinc element also has good ductility and plasticity, so that the galvanized layer can be closely bonded to the surface of the steel plate to form a uniform and continuous protective layer. The thickness and quality of this protective layer directly affect the protective effect and durability of the galvanized layer.

In general, galvanized as a commonly used anti-corrosion technology, through the excellent performance of zinc and unique protection mechanism, provides a strong protective effect and corrosion resistance for steel plates. Whether in industrial production or daily life, the application of galvanized has been widely recognized and applied.
