The Benefits of Hot Dipped Galvanizing

What is Galvanizing?

Hot-dip galvanizing is the process of dipping fabricated steel into a kettle or vat containing molten zinc. The process is inherently simple which provides a distinct advantage over other corrosion protection methods. While the steel is in the kettle, the iron in the steel metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to steel.

The coating that develops during the galvanizing process is metallurgically bonded to the steel and virtually becoming a part of the steel itself. During the reaction in the kettle, the zinc interacts with the iron in the steel to form a series of zinc-iron alloy layers.

Advantages

• Galvanised coatings on steel can last in excess of 50 years, continually protecting steel against corrosive elements.
• Galvanised coatings provide a sacrificial protection to the steel.
• Corrosion free
• Don’t need to worry about stone chips
• Never have to re paint the trailer
• Zinc has a self-healing mechanism in it. The zinc coating sacrifices itself slowly by galvanic action to protect the base steel.

Environmental Advantages

• Zinc exists naturally in the air, water, and soil in abundance. Furthermore, zinc is essential to all life from the smallest microorganisms to humans. Zinc and steel are both 100% recyclable without the loss of properties making galvanized steel an infinitely renewable material.
• Hot-dip galvanizing (HDG) is a proven steel corrosion protection system that transcends time with minimal economic or environmental impact.
• Utilizing hot-dip galvanized steel ensures less natural resources are consumed, fewer emissions are output, and less money is spent over the life of a project.
