High-ductility HRB400 and HRB500 steel coils engineered for building construction, automated processing, and superior concrete bonding.
Seismic-Grade Deformed Rebar in Coil for Building Construction is specifically manufactured for use in reinforced concrete foundations, beams, columns, slabs, and critical infrastructure projects. The ribbed surface significantly improves mechanical bonding with concrete, while the continuous coil form supports highly efficient straightening, cutting, and bending with compatible processing equipment.
Key Features
Strength & Ductility
Available in HRB400 and HRB500 grades. Yield strength, tensile strength, and elongation strictly meet seismic design requirements, ensuring structural safety and energy dissipation during earthquakes.
Optimized Ribbed Surface
The precisely engineered transverse and longitudinal ribs provide exceptional mechanical interlocking with concrete, preventing slippage and reinforcing foundations, beams, and columns securely.
Continuous Coil Processing
Supplied in heavy-duty coils suitable for high-speed automated straightening, cutting, and bending. This drastically reduces material waste and improves on-site processing efficiency.
Flexible Specifications
Coiled rebar is available from 6–14 mm, while straight bars range from 6–50 mm (standard 9m/12m). Customized lengths and processing services are available upon request.

Application Fields
Photovoltaic Foundations
Deformed rebar is a critical component in reinforced concrete foundations for solar projects. The specific grade, diameter, and reinforcement layout are selected according to structural drawings to withstand wind and snow loads. Explore our photovoltaic support solutions for integrated sourcing.
Industrial Buildings
Extensively used in concrete foundations, ground beams, columns, and floor slabs for industrial facilities. The required steel grade and dimensions depend on structural design and loading conditions. Check our steel structure materials for complete building frameworks.
Municipal Infrastructure
Deformed reinforcing steel is essential for underground utility galleries, drainage structures, and service corridors. Proper concrete cover, waterproofing, and corrosion protection (such as hot-dip galvanizing) should follow project specifications. See our galvanized steel grating for related municipal products.

Frequently Asked Questions
What is seismic-grade deformed rebar?
Seismic-Grade Deformed Rebar in Coil for Building Construction is reinforcing steel specified for structures requiring defined strength and ductility performance under seismic (earthquake) design requirements. It typically features a more tightly controlled yield strength ratio and higher elongation to absorb seismic energy without brittle failure.
What diameters are available for rebar in coil?
Our listed coil diameter range is typically 6–14 mm. However, available diameters and coil specifications depend on current production availability. Please confirm with our sales team for your specific project needs.
Are straight reinforcing bars available?
Yes. Our straight bar diameter range is 6–50 mm, with standard lengths of 9 m and 12 m. We also support customized cutting lengths based on your drawings.
Is galvanized rebar available for coastal projects?
Yes, hot-dip galvanizing may be applied for suitable applications. The zinc coating specification (such as 80 μm) should be confirmed prior to ordering to ensure it meets the corrosion resistance requirements of your coastal or high-humidity project.
What information is needed to get a wholesale quotation?
To provide an accurate quotation, please provide the steel grade (HRB400/500), diameter, product form (coil or straight bar), estimated quantity, applicable standard, and delivery destination. Any specific testing or corrosion protection requirements should also be included.
