    vlamverzinkenThe fire galvanising or metallisation consists of covering the steel by a variable zinc- aluminium protection layer. The metallisation process with zinc or a zinc-aluminium alloy consists in melting the zinc material, under the form of a wire with the aid of a flame-gun and compressed air and spraying on the surface area to be treated. The metallisation process is always preceded by the irradiation of the steel surface in order to remove every trace of rust or dirt in order to attain the degree of purity of the metal surface area equivalent to the SA2.5-Sa3 norm on the one hand, and on the other, to arrive at a degree of roughness that is necessary for the doing of the metallization.
