Steel T-beam: characteristics and production A steel T-beam or steel T-beam is a type of shaped metal rolling, which is characterized by a T-shaped cross-section. The main task performed by a steel T-beam is to strengthen industrial and large-panel building metal structures (floors, staircases), as well as during the construction of bridges, supports and other industrial structures.
For the manufacture of steel brands, carbon, structural alloyed and unalloyed steel grades are used, which are characterized by high strength, good weldability, sufficient resistance to corrosion and oxidation processes. Among the most popular brands are S235JR / 1.0038, S275J2 / 1.0145, S355J0 / 1.0553, S355J2 / 1.0577, S355NL / 1.0546, S355ML / 1.8834, S355JR / 1.0045, S275J0 / 1.0143, S275NL / 1.0491, 1.19ML
The technological process for the production of a T-beam consists in multi-head welding of pre-cut and assembled components, followed by straightening.
It should be noted that a steel T-beam is a rather atypical rolled metal product, the production of which is not massive.
Tolerances, materials, markings, delivery conditions, as well as the dimensions of the T-beam are regulated by the EN 10055 standard.
The main technical parameters for the steel brand are: - width - from 25 to 140 mm;
- height - from 20 to 140 mm;
- wall thickness - from 3 to 15 mm;
- shelf thickness - from 3 to 15 mm.
These parameters must be known exactly in order to correctly select and order a T-beam that will fully meet the task at hand.
Depending on the size of the shelves, the T-beam can be of the T-type - equal-shelf T-bar and the TV-type - uneven-shelf T-bar. The latter is most often a stainless steel unequal T-beam.
The type of steel brand is selected taking into account the engineering needs of the metal structure in which this product is planned to be used.
