Painting of metal structures and building structures

Metal structures, like any other type of building structures, need to be treated and protected from harmful environmental influences. In many respects, their integrity and the length of their service life depend on this. Usually there are two types of protection of metal structures: fire protection and anticorrosion protection of metal structures.

Fire protection of metal structures

Increasing the fire resistance of metal structures is usually achieved in the following ways:

  • use of mineral wool as an element of fire protection
  • protection of metal structures with drywall
  • application of fire-resistant paints

All three methods have both advantages and disadvantages. For example, in order for fire protection of metal structures to operate for a long time (from 90 minutes), the use of drywall and mineral wool will cost much less. At the same time, fireproof paint allows you to leave the structure in its original form and, therefore, do not change the architectural design. During heating, the paint begins to swell and expand, while creating a heat-insulating layer up to 3 cm, which is charred, but does not allow for a certain period of time to heat the metal structure of the building to a critical temperature. If the metal structure is not treated with fire-resistant paint, then at a temperature of 900 degrees (the critical temperature of the metal), the metal structure will lose its load-bearing capacity after 5 minutes. Naturally, the thicker the applied layer of fireproof paint, the thicker the protective layer formed under the influence of temperature.

Anticorrosive protection of metal structures

The main damage from environmental impact to metal is caused by corrosion. The simplest and most reliable way to protect against corrosion is to paint metal structures with special paints and enamels. The advantages of this method are obvious: easy application:

  • ability to get any color
  • the ability to process metal structures of large dimensions and complex configuration
  • low cost compared to other types of protective coatings

Painting of metal and building structures

Metal structures have a number of advantages over other materials: fast installation, no problems when transporting structural elements, as well as a long service life. The only drawback of metal is its corrosion under the influence of both natural forces (wind, sun, water, temperature changes) and human factors (mechanical damage). When considering this issue, it should be noted that the metal structure will be more stable when added to its zinc alloy. Also, the current range of anti-corrosion paints will help to avoid this problem. One of the main factors in choosing a paint is its characteristics: fire protection, moisture resistance,adhesive strength, resistance to direct sunlight. It is necessary to consider the fact that the color of metal structures will significantly transform the room (industrial shop, warehouses), where the workers will be located. The color of the paint affects the mood in which the person is, and, consequently,the productivity of the enterprise. Psychologists have studied that with a green (blue) color of the metal, employees perform a greater amount of work than with a black or red color of the structure.

Use of industrial mountaineering when painting metal structures and building structures

Painting metal structures often involves the performance of work by industrial climbers who perform the task at a high altitude. This type of work requires additional funds for high-quality and safe performance. All climbers who work on painting various types of objects have special training, as well as equipment that is used at height (rope, carabiners, zhumars, and in some cases — automatic towers). All equipment is thoroughly checked before use. The ability of industrial climbers to do their work on a wide range of objects: pipes, water towers, TV towers, bridges, factory workshops, cooling towers of thermal power plants, elevators, residential buildings, skyscrapers, makes them indispensable in the implementation of orders in this service sector.

Conditions that allow you to produce high-quality paint of building structures

Painting of building structures involves several operations, each of which must be performed in strict order, subject to numerous conditions. First of all, the work must be done in such a way that the metal is not exposed to both internal and external corrosion. Metal structures are the least protected from the forces of nature. Industrial climbers focus their attention on this problem when painting metal structures. Before applying enamel to the metal, it is necessary to thoroughly clean it from foreign bodies. If this condition is not met qualitatively, the enamel will not adhere well to the metal, which will later lead to the separation of the paint from the surface. If you re-paint building structures (repair, color change), it is necessary to clean the entire surface with an abrasive material. When painting new metal structures, it is necessary to carefully treat the surface with soil, then proceed directly to applying paint to the metal. The color condition of such a surface implies a complete novelty of the object, which is extremely rare. To do this, there is a paint whose properties include: rust Converter, primer, paint. When re-painting building structures, it is necessary to completely remove the layer of previously applied paint. Its surface may contain various kinds of irregularities formed after long operation. Surface cleaning is performed using a twitch, a skin (manually), or automatically, when using sandblasting devices. The material for the primer may be as minium and paint, diluted with white spirit. Adhesion — the adhesion between the paint and the surface of a metal structure. The performance of high-quality work is more dependent on the performance of priming work, since it is under the condition of applying a high-quality ground coating that the durability of painting will depend. Before the painting of building structures, the primer material should dry, after which you need to start applying paint.

The sequence of painting of the metal

Painting metal structures implies a very responsible and time-consuming work. Before the complete completion of the object, the industrial climber will have to complete several important stages: The first stage before painting building structures is to clean the surface of various types of formations. Cleaning from rust and old paint is carried out by sandblasting, as well as processing with metal brushes. After complete cleaning of the surface, it must be degreased.

Primer is the most important element of work when painting building structures. By performing this stage correctly, the durability of the structure is achieved.

Painting is the final stage and is applied in one or two layers.

Painting of building and metal structures

Advantages of using services provided by industrial climbers:

  • minimum price for painting works
  • high speed of task completion is achieved when using high-tech equipment
  • there is no need to build a working frame for painting metal structures
  • the work done by highly qualified specialists will guarantee the durability of the painted structure

The quality of the work performed will be so high that the customer will turn to this method of painting more than once.

Painting building structures using industrial mountaineering will give you the opportunity not only to save precious time, but also the costs provided for the execution of the order.
