A fundamental characteristic that they must have is their resistance. The shelter type cabins are made to measure, according to the needs indicated by our customers. It is important that they adapt to the climatic conditions of the area where they will be located. But they must also be able to withstand transportation and be able to house the equipment that needs to be installed in them.

In stainless or galvanized steel, higher resistance

Other variables that must be taken into account are that they have the capacity to dissipate the heat of the equipment, that they comply with the technical requirements and that they have safety and control systems, in addition to allowing energy supply.

As we can see, there are many conditions and variables to take into account for their design and manufacture. Adapting to the required standards and customer needs is very important. Shelter cabins range in size from 2000x1500x2500 (WxDxH) mm to 14000x2800x2700 (WxDxH) mm.

In terms of materials, we focus on strength. That is why we use galvanized steel or stainless steel. The cabins are insulated with rock wool and internally lined with stainless steel, galvanized steel and then painted or plasticized chipboard. Galvanized steel is characterized by a zinc coating that makes it more resistant to rust, since it protects it from the action of water and humidity.

In addition, zinc is a metal that is highly resistant to scratches and provides a satin appearance that makes steel more aesthetically pleasing. Depending on different factors, a piece of industrial galvanized steel with a zinc layer thickness of only one millimeter can last up to 70 years without maintenance. In addition, it is an inexpensive material that can be recycled several times.

Rock wool is a material made of volcanic rock. It is one of the most widely used as thermal insulation and fire protection in buildings. It is a material that was discovered at the beginning of the 20th century and, shortly thereafter, it was manufactured artificially.

Individually designed cabins

In order to meet the demands of our customers, the cabins are individually designed according to the characteristics and plans they request. Subsequently, they are manufactured by studying their use, their final location and the required durability. The cabinets can withstand extreme environments in terms of temperature, humidity, tightness, cooling or vandalism, since the instruments they contain are generally of great value.

Numerous companies such as Repsol, BP, Cepsa, Exxon Mobile, Lukoil, Tecnicas Reunidas, PEMEX, have valued satisfactorily the quality and finish of our cabins for more than 30 years, making us a benchmark in the sector.

Shelter cabins allow for easy and effective installation and handling of electrical power systems, which will be protected in a pressurized and thermally controlled enclosure rather than exposed to the elements.

There are different types of heat treatments depending on the objective to be achieved and the reactions that are achieved are obviously also different. This type of treatment hardens or softens a product, modifies its structure or changes some of its characteristics so that the final result meets our needs.

The different heat treatments include carburizing, nitriding, tempering, carbonitriding, annealing, normalizing, isothermal annealing and quenching.

Tempering, the main treatment in the industry

Tempering is one of the most widely used heat treatments in the machining field. Basically, it consists of heating a material, usually steel, above its transformation point. We are talking about temperatures that may well exceed 800 or 900 degrees Celsius, and cool it quickly in water or oil. The purpose of this whole process is to obtain a much more resistant piece, in which its degree of fragility is reduced.

The tempering process seeks to achieve a balance between hardness and strength in the product.

Although it may seem strange, the use of tempered steel has been used for centuries. Already in feudal Japan, blacksmiths were in charge of making katanas, swords and other weapons with this material. To do this they smeared clay on specific parts of a steel blade and heated it in a forge, then cooled the blade in water.

Obviously today’s work processes have evolved, but at the core, the objective and principles remain the same.

Of course, steel is not the only metal that can be tempered, but it is one of the metals that offers the most possibilities, since by doing so, very attractive qualities can be achieved. For example, it is made to have a higher degree of hardness, to be less fragile, to withstand greater forces, to relieve stresses, etc.

How and why steel is hardened

To harden it, the steel must be heated to a temperature that exceeds its transformation point, which is called the quenching temperature. In this way it is possible to vary its structure, obtaining a crystalline structure that is ideal for rapid cooling of the piece. The cooling must be carried out in a certain way that will vary according to the composition of the steel in order to obtain the desired equilibrium.

To obtain different types of hardening , other elements such as carbon, nitrogen, cyanides or other compounds can be added.

The process of heating steel is called austenitization. What is achieved by heating it is to accommodate much more carbon in its structure, forming austenite, which is nothing more than a certain arrangement of iron and carbon atoms. Upon rapid cooling, martensite is formed, i.e., a crystal that gives the steel its maximum possible strength.

A complete part, including its core, can be hardened. Or only its external surface can be hardened, giving the core a different degree of hardness and flexibility.

In short, steel tempering provides this material with the properties we need to be able to manufacture parts that are resistant and suitable for the work for which they are intended, such as swas frames.

What is GRP and what is it used for?

GRP(Glass Reinforced Plastic) is a composite material, consisting of a plastic or resin matrix reinforced with glass fibers. It is a light, rigid and resistant material that offers a good response to corrosion and wear. It is also useful as an insulator, either acoustic or electrical. The truth is that its properties vary depending on the amount of fiber it contains.

Among other uses, it is used in the automotive and aeronautical industries, as well as in structural elements of construction and in water tanks.

The use of steel

Steel is an alloy of iron and carbon. The latter preserves the metallic characteristics of iron but improves its physical and chemical properties. To be considered steel, the alloy of iron and carbon must be less than 1.7%. It is a hard yet elastic material that is malleable to create different types of products.

Steel as a material has very good mechanical properties as it is very strong and also inexpensive. On the other hand, it is also possible to alloy steel with other materials such as chromium, magnesium, tungsten, zinc, etc. to improve its properties.

Stainless steel is an excellent material for its resistance to corrosion and oxidation, mainly due to the presence of chromium, which allows the formation of a thin film that is impermeable and resistant to corrosives. In addition, stainless steel is easy to clean, which makes it hygienic. It has a very low maintenance cost, resists well to both high temperatures and temperature variation and is a recyclable material, thus contributing to the care of the planet.
