In the construction of industrial and domestic buildings, one of the necessary materials are channels and steel beams. These metal products differ in the type of manufacture, length, thickness and other important parameters.
The steel beam is used in the construction of ceilings, columns, in the construction of bridges, supports, roads. Steel I-beams are made in two ways – welded or rolled. This design has the most optimal cross-sectional shape for bending work. According to the general classification, the following are distinguished:
Bridges with a slope.
For rolling, I-beams can be of ordinary accuracy and increased. They also differ in width and length. In width, they can be narrow-shelf, columnar, standard, medium-shelf, wide-shelf, with a slope. During production, beams are marked with initial letters.
Depending on the scope of use, a steel beam can also have different lengths – dimensional, non-dimensional, multiple dimensional. Reliability and practicality are determined by the length, method of fastening, cross-sectional area and type of cross-section. Sometimes reinforcement of the I-beam is required and in this case additional elements are welded.
If you are interested in an I-beam, you can buy a design from us. At the same time, consider the scope of use and select beams according to requirements.
The channel in cross section resembles the letter “P”, it can be of different sizes.
First of all, it is worth highlighting hot-rolled and cold-rolled. Also, according to the type of manufacture, they can be special, bent equal-shelf and bent unequal-shelf.
Distinguished by scope. Three groups can be distinguished:
· For car building;
for wagon building.
Such metal structures are indispensable in construction and industry. They are needed when reinforcing buildings, for the manufacture of frames, ceilings, road surfaces, bridges. They are also indispensable in the construction of multi-storey buildings. In this case, they are used in the creation of spans, in the construction of windows, roofs, as a reinforcement of concrete mortar.
All channels must be manufactured in accordance with GOST. Their quality and reliability depend on this, the parameters can be viewed in special tables. If you need to purchase high-quality and reliable products, buy them only from trusted manufacturers and suppliers. We offer our customers only high-quality products that exactly meet all the requirements and established standards. We offer a wide range of metal products at reasonable prices, we provide delivery and give all the necessary guarantees.
