Every serious area that uses steel products (construction, production etc.) is interested in a rust prevention of metal structures. Hot-dip galvanizing is recognized as one of the best ways of corrosion protection of metal structures.
Today the surface treatment technology of metal structures and elements is the main activity area of “EZI” production company. In order to increase the lifetime of different metal structures the special anti-corrosion coating is applied. The procedure of application of such coatings allows to save great resources in metal use during a long lifetime.

First step in preparing the surface before hot dip galvanizing is alkaline degreasing. This procedure is carried out in order to remove oil and other contaminants of organic origin.
Most effective methods of degreasing before hot-dip galvanizing products are:
Reagent should be Chosen based on the nature of the contamination. Among alkaline cleaners there are several varieties. But for products on which hot-dip galvanizing is used, it is recommended to use a highly alkaline cleaner. The recommended temperature for the cleaning procedure is from 60° to 80°C.
Washing is an important step in preparing a steel product for zinc coating. It follows the degreasing process. This procedure is necessary in order to remove the remaining fat, reagents. Foam residues can be on the product or in degreasing baths, if there were foaming agents in the reagents.
Different capacities are used For this step. Their choice depends on the size of the metal structure. Carrying out washing should be very careful. Residues of chemical reagents used during degreasing should be completely removed from the surface of the coating during washing. This is also important to ensure that the next stage of etching is also carried out carefully.
According to the requirements of GOST, the metal structure on which the zinc layer is applied should not have oxidizing areas and residues of the previously used coating. To meet these requirements, the surface is etched.
During this procedure, scale and rust are removed from the surface. To do this, the profile is dipped in a solution of hydrochloric acid. It helps to dissolve iron chlorides and provide the product with a smooth, smooth and shiny surface. The concentration of acid in this case should be 120-210 g/l. the air Temperature in the room should be 20°-25°C. To acid after dissolving rust does not destroy the product itself, additional substances are added to the solution.
Re-rinsing is no less important than the first. This step is mandatory. It is produced after the etching stage. As after degreasing, the metal product must be thoroughly washed. After all, during etching it formed the remains of used chemicals: salt and hydrochloric acid solution.
Additional flushing allows to prepare the profile for the next stage – fluxing, so it should be done very carefully. This procedure is performed using special washing baths. They are filled with water, after which the products are immersed in them. To save water, it is very convenient to consistently have several washing baths.
After the washing step, iron oxides are formed on the surface of the product again. They are removed during the fluxing procedure. This process is necessary for the final cleaning of the profile and obtaining a passive film. This film prevents subsequent oxidation of the surface and provides excellent wetting of the product with molten zinc.
Layer of flux in the solution is applied To the metal structure to be processed. It consists of zinc and ammonium chlorides. To prepare the solution, these elements are mixed with water. The composition of the solution should be constantly monitored, and the bath cleaned regularly. The temperature at which the procedure is performed must reach 60°C.
Placing a metal structure in a special container with molten zinc is called hot dip galvanizing. This procedure can be performed using different equipment. The ideal result in the form of a reliable coating depends on several factors:
At the stage of galvanizing the structure is immersed in a bath for 3-10 minutes. In this case, a layer of slag is formed on the product, which must be removed before lifting.
Last step is drying the finished product and checking the quality of the work done. These processes are carried out after the profile has been removed from the hot dip galvanizing bath. Cooling can occur naturally or is forced.
Drying of galvanized products can be done in cooling baths. Above each of these baths is a powerful ventilation system that allows to neutralize the vapors of hydrochloric acid.
Metal structure can be cooled outdoors. After drying, the profile is transferred to the place of storage, connecting to the site of the OTC. The finished products are checked for compliance with the requirements of the international standard.
