Reinforcement is not steel, but silk. Rebar refers to the steel used in reinforced concrete and prestressed reinforced concrete, and its cross section is round, sometimes square with rounded corners. Include round steel, ribbed steel bar and torsion steel bar. Steel bars for reinforced concrete refer to straight steel bars or rolled steel bars used to strengthen reinforced concrete. Its shape can be divided into smooth circular reinforcement and deformed reinforcement, and the delivery state is straight and coiled. ?

Section steel classification
1. Large section steel: I-beam, channel steel, angle steel and flat steel in large section steel are all hot rolled, while round steel, square steel and hexagonal steel are not only hot rolled, but also forged and cold drawn.
2. I-beam, channel steel and angle steel are widely used in industrial buildings and metal structures, such as factories, bridges, ships, agricultural machinery and vehicles, transmission towers, transportation machinery, etc. They are often used together. Flat steel is used as bridges, housing frames, fences, power transmission boats and vehicles on construction sites. Round steel and square steel are used as various mechanical parts, agricultural machinery accessories and tools.
3. Medium-sized steel: The use of medium-sized steel such as I-beam, groove, angle, round and flat steel is similar to that of large-sized steel.
4. Small-sized steel: The processing and use of corner, round, square and flat steel in small-sized steel are similar to those in large-sized steel, and small-diameter round steel is often used as building reinforcement.
