La lámina galvanizada se refiere a la placa de acero recubierta con una capa de zinc. El galvanizado es un método antioxidante económico y eficaz que se utiliza a menudo. Aproximadamente la mitad de la producción mundial de zinc se utiliza en este proceso.

Las bobinas de acero galvanizado han pasado por un proceso químico para evitar que se corroan. El acero se recubre con capas de zinc porque el óxido no ataca este metal protector. Para innumerables aplicaciones al aire libre, marinas o industriales, el acero galvanizado es un componente de fabricación esencial. El método principal para hacer que el acero resista la corrosión es aleándolo con otro metal, el zinc. Cuando el acero se sumerge en zinc fundido, la reacción química une permanentemente el zinc al acero mediante el galvanizado. Por lo tanto, el zinc no es exactamente un sellador, como la pintura, porque no solo recubre el acero; en realidad se convierte permanentemente en parte de él.

Xiaoxian RuiYi / RAYIWELL MFG is professional manufacturer and supplier of Hot Dip Galvanized Steel Strip with high quality and reasonable price

For galvanized steel coils, the steel sheet is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
