What is it?

Galvanizing, also called electroplating, is a manufacturing process that applies a layer of zinc to steel or iron to provide protection and prevent rusting. There are several galvanizing processes available, but the most commonly offered and used method is called hot dip galvanizing.

Some Fun Facts About Galvanizing 

1) The hot-dip galvanizing process adds years to the life of your steelwork and is far more economical than painting or powder coating.
2) This process is a 150-year-old practice.
3) When the Brooklyn Bridge was built, more than 14,500 miles of hot-dip galvanized wire were used for the four main cables. 100 years later, when the bridge was renovated, the hot-dip galvanized cables were still in excellent condition
4) Kettles used for galvanizing are set to temperatures that vary from 435 C and 454 C
5) Corrosion is caused by metals' tendency to be exposed to air and moisture
6) Galvanized steel was named after an 18th-century Italian scientist, Luigi Galvani.
7) The zinc coating on galvanized steel is uniform: inside, outside, corners, and edges.
8) Galvanized steel is one of the oldest and most widely used materials of construction and manufacture.
9) Our air is cleaner and has fewer corrosive emissions thanks to hot-dip galvanizing.
10) Galvanized steel can be manufactured using a process known as "dry galvanizing" or "shot blasting," which makes it highly adhesive for paint, rubber, and powder coatings.
11) Galvanized steel has become the reference material in the automotive industry.

In addition, the ease of use is very attractive for steel suppliers. That's an incredible figure, especially when you consider that corrosion and rust costs the US economy billions of dollars each year.

Used in automobiles:

In fact, galvanized steel sheets are widely used in automobile production to improve corrosion resistance. So, if your car hasn't rusted out yet, chances are you owe thanks to galvanized steel.

It is used for a variety of other things as well:

Galvanized steel has numerous applications beyond construction and automotive. Zinc plated steel is used to make corrosion resistant nuts, bolts, and nails. It is used for outer tubing when plastic tubing is not strong enough. It is used for benches at bus stops, balconies, patios, stairs, corridors and stairways. The light poles on highways are made of galvanized steel, as well as pylons that support high-voltage electricity distribution to factories, schools and hospitals.
