Rebar Steel Bar
Tianjin Shunchen Industrial's Rebar Steel Bars are strip-shaped building steel products formed by heating high-quality steel billets (usually 1000 ℃~1250 ℃) and then hot rolling, cold rolling or heat treatment processes. They are divided into round steel bars, ribbed steel bars (threaded steel bars), etc. according to their appearance, with a diameter range of 6-50mm. They are the core load-bearing material of concrete structures. It combines high strength, high toughness, and good weldability, and can be directly used for reinforced concrete reinforcement, suitable for multi scenario construction such as buildings, bridges, and water conservancy. It has outstanding cost-effectiveness and meets national building safety standards, making it an indispensable core building material for infrastructure projects.
Shunchen rebar steel bar is a core load-bearing steel material for reinforced concrete structures, manufactured from low-alloy and plain carbon steel through hot rolling, cold rolling or waste-heat treatment. It is supplied in diameters of 6–50 mm and standard lengths of 9 m or 12 m, covering plain round bar HPB300, hot-rolled ribbed bars HRB400 / HRB500, seismic grades HRB400E / HRB500E, and cold rolled ribbed bars CRB550 / CRB650. With stable mechanical properties, 0-grade bonding performance and full compliance to GB/T 1499 series standards, it suits beams, slabs, columns, shear walls, bridge piers, pile foundations and industrial equipment foundations.

Product Details
Tianjin Shunchen Industrial's Rebar Steel Bars are made from low-alloy steel and plain carbon steel as raw materials, which are heated, rolled, cooled (or subsequently heat-treated) by steel billets. According to the production process, they are divided into hot-rolled steel bars, cold-rolled ribbed steel bars, and waste heat treated steel bars. According to their appearance, they can be divided into round steel bars (smooth surface) and ribbed steel bars (with longitudinal and transverse ribs on the surface, including threads, crescent ribs, etc.). The diameter of steel bars is usually 6-50mm, and the length is mostly 9m or 12m (can be customized according to needs). It is the most widely used core load-bearing component in construction engineering.
The core value of Rebar Steel Bars lies in their collaborative work with concrete, utilizing their excellent tensile strength to compensate for the insufficient tensile performance of concrete. At the same time, with good bonding properties, they are tightly integrated with concrete to jointly withstand external forces such as building structure loads and earthquakes. The product has stable mechanical properties, with strict compliance with national standards for yield strength, tensile strength, elongation, and other indicators. It can be adapted to various installation methods such as binding, welding, and mechanical connection, and can meet the construction needs of different structural forms. It is a key material to ensure the safety and durability of construction projects.
The production process of Rebar Steel Bars is mature, large-scale production reduces unit costs, and the cost-effectiveness far exceeds that of similar load-bearing materials; The specification system is complete, covering all aspects from fine diameter stirrups to coarse diameter main reinforcement, adapting to the needs of different structural parts; Excellent seismic performance, with seismic grade steel bars (Grade E) designed through special processes, which can delay plastic deformation under earthquake action and enhance the seismic resistance of the structure; The green and environmentally friendly attributes are prominent, and the production process adopts waste heat recovery, energy-saving and emission reduction technologies. Some products can be smelted through recycled raw materials, which is in line with low-carbon building policies.
