What is LSTK profile and what is it for?

LSTK profile is distinguished by high strength characteristics. Strong and durable structures made of such parts are widespread in Western Europe. The profile is subdivided into several varieties and can have various shapes. In this article, we will find out what the LSTK element is and understand the areas where it is needed.

LSTK is a special construction technology, according to which prefabricated buildings are erected. They have a metal frame consisting of thin-walled profiles of various modifications. The abbreviation LSTK means light steel and thin-walled structures. We are talking about hangars, warehouses, industrial and agricultural buildings. Also, the LSTK profile is often used in the construction of residential buildings, garages, service stations, parking areas - the list of possible buildings is huge.

Currently, the LSTK profile is actively manufactured throughout Russia. Initially, only warehouses and huge industrial hangars were built from this material, but over time, the popularity of such structures began to grow at a frantic pace. Today the LST profile is used very actively and turns out to be relevant in the construction of a variety of buildings. Structures are obtained from LSTC profiles that demonstrate excellent seismic resistance.

Let's get acquainted with the main operational characteristics of LSTC profiles.

• The material in question has a relatively low mass. The weight of light steel parts is 10 times less than the weight of bricks and concrete. Due to this characteristic, buildings can be built on a lightweight foundation, which significantly reduces construction costs.
• LSTK is a material that retains and retains heat very well. According to experts, the profile, the thickness of which reaches 10 cm, is similar in terms of heat preservation to brickwork with a thickness parameter of 80 cm.
• Since the LSTK profile is such a heat-insulating material, the owners of buildings erected using the considered pre-fabricated technology have every chance to save up to 60% of energy for heating.
• LSTK profiles are characterized by environmental safety. They make not only high-strength, but also environmentally friendly buildings. Steel cannot act as a source of hazardous substances, therefore it cannot have a negative impact on the environment and the human body.
• Structures made of LSTK components are designed in such a way that the dew point in them is located outside the framework of the structure itself. Thanks to this approach, even against the background of severe frosts, the structure does not freeze.

Buildings erected from the LSTK profile are built in accordance with all the necessary GOSTs. Installation work is inexpensive and does not take much time. The result is very strong and durable structures that can easily last up to 120 years. With the right and thrifty attitude, this period can be even longer.

LSTK profile is made on special equipment. Products of different types and shapes have different sizes - length, thickness and width. For example, the standard sizes of parts can be 150x50 or 150x45.

As mentioned above, LSTC profiles are divided into different types. Each of them demonstrates its own design features, dimensional parameters, shape and device. Different metal parts are used for different jobs. Let's take a closer look at the frequently used LSTK profiles and learn about their parameters.

Guiding profile type. The production of such a part is carried out from molded steel strip by means of cold rolling. The U-shaped structure is attached to the structure using a special roll forming machine. The production of the varieties in question is made from durable and wear-resistant galvanized steel, which has full protection against corrosion.

From such elements, very strong and durable structures of high quality are obtained. The finished profile of the type in question is made long enough, has a smooth surface. Often such details are used to prepare the frame for the construction. It is to such a structure that the rack profiles are subsequently attached.

This is a LSTK rack-type profile. It is a long piece made of a solid steel strip. The bending of this product is ensured by special roll forming equipment in cold rolling conditions. Like the U-shaped element, the C-shaped products are not complemented by perforations in their device. To strengthen the existing bearing properties, a stiffener is provided along the entire structure.

A similar profile is installed simultaneously with the above-described U-shaped structural element. These parts are required to be attached to each other. The dimensions of such profiles must be selected very carefully so that their joining is as tight and strong as possible. It is necessary to take into account the fact that the greatest load of the entire structure will be transferred precisely to the rack-type profiles, therefore, when choosing them, it is especially important to make sure of their rigidity and strength.

This detail is also called a hat detail. It is a continuous component of great length. It is made from rolled galvanized steel. It has a curved shape, made in the form of the Latin letter omega. The part acquires this structure due to cold rolling on roll forming equipment. In the construction field, the considered type of profile is used for the installation of facade and roofing battens. The parts are very lightweight, and provided that they are correctly sized, their installation is very simple and hassle-free.

A similar assortment of metal has both a shape and a material of manufacture, as is the case with an ordinary rack-mount profile. It is also made of galvanized steel coil. It is run in the form of strips by cold rolling through a roll forming machine. The design of the profile under consideration also has a stiffener.

This profile differs from the usual one in that an offset perforation is applied along its entire length. Special openings facilitate unobstructed air penetration. Thanks to this, the appearance of cold and frozen zones in the metal frame base of the building is noticeably reduced. The use of the details under consideration contributes to a better and more efficient thermal insulation of wall structures and ceilings, due to which the finished house does not need auxiliary insulation.

Rack parts can be used as vertical racks along the construction of load-bearing walls, internal partitions. These elements are used in the construction of roofing and interfloor ceilings, equipment of the attic.Rack structures must be extremely durable.

Long piece made of galvanized steel. Differs in wear resistance and durability. The production method of such products is cold-rolled. A distinctive characteristic of the profile in question is the presence of perforation. It is applied along the entire length of the part. The holes are made even, but with a slight offset. This ensures unhindered air circulation.

The construction of certain buildings using LSTK profiles provides for the use of a number of necessary component parts. These include the following elements:

• self-tapping screws required for assembling panels;
• steel tape needed to form cross-type ties;
• fasteners for steel tape (self-tapping screws are meant in the required quantity).

Different manufacturers and firms offer different sets of LSTC profiles for consumers to choose from. They include different components, which is reflected in the final cost of goods.

It is not for nothing that LSTK profiles have become very popular and in demand. Very durable, wear-resistant and reliable buildings of various types and modifications are obtained from such parts. Using the elements in question, it is possible to install the following structures:

• alcove;
• barn;
• utility block;
• greenhouse and many other buildings.

LSTK profiles are also attractive because they can be used to build not only capital construction of any modification, but also other components, for example, reliable floors.
