I-beam: size table, weight and technical characteristics of profiles

I-beam: size table, weight and technical characteristics - these are the data that will definitely come in handy in the construction of civil and industrial facilities. I-beams are quite diverse in their design. This article provides information about the advantages of profiles from different materials, their sizes and modifications.

Specific form I-beam increases the strength and rigidity of the product, and also allows it to withstand increased loads

Design features of the I-section

An I-beam is a standard beam with a cross-section that resembles the letter "H". Modern construction of bridge structures, ceilings, multi-storey buildings or hydraulic structures is impossible without using this type of profile. It is also widely used in mechanical engineering.

Since I-beams are a building material that is used in critical structures, their manufacture is carried out strictly in accordance with state standards.

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

I-beams have different weights and dimensions. For the classification of profiles, the corresponding numbering and marking is used. This facilitates the selection of materials, taking into account the characteristics of the object under construction and the expected loads on the structure.

It is difficult to underestimate the benefits of using I-beams. These products, used in various fields, are characterized by resistance to high loads, immunity to external influences. They are durable, reliable, affordable.Pleases also the price policy of products. The cost of structures, in comparison with analogues, is modest, which is undoubtedly a plus.

When buying I-beams, you should definitely pay attention to their number, by which you can find out the height of the profile

In frame housing construction, wooden I-beams are widely used, the sizes of which are also varied. The use of profiles from this material allows you to reduce costs when laying the foundation, to speed up the construction time, and also to significantly reduce the total weight of the building. The use of I-beams from wood species eliminates further problems associated with shrinkage, shifts, and shrinkage of the structure. A self-made wooden I-beam avoids the squeak of the finished structure, the instability and vibration inherent in ordinary frame buildings.

Important! Carbon steel beams are designed for indoor use, where exposure to adverse weather conditions is excluded. For outdoor work or with increased requirements for structural strength, low-alloy steel beams should be used.

Features of the manufacture of I-profiles

I-beams are produced in accordance with the approved regulatory documents. GOST 26020-83 defines the moments associated with the manufacture of profiles with parallel edges. Aspects of the manufacture of specialized profiles are regulated by GOST 19425-74. Features of the execution of profiles with inclined edges are indicated in GOST 8239-89.

The production of an I-beam is carried out by welding three main elements, resulting in belt seams

Making an I-beam from metal with your own hands is almost impossible. The production process is carried out on specialized equipment using the hot rolling method. Blooms, which are processed at a temperature of about 1200 ℃, serve as a blank for the product. The specific shape of the profile increases the strength and rigidity of the product, and also allows it to withstand increased loads and evenly distribute it over the entire surface of the structure.

There is another method for the production of I-profiles - welding, when 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. It is also possible to combine different grades of steel here, strengthening only the "necessary" sections, which, in turn, reduces the overall cost of the profile.

I-beam 10: dimensions, characteristics, scope

I-profile No. 10 is the smallest representative of these structures. Despite its light weight, the product is quite tough. Such a profile is distinguished by increased resistance to loads, high reliability and stability of geometric characteristics for the period of operation.

A meter of I-profile in this modification weighs 10 9, 46 kg. The tenth I-beam can be made in lengths from 4 m to 12 m.

By the position of the faces, inclined and parallel I-beams are distinguished. They are marked accordingly, where "Y" is a profile with a slope of the edges and "P" is a beam in which the edges are parallel.

I-beam 12: dimensions and profile weight, marking

This type of profile is made in accordance with the provisions of GOST 8239-89. It is presented in several variations. The marking defines the features of the product.So, the letter "B" denotes the edges of the shelves without inclination on standard I-beams. The "Ш" marking indicates the parallelism of the edges of the shelves on wide-flange profiles. The letter "K" characterizes the columnar I-beams. Narrow-shelf profiles are marked with “Y” mark, and middle-shelf beams are marked with “D” index.

I-beams No. 16 are of several types. It is technically possible to produce beams where the flange edges are parallel, profiles with an inner edge slope from 6% to 12% and an inclination from 12% to 16%. Welded profiles are also produced where the upper and lower flanges are attached to the base. As a variation of such a profile, there is a non-standard I-beam, where the width of the upper and lower flanges is different.

Formulas for determining the required weight of an I-beam

The calculation of the mass of the I-profile should begin with determining the weight of a running meter. The easiest way to find this value is in the GOST assortment reference table, however, there may be inaccuracies due to the density of the metal.

To independently calculate the mass of beams, you need to take into account the indicators of the areas of the shelf and wall, the density of steel. To determine the distance between the shelves, you should be guided by the formula: L = h-2 × t. The shelf area is calculated in accordance with the mathematical expression: S_P = b × t. To determine the wall area, we use the formula: S_FROM = L × S. To calculate the cross-section - S = Sс + 2 × Sп. The obtained cross-sectional index should be multiplied by the average density of steel, which is equal to 7850 kg / m³. All data must first be converted into square meters.S - profile wall thickness, h - beam height, b - flange size, t denotes the average flange thickness, L - rolled length.

Helpful advice! To simplify the calculation process and save time, you can use the I-beam calculator.
