Column I-beams are a novelty in the field of metal rolling, 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.
Product Description
Column 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 level strength can be used. Hot rolled steel is used for the production of columned I-beams, the procedure of which is carried out on steel mills. There is currently 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.
Unlike other I-beams
The column type I-beam has some differences from any other variations of this product. The main 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 stiffness of this product is much higher. In addition, this significantly expands the scope of its use. However, there is a certain minus. With increasing wall thickness, the mass of one column also increases.
For example, an I-beam in cross section equal to 30 cm marked "B" will weigh about 33 kg. But if you 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 individually.
One of the main differences and advantages of this type of beams is a competently designed interface. This allows the beams to cope perfectly not only with static loads, but also with dynamic ones. This type of load can occur due to a variety of factors. This feature has led to the fact that columnar 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 among them several main ones can be distinguished.
- The first and most significant advantage is the large number of industries in which these structures can be used.
- The second positive quality is, of course, the high level of strength and stiffness that the 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 resources.
- Very high resistance to mechanical stress.
- The life of the columned I-beams is quite large.
- These metal structures are completely immune to such types of exposure as chemical or biological.
- There is the possibility of welding the construction of the joint in the joint. This pretty much speeds up the installation process.
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 the scope of its application is constantly growing. Currently, this building material has found the greatest application in the construction of columns and supports of the vertical type, which are installed in residential or industrial buildings. However, the production of other types of supporting structures from this material is also quite in demand.
If we talk about the pricing policy of this product, then it is surprisingly modest. Despite the fact that the range of use of I-beams according to GOST 26020-83 is very wide, its price is low. For example, the price per ton of equipment ready for operation is approximately 39,000 to 51,000 rubles. At this cost, you can purchase a similar design of any type.
