What is section steel? Is the steel bar a section?

Section steel is a kind of strip steel with a certain section shape and size. It is one of the four major types of steel (plate, tube, type and silk). According to the shape of the section, the section steel can be divided into simple section steel and complex section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, Angle steel, hexagonal steel, etc.; The latter refers to I-beam steel, channel steel, rail, window steel, bending steel, etc.

Rebar is not section steel, rebar is wire. Rebar refers to steel for reinforced concrete and prestressed reinforced concrete, and its cross section is round or sometimes square with rounded corners. Including round steel bar, ribbed steel bar, torsion steel bar. Reinforced concrete steel bar refers to the straight bar or disk bar steel used for reinforced concrete reinforcement, its shape is divided into two kinds of round steel bar and deformed steel bar, the delivery state is straight bar and disk round two.

Steel is widely used and there are many varieties. According to the different section shapes, steel is generally divided into four categories: profile, plate, pipe and metal products. Steel is a material of a certain shape, size and properties made from ingot, billet or steel by pressure working. Most steel processing is through pressure processing, so that the processed steel (billet, ingot, etc.) produce plastic deformation. According to the different steel processing temperature, can be divided into cold processing and hot processing two.
