Carbon steel coil: Mild steel (iron with a small amount of carbon, high strength, good toughness but not easy to temper), also known as regular carbon steel and mild steel, is currently the most common steel because of its relatively low price while providing material properties acceptable for many applications. Mild steel contains about 0.05–0.30% carbon[1], making it malleable and malleable. Mild steel has comparatively low tensile strength, but it is inexpensive and easy to form. Carburizing can improve the surface hardness.
Galvanized coil: A galvanized coil in which a thin steel sheet is immersed in a molten zinc tank so that a layer of zinc adheres to its surface. It is mainly produced by continuous galvanizing process, that is, the coiled steel plate is continuously immersed in the plating tank with zinc melted to make galvanized steel plate; Alloyed galvanized steel sheet. This steel plate is also made by the hot-dip method, but immediately after it is slotted, it is heated to about 500°C to form an alloy film of zinc and iron. This galvanized coil has good coating adhesion and weldability.
Color coated coil: Color coated coil is a product made of hot-dip galvanized sheet, hot-dip aluminum-zinc sheet, electro-galvanized sheet, etc., after surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic paint are coated on the surface, and then baked and cured. It is named because it is coated with a variety of different colors of organic paint color steel coil, referred to as color coating roll.
Steel pipe: Steel with a hollow section whose length is much larger than the diameter or circumference. According to the cross-sectional shape, it is divided into round, square, rectangular and special-shaped steel pipes; According to the material, it is divided into carbon structural steel pipe, low-alloy structural steel pipe, alloy steel pipe and composite steel pipe; According to the use, it is divided into steel pipes for transportation pipelines, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment. According to the production process, it is divided into seamless steel pipe and welded steel pipe, of which seamless steel pipe is divided into hot rolled and cold rolled (drawn), and welded steel pipe is divided into longitudinal welded steel pipe and spiral seam welded steel pipe.
Rebar: Rebar refers to steel for reinforced concrete and prestressed reinforced concrete, which has a circular cross-section and sometimes a square with rounded corners. Including round rebar, ribbed rebar, torsion rebar.

The steel bar for reinforced concrete refers to the straight bar or wire strip steel used for reinforced concrete reinforcement, and its shape is divided into two types: light round steel bar and deformed steel bar, and the delivery state is straight bar and disc round.

The light round steel bar is actually the small round steel and disc circle of ordinary low carbon steel. Deformed steel bars are ribbed steel bars with a surface, usually with 2 longitudinal ribs and transverse ribs evenly spaced along the length. There are three types of transverse ribs: spiral, herringbone, and crescent. It is expressed in millimeters of nominal diameter. The nominal diameter of the deformed reinforcement is equivalent to the nominal diameter of the light round reinforcement with equal cross-section. The nominal diameter of the reinforcement is 8-50 mm, and the recommended diameters are 8, 12, 16, 20, 25, 32, 40 mm. Steel grade: 20MnSi, 20MnV, 25MnSi, BS20MnSi. Reinforcing bars are mainly subjected to tensile stress in concrete. Due to the action of ribs, the deformed steel bar has a greater bonding capacity with concrete, so it can better withstand the action of external force. Steel bars are widely used in various building structures. Especially large, heavy, lightweight, thin-walled and high-rise building structures.
