Details

Tianjin Shunchen Industrial's Rebar Coil is a rolled steel product made by continuously rolling hot-rolled round steel bars and ribbed steel bars, and then coiling them into a fixed diameter coil. The diameter covers 6mm~14mm, and the core materials include HPB300 round steel and HRB400, HRB500 high-strength threaded steel, which are the core basic steels in the fields of construction and infrastructure.

Its mechanical properties are stable, with HRB400 yield strength ≥ 400MPa and HRB500 yield strength ≥ 500MPa. It has excellent tensile performance and meets the safety standards for building structures. HPB300 is suitable for secondary stress scenarios, while high-strength materials meet the stringent requirements of the main structure and foundation load-bearing.

After straightening, cutting, and hooking processing, Rebar Coil can withstand tensile and compressive forces in concrete structures, enhancing the crack resistance and bearing capacity of components. The rolled shape facilitates bulk transportation and storage, reduces site occupation, and is compatible with automated processing equipment. The cut is flat and the size is precise, without the need for secondary trimming, greatly improving construction efficiency.

The Rebar Coil can be used in conjunction with customized embedded steel plates and bolts to enhance the structural integrity of building foundations, beams, columns, and other parts. Processed into different length specifications as needed, suitable for various scenarios such as building curtain walls and photovoltaic support foundations, with a wide range of applications.

Relying on the resources of Tianjin Iron and Steel Industry Base, mass production ensures timely supply. The product surface is free of oxidation and rust, with strong quality consistency and outstanding stable supply capability. By choosing Shunchen Industrial, you can enjoy one-stop procurement services that integrate production and sales, with sufficient support provided by 10000 yuan of liquidation.

Application Fields and Cases

（1） Photovoltaic supporting infrastructure field

Core application: Adapt to the reinforcement of photovoltaic power stations and photovoltaic carport foundations, collaborate with embedded bases and solar brackets to enhance the load-bearing capacity of the foundation, withstand wind and snow loads, and ensure the stability of the photovoltaic system.

Typical case: A photovoltaic logistics park project in Shandong Province uses HRB400 steel coil (diameter 12mm), which is automatically straightened, cut and processed, and used for pre embedded foundation reinforcement of roof photovoltaic brackets. The yield strength of steel bars is ≥ 400MPa, and the processing dimensional accuracy is ≤± 5mm/10m. It is used in conjunction with embedded steel plates and high-strength supports, with a total weight of 280 tons, effectively strengthening the foundation's tensile bearing capacity, ensuring that the photovoltaic system can withstand wind resistance of level 12 and snow load resistance of ≥ 0.7kN/m2, and is suitable for long-term outdoor operation needs.

（2） Industrial plant construction field

Core application:Rebar Coil is used for reinforcing beams, columns, floors, and foundation of factory buildings, combined with customized embedded components, to enhance the overall integrity and load-bearing capacity of the factory building structure, and to meet the load requirements of industrial equipment operation.

Typical case: A construction project of an electronic factory in Jiangsu Province used HPB300 (diameter 8mm) and HRB400 (diameter 14mm) steel bar coils, which were respectively used for hoop reinforcement and main beam column reinforcement. The surface is free of oxidation and rust, and after processing, it is installed in conjunction with pre embedded steel plates, with a welding qualification rate of 99.5% and a usage of 350 tons. It not only meets the heavy load bearing requirements of factory equipment, but also adapts to large-scale construction, shortens the construction period by 25%, and complies with the design specifications for concrete structures.

（3） Municipal infrastructure field

Core application: Rebar Coil is suitable for urban roads, bridge ancillary facilities, and underground pipe gallery foundation reinforcement, requiring high strength, corrosion resistance, and adaptability to complex working conditions to ensure the durability of infrastructure projects.

Typical case: A government pipe gallery project in a certain city in Tianjin, customized HRB500 high-strength steel coil (diameter 10mm), yield strength ≥ 500MPa, tensile strength ≥ 630MPa, meeting the long-term underground humid environment use requirements of the pipe gallery. After waterproof packaging and transportation, it is processed and reinforced with pre embedded bolts, with a dosage of 190 tons, effectively improving the crack resistance and bearing capacity of the pipe gallery structure, meeting the municipal engineering acceptance standards, and ensuring the safe operation of the pipe gallery.
