The hot dipping process consists of passing the steel through a bath of molten zinc, while the electro-galvanizing process consists of the application of zinc through electrolytic disposition. The result is a layer of zinc tightly adhering to the base metal through an iron-zinc bonding layer. Our hot dipped galvanized products are manufactured to ASTM A653 specifications.

L'acer galvanitzat és un metall recobert-calent que ofereix als clients una millor resistència als ambients corrosius.
To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.
