1、 Rebar
Rebar is the rebar with ribs on the surface, also called Ribbed Rebar. It usually has two longitudinal ribs and transverse ribs evenly distributed along the length direction. The rebar is divided into grade I rebar (round steel), grade II rebar (hrb235), grade III rebar (HRB400) and grade IV rebar (HRB500). Due to the role of ribs, the rebar and concrete have a large bonding capacity, so they can better withstand the external force. Rebar is used in civil works such as houses, bridges and roads, and public facilities such as highways, railways, tunnels, flood control and dams.
2、 Wire
Wire rod refers to hot-rolled round steel with a diameter of 5-22mm. It is also called wire rod because it is traded in the form of coil in the market. The diameter of commonly used wire products is 5-13mm. The wire is also widely used. In addition to directly acting on the building reinforcement, it can also be processed into various special steel wires, such as spring steel wires, communication wires, and other metal products, such as rivets and nails.
3、 Round steel
Round steel refers to the solid long steel with circular section. The specification is expressed in millimeters of diameter. For example, "40" means round steel with a diameter of 40mm. Round steel is used in many aspects, such as hardware, architecture, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy and aerospace.
4、 Galvanized steel pipe
Welded steel pipes with hot dip or electro galvanized coating on the surface of galvanized steel pipes. Galvanizing can prolong the service life of galvanized steel pipes and increase the corrosion resistance of steel pipes. Galvanized steel pipes are widely used in construction, machinery, coal mine, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, petroleum machinery, prospecting machinery and other manufacturing industries.
5、 Angle steel
Angle steel, also known as angle iron, is a long strip of steel whose two sides are perpendicular to each other and form a 90 degree angle. Angle steel is divided into equal angle steel and unequal angle steel. The two sides of the equilateral angle steel are equal in width. The specification is based on the side width × Side width × The side thickness is expressed in millimeters. Such as "∠ 20 × twenty × 4 ", i.e. equal angle steel with side width of 20mm and side thickness of 4mm.
Angle steel is widely used in various building structures and engineering structures, such as house beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers and container racks.
