A huge number of the most diverse metal structures are involved in construction and production. Their demand is explained by a number of undeniable advantages. They are much lighter than reinforced concrete, while durable and durable. However, the metal has one "weak" place - oxidizing, it goes into rust, that is, it collapses. To prevent this process, different methods are used. The most common and effective is, of course, staining. This is a fairly cheap and reliable protection. Painting of metal structures not only protects them from corrosion, but also gives them an aesthetic appearance.
This process sometimes involves simply priming and applying paint. But this type of processing is rarely used, mainly to protect new objects. Most often, the technology of painting metal structures involves preliminary preparatory work. The following measures can be carried out: removal of the old coating completely or only from certain areas (where bloating, exfoliation, etc. are observed), cleaning and processing with special tools. If such procedures are not carried out, further work may lose all meaning. Swellings suggest the presence of an air layer under the coating. And this means that the metal in these places is probably corrupted by corrosion.
Painting of metal structures involves preliminary cleaning, as well as surface treatment with anti-corrosion agents. Stripping can be done either manually (with emery paper), or using special mechanisms. The rust-affected metal layer is removed. And with the help of special chemicals, the corrosion process is suspended.
The primer is made in order to level the surface and increase the adhesion (adhesion) of the paint to the metal surface. Therefore, this step is a must. It takes even more time than directly painting metal structures. The fact is that the primer must dry well, this, of course, takes time.
Among other things, when conducting this kind of work, you need to know some subtleties. For example, cold metal cannot be painted. This is because condensation is always present on it. Therefore, painting of metal structures should be carried out only on the surface of normal temperature. Moreover, the technology of this process involves the use of special types of primers. Choosing the right paint also means a lot. The final result depends on it. Most often, special dyes are used, in which anti-corrosion components are added.
Prices for this kind of work can vary quite a lot. Firstly, the cost, of course, depends on the company that will make the repairs. A well-known company and will request the appropriate amount for its services. But you can be sure that the coloring, especially the preparatory stage, will be carried out qualitatively. The cost of painting metal structures may also depend on related factors. For example, sometimes this process involves working at height. Of course, you will need additional installation equipment, as well as specialists trained to work with it.
It is better to contact a trusted company. Then you can be sure that after a few months the paint will not start to come off, and you do not have to repeat the repair again.
