Steel beams are an essential element of any construction. They serve to distribute loads in structures and are metal beams located in an inclined or horizontal position.
Steel beams can be T-shaped, I-shaped, hollow, and angular.

T-beams are made of low-alloy steel both by rolling and welding methods. They got their name due to the cross-section in the shape of the letter T.
Tow beams are actively used in the construction of various structures, as they are part of the supporting structure.
They allow you to reduce construction costs (due to the relatively low cost), help to increase the spans in the building and reduce the time spent on installation and construction work.
The T-beam is used to assemble crane beams and overhead cranes. It is also indispensable for the construction of garden greenhouses, balcony glazing, shelving and various equipment.
I-beam
It has an H-shaped cross-section and is made of low-alloy carbon steel by hot-rolled or welded method.
In construction, I-beams are most widely used to overlap structures subject to high bending loads. It is also used for the construction of large-panel facilities and attachments.
The sides of the I-beam can be positioned parallel or obliquely.
Beams with parallel faces can be:
Wide-brimmed. They serve as guides in heavy structures; they are normal. They are designed to create beam formwork; Columnar. They have massive shelves and lintels, and are used for building columns.
Beams with inclined faces are divided into:
Ordinary (with a slope of 6-12%) - marked with the letter B; Special (with a slope of no more than 20%) - marked with the letter M; Special (with a slope of no more than 16%) - marked with the letter C.
Beams with inclined faces are used in the construction of suspended structures, as well as to strengthen mine shafts.
Hollow beam
Hollow or box-shaped steel beams have a trapezoidal or rectangular cross-section. They have a high resistance to torsion, unlike traditional T-beams. Transverse diaphragms inside the box girder protect it from bulging walls.
Hollow beams are needed mainly in the construction of bridges. The metal sections are factory-cast and added one to the other.
Corner beam
Corner beams are used for building formwork. They form the inner and outer sides of the right angle of the wall of the structure.
Manufacturing technology
Steel beams are made in two ways: by rolling and by welding.
Hot-rolled beams assume the operation of a rolling mill through which a metal billet is passed.
The production of beams by welding involves cutting a metal sheet and welding individual elements.
The dimensions of the hot-rolled and welded beams are identical and comply with GOST 26020-83. Modern equipment makes it possible to produce welded beams that are not inferior in quality to rolled beams.
In addition, the beam produced by welding allows you to combine several types of steel (high-carbon and low-carbon), which reduces the cost.
If holes, cutouts and perforations on the beams are required, then this can only be achieved by welding.
Welded or rolled beams are high-strength building materials for industrial, residential, agricultural and public buildings. Best porn site
