Galvanized steel is coated with zinc to create a physical and chemical barrier that prevents corrosion. Galvanized steel has a longer lifespan and reduced maintenance costs over its life.

There are two types of Galvanized steel available, Hot-dipped and Electro-galvanized. The major difference between these two types is the production method.

Hot-dipped galvanized steel is dipped into a vat of molten zinc, which coats the steel. The galvanized steel is removed and allowed to cool. Structural shapes such as angles and channels are frequently hot-dipped. Hot-dip galvanization yields a strong, thick coating but generally has a dull gray finish. Hot-dip galvanization is known to have a very long life averaging between 20 to 50 years.

As its name indicates, Electro-galvanized steel is a plating process where the steel is placed in an electrically charged solution of zinc and saline. This causes the zinc to chemically bond to the conductive steel. Electro-plating is frequently used for coiled sheet steel, which is later formed into shapes such as c-purloins, and corrugated sheets or can be formed and welded into pipes and tubes. Often a UV-resistant polymer is applied after electro-plating to further protect the steel and provide a paintable surface that does not need to be primed. Generally, the layer formed by electro galvanization is extremely thin; hence the life expectancy of the layer is less than that of hot dipped material.

Manufacturers galvanize products in different ways to accommodate their intended purpose. Building materials designed for structural support are commonly hot-dipped to ensure durability and longevity. Products that are easily replaceable, like outdoor furniture and gardening tools, are more likely to be electro galvanized.

There are key factors to consider when choosing between electro-galvanized and hot dip galvanized products. For example, you can evaluate the physical location that the product will inhabit. Prolonged exposure to direct sunlight, moisture, and fallen debris from overhead trees will promote the effects of corrosion. Determine the item&#;s purpose. An ornamental item would not require the same level of protection as a structural item.

Suggested Topic: Know the Differences Between Electro Galvanised Steel and Galvanised Steel

Galvanization is the process where you apply a protective coating of zinc on the iron or steel to prevent it from rusting. While doing this method, one should take proper care of the same. This process can be hazardous to the person if not done correctly. It will also cause damage or malfunction of the equipment, instrument, and many more.

Before choosing the process, one must indulge in thorough research and understand the difference between electro-galvanized steel and galvanized steel. Knowing the difference can help a person to be safe while selecting the right and most appropriate method and product according to the specific requirement and needs of the business. Otherwise, it can just be a waste of money and time.

Difference between electro-galvanized steel and galvanized steel

Here are some basic differences between galvanized steel and electro-galvanizing.

• In the case of galvanized steel, one needs to follow up a rigid cleaning process. This process is also known as the 7-bath process. But when it comes to electro-galvanizing, one need not have to follow such stringent cleaning methods.
• To achieve the galvanized steel coating, the steel is said to get dipped in the molten zinc bath at a temperature variation of 460° c. But for the electro galvanization, the steel gets prepared in a cathode in the electrolytic cell that forms a coating while using the electroplating process.
• Electro-galvanizing indeed has a very low life ranging from several months to a few years. But in the case of galvanized steel, the average lifespan is between 20 years to 50 years. However, electro galvanization produces an excellent finish. But the galvanized steel offers an unpleasant and dull finish.
• Above all, the coating thickness of the galvanized steel is about 80 to 100um. Also, the thickness depends entirely upon the dipping duration. The composition and the roughness of the steel affect the same. When it comes to electro galvanization, the coaching thickness is about 10 to 12 um. The current density and the temperature of the electrolyte determine the thickness of the coating in this case.
• The galvanized steel offers a non-uniform coating. But in the case of electro-galvanized steel, one can expect a uniform coating.

 Cost

When it comes to the cost, galvanized steel, having a normal coat thickness, becomes 40% more expensive than electro-galvanized steel. The electro-galvanized steel has a normal coat thickness, which makes it a lot affordable. The cost happens to increase proportionately with the higher coating thickness.

It becomes extremely necessary for a person to choose a reputed company to select either electro-galvanized steel or galvanized steel to get top-class service.
