What is galvanized sheet?
As one of the most widely used products in the construction, automotive and many other fields, galvanized sheet plays an important role in protecting metals against corrosion. Using the galvanization process to increase the durability and resistance of metals against environmental conditions has a long history and has long been known as an effective method
Galvanized sheet is a type of steel sheet that has a thin layer of zinc metal added to its surface in order to protect against corrosion.
This layer of zinc metal is usually applied to the steel sheet through a chemical or electrical process. The main purpose of this process is to prevent direct contact of steel with the environment and its corrosion.
Galvanized sheet is used as a protective material for steel. Because steel tends to corrode in certain environments, such as moisture, air, and oxygen. Applying a thin layer of zinc on the surface of the steel protects the steel from direct contact with these factors and increases its resistance to corrosion.
Due to its outstanding features, this type of sheet is used in various industries, including the construction industry, automotive industry, marine industry and storage tanks, as a durable and resistant material against various environmental conditions.
Galvanization is known as the method of coating metals with a layer of zinc to prevent rust and corrosion of metals. This invention has provided the basis for widespread use in the metal and construction industries. You can read the history of galvanization in other articles on the site.
Features of galvanized sheet
Galvanized sheet has unique features that make it interesting for various uses. In the following, the features of the galvanized sheet will be explained along with more details:
• High resistance to corrosion:
Galvanized sheet has high corrosion resistance. This resistance is the result of the zinc metal coating that is applied to its surface. Zinc metal acts as a protective layer and protects the underlying steel from direct contact with corrosive agents.
• Long-term durability:
Another feature of galvanized sheet is its long-term durability. These sheets are usually able to resist corrosion and rust in the long term. This feature makes the products made of galvanized sheet last even under harsh environmental conditions
• The ability to withstand harsh environmental conditions:
Galvanized sheet usually has the ability to withstand harsh environmental conditions such as humidity, salt, different temperatures and atmospheric changes. This feature makes these types of sheets can be used in a variety of environments, including coastal areas or environments with unfavorable weather conditions.
• The beauty and smoothness of the surface:
The galvanized sheet has a smooth and beautiful surface, which is suitable for use in environments where the appearance of the final product is important. This feature makes these types of sheets to be used in the construction and display of some products and buildings, including in building infrastructures or in interior and exterior decorations.
In general, galvanized sheet is used as a resistant, durable, and beautiful material in various industries due to the above features and plays an important role in protecting metals against corrosion and rust.
Galvanization methods
Galvanization is done in two main ways: hot and cold. These two methods use the immersion process and the electric process to apply the galvanized layer on the steel surface, respectively. Below we explain these two methods:
Hot galvanizing:
The steel sheet is immersed in the bath of molten zinc and due to the high temperature and the reaction of zinc with the steel, a galvanized layer is created on the surface of the steel.
Cold galvanizing:
Electric current is used to apply zinc on the surface of the steel sheet. In this method, a steel sheet is used as a cathode and a piece of zinc is used as an anode, and the electric current creates a galvanized layer on the surface of the steel.
These are the two main methods of galvanization, which are chosen depending on the needs and conditions used
Conclusion
Due to the long history and wide applications of galvanized sheet, this product is considered as one of the most important materials in various industries. Due to its outstanding features, galvanized sheet is considered not only as a protection against harsh environmental conditions, but also as an ideal choice for beauty and durability in construction and other industries. Galvanizing steel sheets is a proven method to increase the useful life and efficiency of metals in dealing with corrosive agents and is still used as an effective solution in the industry.
