1、 Threaded steel

Threaded steel is a surface ribbed steel bar, also known as ribbed steel bar, usually with two longitudinal ribs and transverse ribs evenly distributed along the length direction. Among them, threaded steel is divided into Grade I threaded steel (round steel), Grade II threaded steel (HRB235), Grade III threaded steel (HRB400), and Grade IV threaded steel (HRB500). Due to the effect of ribs, rebar and concrete have a greater bonding ability, which enables them to better withstand external forces. Threaded steel is used in civil engineering projects such as houses, bridges, roads, as well as public facilities such as highways, railways, tunnels, flood control, and dams.

2、 Wire rod

Wire refers to hot-rolled round steel with a diameter of 5-22mm, also known as coil because it is traded in the market in the form of coils. The commonly used wire product specifications have a diameter of 5-13mm. The use of wire is also very extensive. In addition to directly acting on building steel bars, it can also be processed into various specialized steel wires, such as spring steel wires, communication wires, etc. It can also be processed into other metal products, such as rivets, iron nails, etc.

3、 Round steel

Round steel refers to a solid strip of steel with a circular cross-section. Its specifications are expressed in millimeters of diameter, such as "40" representing round steel with a diameter of 40 millimeters. Round steel is used in many fields, including hardware, construction, automotive, shipbuilding, petrochemicals, machinery, medicine, food, electricity, energy, aerospace, and more.

4、 Galvanized steel pipe

Welded steel pipes with hot-dip or electroplated zinc coating on the surface of galvanized steel pipes. Galvanizing can extend the service life of galvanized steel pipes and increase their corrosion resistance. Galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, petroleum machinery, and mining machinery.

5、 Angle steel

Angle steel, also known as angle iron, is a long strip of steel with two sides perpendicular to each other at a 90 degree angle. Angle steel is divided into two types: edge angle steel and unequal angle steel. The two sides of an equilateral angle steel have equal widths. Its specifications are expressed in millimeters of edge width x edge width x edge thickness. For example, "∠ 20 × 20 × 4" refers to an equilateral angle steel with a width of 20 millimeters and a thickness of 4 millimeters.

Angle steel is widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, and container racks.
