Advantages of Galvanization

GALVANIZED

Hot-dip galvanizing is one of the most effective systems for protecting steel wire against the corrosion it experiences when exposed to the atmosphere, water and the ground. It consists of the formation of a coating by means of the application of zinc at 450 °C.

PROPERTIES

The coatings obtained by hot-dip galvanizing are constituted by layers of zinc-iron alloys, of which there are mainly three: “gamma”, “delta” and “zeta”. There is a further outer layer of practically pure zinc (“eta” phase), which is formed by the solidification of the zinc drawn from the bath and which confers the coating its characteristic, metallic gray appearance.

ABRASION RESISTANCE

Galvanized coatings possess the almost unique characteristic of being metallurgically bonded to the steel base, thus resulting in excellent adhesion. Moreover, due to their being constituted by several layers of zinc-iron alloys that are even harder than steel, and an outer layer of softer zinc, they form a system that is very resistant to impact and abrasion.

ADVANTAGES IN MACHINE

In the machine the wire galvanized in warm is characterized by his cleanliness because it is a metallurgical union and residues do not become detached for friction in the compresses of the machines.
Prevents costly maintenance

ADVANTAGES IN THE FINAL PACKAGING

The hot-dip galvanizing to which our wires are subject ensures excellent results against corrosion before and after the forming of the staple, thus protecting the image of the packaged product and avoiding the appearance of dangerous and unsightly rust, even in very severe conditions; cold rooms, saline environments, etc.

COMPARATIVE ASSESSMENT OF RESISTANCE IN ACCELERATED CORROSION TESTS

IN SALT SPRAY CHAMBER

  • Hours in salt spray chamber

    Start: the two wires begin their assessment in the salt spray chamber.
    Wire after 2 hours in salt chamber, comparable to 100 days in adverse conditions. The copper wire displays the effects of corrosion. The galvanized wire displays no symptoms of corrosion.
    Wire after 6 hours in salt chamber, comparable to 300 days in adverse conditions. The copper wire displays serious effects of corrosion. The galvanized wire displays no symptoms of corrosion.
    Wire after 28 hours in salt chamber, comparable to 5 years in adverse conditions.
