How to Produce Galvanized Sheet

Galvanized sheet is a product obtained by coating metallic zinc on flat steel material. It is preferred in many areas due to its corrosion resistance. It is especially important for materials to be used outdoors. The coated material provides years of rust-free use. After the coating process, the quality of the zinc coating is increased by chromating or oiling.
Galvanized sheet has C surface quality, which is called the best quality. In this way, it is used in surface applications. It has a bright appearance. It is easy to shape when subjected to depth or bending processes. Another advantage of the coating is that it can be painted. If there is oil or similar processes on the surface, it is necessary to clean it before painting. In this way, it will be in perfect harmony with the paint.

Materials to be used in the automotive industry are subjected to salt testing. The materials that pass the test are ready to be used in production. Galvanized materials can pass this test without any problems and can be installed in various parts of the vehicle. Galvanized sheet is also used in the building sector. It gives successful results in applications such as roof, door, profile. In the white goods sector, galvanized materials are preferred for the interior parts of the devices. Recently, it has been used on exterior surfaces.

Galvanized Sheet Production by Hot Dip Method

The hot dip method is the most widely used galvanized sheet production method in the industry. Zinc is a metal that melts at a temperature of 419.5oC. Volatility is gained by going to higher temperatures such as 450-460oC. In this way, it is provided to be coated with the hot-dip method of solid iron. The success of the method is due to the strong adhesion of iron and zinc. In our country, this process is done by automatic and semi-automatic machines. As changes are made in processes such as bath temperature, dipping time, cooling, there will be differences in the appearance of the coating.

Galvanized Sheet Metal Production by Electro Dipping Method

Another method used in galvanized sheet production is electro galvanized coating method. Anode and cathode electrodes are immersed in an electrolyte-filled boiler. Zinc is attached to the anode and iron material to the cathode. Electrons from the anode stick to the surface of the cathode. At the last stage, passivation is done and the coating process is completed.
