Details

Tianjin Shunchen Industrial's Deformed Bar in Coil, also known as hot-rolled ribbed steel bars, has two longitudinal ribs and uniform transverse ribs distributed on the surface. The core materials are HRB400 and HRB500, with a diameter covering 6mm~50mm. It can be made into straight bars or coils and is the core steel material that bears tensile force in concrete components. Its transverse rib design is different from that of round steel bars, which can significantly enhance the grip force with concrete and avoid relative slip.As the core of structural stress, it is widely used in concrete beams, columns, foundations, floor slabs and other parts to transmit tension and pressure, enhance the bearing capacity and crack resistance of components. The size of the transverse ribs is regular and evenly distributed, and the bonding strength with concrete far exceeds that of round steel bars, further ensuring the overall integrity and stability of the structure.

The mechanical performance meets the national standard requirements, with HRB400 yield strength ≥ 400MPa and HRB500 yield strength ≥ 500MPa, and stable tensile and seismic performance. High strength materials and reliable performance can support the long-term safe operation of buildings and infrastructure projects, and adapt to complex working conditions.

Deformed Bar in Coil has a wide range of adaptability scenarios. The straight strip form can be directly used for on-site reinforcement, while the coiled form can be cut and processed for use, covering multiple fields such as photovoltaic infrastructure, industrial plants, and municipal engineering. Forming an integrated supply chain with Shunchen Industrial for cutting, processing, and embedded components, we can customize specifications as needed to achieve seamless integration of raw materials, processing, and assembly.

Deformed Bar in Coil can be used as raw material for steel coil cutting, and can also be assembled in conjunction with embedded components, compatible with various construction methods. There are no excess defects on the surface, the rib patterns are regular, and the dimensional accuracy after cutting is controllable. It can be put into use without complex trimming. Its collaborative and efficient characteristics are suitable for large-scale construction and personalized project requirements, providing stable and reliable reinforcement solutions for various types of projects.
