Hot-dip galvanization

The core of the process. Materials are put in the zinc bath, to a temperature ranging from 430-460 °C, at which point the zinc is in a liquid state during the time required for the creation of an iron-zinc alloy coating on the items. Galvanization quality depends on the zinc purity in the pool: this must never go under the level defined by UNI EN ISO 1179 norms.
