I-beams are a type of high-quality rolled metal products made from high-quality profile steel. As a rule, in the manufacture of products, structural steel is used without alloying additives or with their low content.

I-beams have different weight and dimensional characteristics. For the classification of profiles using the appropriate numbering and marking. This facilitates the process of selecting materials, taking into account the peculiarities of the object under construction and the expected loads on the structure.

It is difficult to underestimate the benefits of using I-profiles. These products, used in various fields, are resistant to high loads and resistant to external influences. They are durable, reliable, affordable. Pleases and pricing products. The cost of structures, compared with analogues, is modest, which is undoubtedly a plus.

In frame house building, wooden I-beams, whose dimensions are also diverse, are widely used. The use of profiles from this material allows you to reduce costs when laying the foundation, speed up the period of construction of the structure, as well as significantly reduce the total weight of the building. The use of I-beams from tree species in the future eliminates the problems associated with shrinkage, shifts, shrinkage of the structure. Hand-made wooden I-beam allows you to avoid the squeak of the finished structure, shakiness and vibrations inherent in ordinary frame buildings.

Important! Carbon steel beams are designed for indoor use, where the effects of adverse weather conditions are excluded. For outdoor work or with increased requirements for structural strength, use low-alloy steel beams.

I-profiles are produced according to the approved regulatory documents. GOST 26020-83 defines the moments associated with the manufacture of profiles with parallel edges. Aspects of manufacturing specialized profiles are regulated by GOST 19425-74. Features of the implementation of profiles with tilted edges are indicated in GOST 8239-89.

Making your own I-beams made of metal is almost impossible. The production process is carried out on specialized equipment by hot rolling. The blank for the product is blooms, which are processed at a temperature of about 1200?. The specific shape of the profile increases the strength and rigidity of the product, and also allows it to withstand increased load and evenly distribute it over the entire surface of the structure.

There is another method for the production of I-beams – welding, when the three elements of the profile are connected by welding. This process is fully automated. Welded I-beams have a smaller cross section compared to monolithic beams. Here you can also combine various steel grades, reinforcing only the “necessary” areas, which, in turn, reduces the total cost of the profile.

Profile classification and possible I-beam size 20

Beams number 20 may vary the location of the edges of the shelf. There are profiles with a bias and parallel. Faces with a slope are normal (with an angle of 6-12%), i.e. without additional marking, and with a special location. The second option differs in the type of marking: M and C. The marking “M” implies the use of the product when constructing hinged systems of a complex type. The profile, indicated by the letter “C”, is used in the construction of structures of complex geometry or in the formation of specific structures.

The cost of an I-beam profile is formed on the basis of the price of the metal and the amount of consumable material required for the manufacture of the beam. The cost is calculated for each meter of the profile.
