Treatment of steel products with heated zinc has been and remains the most popular procedure to prevent corrosion of the metal. The prevalence of the method in construction and industry is provided with a high degree of protection against rust while maintaining heat and energy conductivity. For large enterprises that work with large volumes of production, the method is also cost-effective. Metal structures protected by this technology can be used in urban construction (power line supports, bridge structures, railings). It is acceptable to use the method to strengthen household utensils – dishes, tanks or pipes.
Hot dip galvanizing in Nizhny Novgorod is carried out in several stages. The first step is to perform the preparatory procedures. These include thorough cleaning of oils, grease, rust and washing. Be sure to dry to prevent poor-quality processing result. Particular attention should be paid to the parts of the structure in which there is a thread or bolts. They become an additional source of corrosion. After performing the necessary procedures, the workpiece is dipped into a liquid mass heated to 450 degrees. With proper preparation, the solution should fill the pores in the structure of the steel part as much as possible. The technology assumes that after the end of processing zinc will continue to penetrate into the metal. On average, the rate of penetration of the alloy into the material is 2 mm. per year.
To ensure a really strong and durable coating should take into account the requirements of GOST 9.307. Special attention is paid to checking the fixation strength of the protective layer and material. This can be done in different ways:
