Painting of steel structures: main stages and requirements

In the construction and production involved a huge number of a variety of metal structures. Their relevance is explained by a number of undeniable advantages. They are much lighter than reinforced concrete, yet durable and durable. However, metal has one "weak" place - oxidizing, it turns into rust, that is, it collapses. To prevent this process, different methods are used. The most common and effective is, of course, staining. It is quite cheap and reliable protection. Painting metal structures not only prevents 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 taken: removal of the old coating completely or only from certain areas (where blistering, peeling, etc. are observed), cleaning and processing with special means. If such procedures are not carried out, further work may lose all meaning. Inflammations assume the presence under the coating of the air layer. And this means that the metal in these places is probably corroded by corrosion.

Painting metal structures involves pre-stripping, as well as surface treatment with anti-corrosion agents. Stripping can be done both manually (sandpaper), and with the use of special mechanisms. Removed rusted metal layer. 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 mandatory. It takes even more time than directly painting metal structures. The fact is that the primer should dry well, this, of course, takes time.

Among other things, in carrying out this kind of work you need to know and some subtleties. For example, a cold metal can not be painted. This is because there is always condensation on it. Therefore, the metalwork should be painted only on the surface of normal temperature. The technology of this process involves the use of special types of primer. The right choice of paint also means a lot. The final result depends on this. Most often used special dyes, which added anti-corrosion components.

Prices for this kind of work can be quite different. Firstly, the cost, of course, depends on the firm that will perform repairs. A well-known company will request a corresponding 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 can also depend on the attendant factors. For example, sometimes this process involves working at altitude. Of course, you will need additional installation equipment, as well as specialists trained to work with it.

It is better to contact a proven firm. Then you can be sure that after a few months the paint will not start to go away, and you do not have to repeat the repair again.
