Columned I-beams are a novelty in the field of rolled metal, which quickly became widespread. Such popularity is due to the fact that the characteristics of these structures allow them to be used in the most severe climatic conditions.
Description of products
Columned I-beam is a metal structure, which is one of the varieties of long products with an H-shaped profile of the transverse type. This product is made of unalloyed metal of fairly high quality. However, structural steel, characterized by low alloying, as well as high strength, can also be used. For the production of columned I-beams, hot rolling is used, the procedure of which is carried out on steel rolling mills. Currently, there is a general classification and labeling. According to this document, such products are marked with the letter "K", and all requirements for the quality of the material and the process of its production are prescribed in GOST 26020-83.
Different from other I-beams
The I-beam column type has some differences from any other variations of this product. Mainthe difference lies in the fact that the wall thickness of the columns is much higher than that of other models. Thanks to this, we can say with confidence that the strength and rigidity of this product is much higher. In addition, it significantly expands the scope of its use. However, there is also a downside here. As the wall thickness increases, so does the mass of one column.
For example, an I-beam in cross section equal to 30 cm marked "B" will weigh about 33 kg. But if we take the same section for the column type, then its mass will be about 87 kg (twice as much). One of the distinguishing features lies also in the fact that the beam faces can be located at different angles. This means that it is possible to change it for each application, which will further increase the strength and rigidity of the structure on an individual basis.
One of the main differences and advantages of this type of beams is a well-designed junction. This allows the beams to cope not only with static loads, but also with dynamic ones. This type of load can arise due to a variety of factors. This feature has led to the fact that columned I-beams have been successfully used in areas where there is increased seismic activity.
Application benefits
The number of positive aspects of this product is quite large, but there are several main ones among them.
- The first and most significant advantage is the large number of industries in which you canuse these designs.
- The second positive quality is, of course, the high level of strength and rigidity that an I-beam has.
- Due to the fact that each product can withstand a large load, the total number of supports can be reduced, which saves a significant amount of material.
- Very high mechanical resistance.
- The service life of columned I-beams is quite long.
- These metal structures are completely immune to attack such as chemical or biological.
- There is the possibility of butt-to-butt welding of the structure. This speeds up the editing process quite a lot.
You can also add that the length of the finished product ranges from 4 to 12 m.
Cost and application
The use of I-beams according to GOST 26020-83, which are made of high quality metal, is quite wide. It is worth noting that the material is considered new in the construction market, because its scope is constantly growing. Currently, this building material has found its greatest application in the construction of columns and vertical supports, which are installed in residential or industrial facilities. However, the production of other types of load-bearing structures from this material is also in demand.
If we talk about the pricing policy of this product, it is surprisingly modest. Although the spectrum of useI-beams according to GOST 26020-83 is very wide, its price is low. For example, the price for one ton of ready-to-use equipment is approximately from 39,000 to 51,000 rubles. At this price, you can purchase a similar design of any type.
