Steel is a robust, adaptable, cheap material which is easy to process and has good machinability. It can be used in different parts of industry. One of its big disadvantages is low corrosion resistance. Corrosion protection of steel is of a grave importance for the low cost of steel constructions. Hot - dip galvanizing is a method of anticorrosion protection. It has many advantages and the crucial is prolonged life - span of steel, without the need of maintenance. It is also the most cost - effective way for a long - term protection of steel. In the world, every 90 seconds one ton of steel transforms into rust. Out of every two tons of produced steel, one is produced to replace rust. This is the reason why the technology of hot - dip galvanizing helps saving energy in the production of steel. This paper talks about the technology of hot - dip galvanizing, about the work schedule and the responsibility of plant employees. The paper also talks about the procedures of hot – dip galvanizing, finishing of the processing and the surface protection. It also discusses the ecology issue of the process. In the introduction we learn about corrosion in general, the types of corrosion and we talk about zinc as a chemical element. After that we talk about employee tasks in the plant describing all the responsibilities of the plant workers. The technology of hot - dip galvanizing starts with logistics and the description of the plant that was taken as an example in this paper. After that, the whole hot – dip galvanizing procedure is described in detail. The paper ends with the control of the finishing process.
