The value of the zinc coating process in combating corrosion of the steel surface has grown to be a product feature demanded in ever-increasing quantities. The steel's corrosion resistance makes it ideal for applications such as air conditioning units, air ducts, metal ties, studs, siding, decking, roofing and culvert. 

Galvanizing is a zinc based coating that is applied to steel strip to resist rust and oxidation. It is characterized by a spangled finish and is used to make products such as household heating and ventilating ductwork or guard rails along the sides of a road. The steel strip is coated by either a hot dip process or an electrolytic process. A hot dip galvanizing line uses a zinc pot which acts as a hot zinc holding tank. The steel strip passes through the

pot and the zinc adheres to it. As the strip cools, the galvanized coating hardens. An electrolytic galvanizing line has a long rectangular tank which utilizes an electrical charge to help the zinc adhere to the steel strip. Most galvanizing lines are continuous and may have a temper mill or tension leveling built in after the galvanizing section.
