The following steel products are used in construction: sections, sheet metal, pipes, bars for concrete reinforcement, rolled bars, sheet metal products and special profiles. The figure shows the standard profiles of hot-rolled steel bars.
I-sections are mainly used as bending beams. Poles are made of T-bars, roof purlins and beams. The tees are manufactured in 2 types; high and low wide feet, whose height is equal 1/2 belt width. Z-profiles are most often used as roof purlins, due to the high stiffness in the direction of both axes of symmetry.
Angles are produced in two versions: isosceles and non-isosceles.
Beams are made of steel sheets (tinny) and columns most often with I-section or box sections.
In addition to the aforementioned range of steel products, welded I-beams are produced in steel mills, and in construction factories - openwork beams. In addition, cold-bent sections are made of sheets.
