Rebar

Threaded steel, also known as ribbed steel bar, is a hot-rolled strip steel with spiral ribs on the surface. Made mainly from carbon structural steel or low-alloy structural steel through hot rolling, it is one of the most widely used core building materials in construction projects with the largest dosage. With excellent mechanical properties and adaptability, it serves as a core load-bearing material for various building structures.
The core feature of threaded steel is the uniform longitudinal and transverse ribs on its surface. This special structure can greatly enhance the bond strength with concrete, effectively preventing relative sliding between steel and concrete, and improving the stability and load-bearing capacity of the overall structure. Compared with ordinary smooth round steel bars, it has better tensile and shear resistance, suitable for various load-bearing scenarios.
In terms of material, threaded steel mainly adopts grades such as Q235, HRB400 and HRB500. Among them, HRB400 grade threaded steel has become the mainstream choice for construction projects due to its moderate strength and high cost performance. It can be divided into different specifications (such as Φ12, Φ16, Φ20, etc.) according to project needs to meet the construction requirements of different spans and load-bearing levels. In the production process, hot rolling is mostly used, and some high-end threaded steel will be added with anti-corrosion treatment to further improve weather resistance and service life.
In terms of application scenarios, threaded steel is widely used in various construction projects, especially in large-scale infrastructure, real estate, bridges, tunnels, water conservancy projects and other fields. It is often used as core load-bearing components such as beams, columns, floor slabs and foundations to build the main frame of buildings. At the same time, it is also used in the load-bearing structures of industrial plants, energy facilities, rail transit and other projects. With good processability, it can be cut, bent and welded according to construction needs to adapt to the installation requirements of different projects.
In addition, threaded steel has strong quality stability, and its compression and tensile properties meet national construction standards. It has a complete range of specifications and sufficient supply. Its price fluctuates under the influence of raw materials and market supply and demand, showing strong market resilience as a key basic material supporting the high-quality development of the construction industry.
