WHAT IS GALVANISING?

WHAT IS GALVANIZING?
Hot-dip galvanizing is the process of coating iron, steel, or aluminum structures with a zinc layer, protecting the base metal from weather damage and providing protection against corrosion. Galvanized steel is widely used in applications where rust resistance is required. The metal is coated in zinc by first passing the metal through a molten bath of zinc at a temperature of around 860° F (460° C). Once the metal is exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO). Zinc oxide then reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3). This produces a dull grey, strong material that stops further corrosion, and protects the steel from the elements. Galvanized steel can be identified by the crystallization pattern on the surface, often referred to as a “spangle”..

WHY GALVANISE?

Due to the strength of the metallurgical bond, along with its ability to withstand very aggressive handling, galvanized coatings continue to be unmatched to date.

The metal is first cleaned, and then the zinc is adhered to the steel using heat as a catalyst. Zinc, unlike other surface coatings, will form a metallurgic bond to the steel, outperforming any other mechanically bonded coating system on the market. Once coated, the zinc will corrode preferentially to the steel using what is called “cathodic” or “galvanic protection”, so that over time, if a scratch appears on the surface, the zinc will react to the elements before the steel will be affected. Bare metal up to one-quarter inch will also be protected by the bonded zinc immediately adjacent to the bare area.

Hot dip galvanizing?

Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C).
