A metal beam is a special type of high-quality rolled metal and is mainly used to create large-span structures of industrial buildings, which can significantly reduce the overall load on the base of the structure. Today it is one of the most important components of any work sites, crane beams, bridges, ceilings and other types of metal structures.
Each type of this product has its own individual characteristics, which allows you to make the right choice. It must comply with the requirements for technical specifications to be able to create the necessary design. In modern construction, a metal beam is widely used. Her selection is carried out according to criteria such as wall size, shelves and appearance.
A metal beam is made in two main types. The main difference lies in the different shape of its cross section - this is a T-beam and I-beams. The T-beam, when viewed from the end, resembles the letter "T", while the I-beam is the letter "H" or the double inverted letters "T", for which, however, it got its name. The main field of application of both is as load-bearing floors of buildings and structures for various purposes.
In construction, a metal beam helps to redistribute the load on the supporting structures. They then evenly transfer it to the
foundation. The metal
beam is a kind of skeleton of the building, which is gradually filled with other structural building materials. That is why special demands are made on the quality of manufacture of this element. The classification of this type of metal is based on the technical characteristics:
in the form that she has;
by the thickness of the shelves and walls;
depending on the location of the edges of the shelves;
according to the material that was used for its production.
In addition, the metal beam varies in purpose and manufacturing method.
The beam can be called a kind of beam, which has a variety of sizes and cross-sections. It was created specifically for the possibility of distributing the load on the supporting structures evenly around the entire perimeter of the building under construction. Recently, a metal
I-beam has been widely used
, which is widely used in the construction of overpasses, bridges, hangars, warehouses, not to mention industrial and civil facilities.
An important point in the selection for construction is the correct calculation of the metal beam. Regardless of the material, type of section and type of structure, its calculation is carried out according to one algorithm. First, a design scheme is drawn up, then internal efforts are determined. The next step - according to internal efforts, the beam section is selected and at the final stage all the obtained results are checked. Verification allows you to increase or decrease the cross section to achieve the optimum degree of strength.
