The process by which zinc is coated over corrosive metals is known as galvanizing. The galvanizing process is actually a method of coating corrosive metals, such as steel and iron, with a non-corrosive metal. On product produced by Foxfab, zinc is melted and applied via what’s known as a hot dip, to the metal, providing a coating of corrosion protection from one mil to just over four mils thick.

The Benefits of Galvanizing

1. Low first cost, lowest long term cost. Galvanizing is lower in first cost than many other commonly specified protective coatings for steel.
2. Long life. The life expectancy of galvanized coatings on typical structural members is far in excess of 50 years in most rural environments, and 20 to 25 years plus, even in severe urban and coastal exposure.
3. Toughest coating. A galvanized coating has a unique metallurgical structure which gives outstanding resistance to mechanical damage in transport, erection and service.
4. Automatic protection for damaged areas. Galvanized coatings corrode preferentially to steel, providing cathodic or sacrificial protection to small areas of steel exposed through damage. Unlike organic coatings, small damaged areas need no touch up.
