Galvanization Sheets

Galvanization Sheets

Description : Galvanization is a process that involves applying a protective zinc coating to steel or iron to prevent corrosion. This technique has been widely used for many years due to its effectiveness in increasing the lifespan and durability of metal structures. Galvanization is typically achieved through a hot-dip galvanizing process, where the metal is immersed in molten zinc, allowing the zinc to bond with the surface of the metal.

Uses :

The primary purpose of galvanization is to provide corrosion protection. When steel or iron is exposed to moisture and oxygen, it can undergo a chemical reaction known as oxidation, leading to rust formation. By applying a layer of zinc through galvanization, the zinc acts as a sacrificial anode, corroding instead of the underlying metal. It effectively prevents rust from forming and extends the lifespan of the coated material.

Benefits :

One prominent example of galvanized products is galvanized steel structures. These structures are widely used in construction, infrastructure development, and manufacturing industries. Galvanizing steel helps protect it from corrosion, extending its lifespan and ensuring structural integrity. Galvanized steel structures are ideal for outdoor applications and can sustain harsh weather conditions. [2,3]

Types :
1. Hotdip gelvanizing
2. Electrogelvanizing
3. Sherardizing
4. Galvannealing


Making Process :

• Pickling
• A dilute solution of hydrochloric acid removes surface rust and mill scale to provide a chemically clean metallic surface which is required for galvanization.
• Fluxing
• Through the final surface preparation step, any remaining oxides are removed in a zinc ammonium chloride solution and a protective layer is deposited on the steel to prevent any further oxides from forming prior to galvanizing.
• Galvanizing
• Following surface preparation, the steel will be immersed in a bath of molten zinc maintained at a temperature between 815º-850º F (435º-455º C). While steel is immersed in the kettle, the zinc reacts with the iron in the steel to form a series of metallurgically bonded zinc-iron alloy layers with the final top layer 100% zinc.
• Inspection
• The inspection process of galvanized steel is fairly simple. Zinc will not react with unclean steel, therefore a visual inspection of the product will provide a good assessments of the quality of the coating. Coating thickness and surface condition inspections complete the process to ensure compliance with specification. Electronic gauges are used to give quick and accurate measurement readings of the coating.

Galvanized Steel Angles

Description : Galvanized angles are structural steel angles coated with a protective layer of zinc to prevent rust and corrosion. The galvanization process involves dipping the steel into a molten zinc bath, which forms a barrier that is highly resistant to moisture and environmental wear.

Sizes :

20MM X 3MM , 25x3, 32x3, 40x5, 50x5, 80x8, 100x10 100x12, 150x8, 125x10, 150x10 150x12

Uses :
