Steel wire ropes are standard products in various industrial countries, and their diameter, number of strands, number of steel wires per strand, tensile strength, and sufficient safety factor can be selected according to their usage needs. Their specifications and models can be found in relevant manuals. In addition to the wear of the outer steel wire, the steel wire rope gradually breaks due to metal fatigue caused by repeated bending around the pulley and drum. Therefore, the ratio of the diameter of the pulley or drum to the diameter of the steel wire rope is an important factor determining the service life of the steel wire rope. The ratio is large, the bending stress of the steel wire is small, the service life is long, but the mechanism is huge. The appropriate ratio must be determined based on the usage situation. When the wear and corrosion degree of the surface layer of the steel wire rope or the number of broken wires within each twist exceeds the specified value, it should be scrapped.
Steel wire ropes are mainly used in transportation that requires high-strength wire ropes, such as lifting and pulling.

Pre stressed steel strands are stranded steel cables composed of 2, 3, 7, or 19 high-strength steel wires, which have undergone stress relief treatment (stabilization treatment) and are suitable for prestressed concrete and similar applications.
The main characteristics of prestressed steel strands are high strength and good relaxation performance, and they are also relatively straight when unfolded. The common tensile strength grades are 1860 megapascals, as well as strength grades such as 1720, 1770, 1960, 2000, 2160, 2230, and 2360 megapascals. This type of steel also has a high yield strength.

Steel wire is one of the four major varieties of steel: plate, tube, section, and wire. It is made by using hot-rolled wire rods and cold drawing them
Processed products. Classified by cross-sectional shape, there are mainly circles, squares, moments, triangles, ellipses, flattened, trapezoids, Z-shaped, etc; According to size classification, there are ultra-fine<0.1mm, relatively fine 0.1-0.5mm, fine 0.5-1.5mm, medium 1.5-3.0mm, coarse 3.0-6.0mm, relatively coarse 6.0-8.0mm, and ultra-coarse>8.0mm; According to strength classification, there are low strength<390 megapascals, lower strength 390-785 megapascals, normal strength 785-1225 megapascals, higher strength 1225-1960 megapascals, high strength 1960-3135 megapascals, and ultra-high strength>3135 megapascals

Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete, with a circular cross-section and sometimes a square with rounded corners. Including round steel bars, ribbed steel bars, and twisted steel bars.
Steel bars for reinforced concrete refer to straight or coiled steel bars used for reinforcement of reinforced concrete. Their appearance is divided into two types: smooth round steel bars and deformed steel bars, and the delivery status is straight and coiled.

Hot rolled coils are made from continuously cast or initially rolled slabs, heated by a stepper heating furnace, descaled by high-pressure water, and then fed into a roughing mill. The roughed material is cut, tailed, and then fed into a finishing mill for computer-controlled rolling. After final rolling, it is cooled by laminar flow (computer-controlled cooling rate) and taken up by a coiler to become a straight coil.

Cold rolled thin sheets, also known as CRS. CRS is made of hot-rolled steel. The cold rolling process helps to obtain cold-rolled thin sheets from the cooling of hot-rolled pickled products (made of the highest quality steel) in the cold rolling mill. These hot-rolled pickled products reduce thickness to a finer degree through strain hardening (up to nearly 20%), thereby improving strength. Compared with the thin plate formed during the hot rolling process, the cold-rolled thin plate obtained is smaller and has poorer ductility. They have better surface finish and smaller tolerances.

Seamless steel round tubing is primarily used for structural applications and is manufactured using extrusion, which involves piercing the center of a heated solid steel bar with a die. There are two types of round seamless steel tubing produced using this method: Cold Drawn Seamless (CDS) and Hot Finished Seamless (HFS).

Ductile iron pipes refer to pipes made by high-speed centrifugal casting using a centrifugal ductile iron machine after adding a spheroidizing agent to cast iron of grade 18 or above. They are commonly referred to as ductile iron pipes, ductile iron pipes, and ductile iron pipes. Mainly used for the transportation of tap water, it is an ideal choice material for tap water pipelines.
