Methods used in galvanizing steel or iron

Galvanizing is done to protection the steel of iron from corrosion. In galvanizing process the steel is coated with zinc. The galvanizing of steel is achieved by different methods. Some of these methods are discussed below

Hot dip method

In the hot dip galvanizing, the steel or iron is dipped into the molten zinc. The surface of the galvanizing material is thoroughly cleaned before dipping. This process gives thick coating of zinc on the steel. Later this coating freezes into crystal pattern known as spangle.

However, the negative side of this process is that a thick multilayered coating is formed between steel surface and inner layer of zinc coating.  These layers can peel or flake of, when the iron or steel is bent.

Electro galvanizing method -

The second process is eletrogalvanising. Here, the immersion of the steel and iron in the electrolyte gives coating of pure zinc on the steel or iron. The electrolyte is solution of zinc sulfate or cyanide. The major benefit of this type of coating is that the thickness of the coating can be controlled accurately.

The flip side of this process of galvanizing is that the thick coating cannot be taken through this method.

Sheradizing

Sheradizing method GI Sheet Dealers in Delhi involves putting cleaned steel or iron in the enclosure, where metallic zinc dust surrounds the steel and iron.  Then the material is heated to produce the zinc alloy coating. The coating in this method confirms to the configuration of the element. But this method can be used only for small objects.

Spraying method

Spraying method is very simple method in which spray of fine molten zinc is applied on the steel or iron. The coating is then heated to produce the galvanized steel or iron. The benefit of this method is that the coating produced is very fine and does not peel or come off. And also it is less brittle. But it also have its negative points, the coating sometimes becomes porous. The pores are then filled with corrosive materials.  

Painting method

The painting method involves applying zinc dust pigment on the surface of steel or iron to galvanize them. But this method is not an effective method to produce galvanized steel. The painting can easily come off and it comes with primer, which exposes the steel completely. Also with well painted steel, it is not possible to differentiate between a zinc and galvanized steel.

The galvanized GP Sheets Suppliers in Delhi steel is used widely in homes and commercial building as window and door hoods. It is also used as roof sheets. 

Advantages and Applications of GI Sheets
