The supports are subject to electrolytic white galvanizing surface treatment.
During this process, the material to be treated is first adequately prepared (pre-degreased, pickled, and degreased) and immediately after it is soaked in an electrolytic solution containing zinc salts. Finally, a dc crossing occurs between the piece and the solution that deposit the metallic zinc on the surface of the piece itself.
Hot galvanizing ensures a complete protective coating and maximum protection against corrosion resistance.
The treatment involves soaking the previously treated steel components in a melted zinc bath at a temperature of 450 ° C. This starts a reaction of the metal that inextricably links steel and zinc generating on the steel surface a layer of pure zinc.
The soaking treatment allows the coating of the components inside, outside and even in inaccessible points. The result is a shock-resistant surface, extremely resistant to corrosion and strong, that lasts over time.
