H-shaped steel is a new type of economic construction steel. The section shape of H-beam steel is economical and reasonable, the mechanical properties are good, the section points on the rolling section extension is more uniform, the internal stress is less, and compared with ordinary I-beam steel, it has the advantages of large section modulus, light weight and metal saving.

Wire rod, also known as wire rod, usually refers to small diameter round steel in coils. The diameter of the wire rod is in the range of 5-19 mm (usually 6-9 mm), and its lower limit is the minimum size of the hot rolled steel section.Steel bars are mainly subjected to tensile stress in concrete. Due to the action of the rib, the deformed steel bar has greater bonding capacity with the concrete, so it can better withstand the action of external forces.

Carbon black spring coil steel wire may refer to a spring coil steel wire whose surface treatment or additives contain carbon black related substances. Carbon black may remain on the surface of the steel wire as a lubricant, which plays a lubricating role in the manufacturing process such as steel wire drawing, reduces friction, prevents scratches on the surface of the steel wire, and helps to improve the surface quality and processing performance of the steel wire.

Carbon steel wire is a kind of steel wire containing a higher proportion of carbon elements, according to its carbon content, can be divided into high carbon steel wire, medium carbon steel wire and low carbon steel wire. High carbon steel wire after proper heat treatment or cold drawing hardening, with high strength and hardness, high elastic limit and fatigue limit, mainly used in the manufacture of springs and wear-resistant parts
