    There are many types of steel, which can generally be classified into four categories: profile, plate, tube and wire. 1. There are many varieties of section steel, which is a kind of solid strip steel with a certain cross-sectional shape and size. According to the different cross-sectional shapes, it is divided into two types: simple and complex cross-sections.

    The former includes round bars, square bars, flat bars, hexagonal bars and angle bars; The latter includes rails, I-beams, channel steels, window frame steels and special-shaped steels. The diameter of the small round steel is called the wire. 2. Steel plates are divided into three types: thin plate (thickness <4mn), medium plate (thickness 4-25mn) and thick plate (thickness 25mm) according to different thicknesses.

    3. Steel pipe This is a kind of long steel with hollow section. According to its different cross-sectional shapes, it can be divided into round pipes, square pipes, hexagonal pipes and various special-shaped cross-section steel pipes. According to different processing technology, it can be divided into two categories: seamless steel pipe and welded steel pipe.

    According to the quality, it can be divided into ordinary steel, high-quality steel, high-grade high-quality steel, according to the chemical composition, it can be divided into carbon steel, low-alloy steel, according to the use, it can be divided into engineering steel, carburizing steel, carbon tool steel, special performance steel, etc., according to the forming method, it can be divided into forged steel, cast steel, hot-rolled steel, cold-drawn steel, etc.

    Steel is a material of a certain shape, size, and properties that ingots, billets, or steel are made by pressure processing.

    Most of the steel is processed by pressure, and can be divided into two types: cold working and hot working according to different processing temperatures.

    According to the different cross-sectional shapes, steel can generally be divided into four categories: profiles, plates, pipes and metal products.
