Painting of metal structures

Painting metal structures is an important factor in the erection of any structures. The coating of metal, paint and varnish products provides some protection against external factors, such as moisture, chemicals and much more. As a result, corrosion of the metal is prevented and, accordingly, the service life of the structure increases.

Need painting of metal structures price varies depending on different factors. The painting process is performed in several stages:

• Preliminary preparation of the surface to be painted;
• Coating with a primer;
• Directly paintwork.

Preliminary preparation

Initially, it is necessary to clean and degrease the working surface. Stages of surface preparation:

• Getting rid of the previous coating, as well as dust and dirt;
• Removal of rust;
• Surface grinding;
• Degreasing of metal.

Primer

Pre-prepared surface is covered with an anti-corrosion compound. It is necessary to prevent metal corrosion and improve the adhesion to the primer. After it dries, a primer is applied.

Painting metal

The surface is painted immediately after the primer has dried. Painting can be carried out both manually and with the aid of a high-pressure apparatus.

The mechanized method of painting is the least difficult and therefore not expensive. In specialized premises, automatic and manual spray guns are used. The advantages of the method are:

• External factors, such as weather, do not affect the painting process;
• It is carried out, as a rule, by automation.

One drawback to this method is the limited capacity of the work area. And as a result, it is not possible to paint large-sized structures.

Painting at high altitude is associated with certain difficulties. Large amount of expensive work. For such a painting will have to rent a lift or install scaffolding. For these purposes, recently it is popular to hire mountaineers-builders. They descend to the workplace directly from the roof. Arriving at the construction site, they primarily fix the Alpine outfit and then immediately begin to work. At the end of this work there is a great advantage, since after the work of the builders of climbers, it is not necessary to disassemble anything.

A large number of paint coatings are used, which are selected in connection with a variety of factors - the duration of the daylight of a particular region, humidity, air temperature, the presence of chemical effects and many others. The service life of the building depends on both quality installation and its additional processing.
