Hemaokang Steel (Shandong) Co., Ltd. is a professional manufacturer and exporter of steel reinforcement products. We offer deformed steel rebar in 10mm, 14mm, and 18mm diameters that are specially engineered for heavy-duty concrete reinforcement in bridge piers and tunnel linings. Our rebar features a ribbed surface for superior mechanical anchorage, consistent dimensions for easy installation, and excellent weldability for flexible on-site processing. As a company with annual export value of US$50–100 million and 51–100 employees, we are dedicated to providing reliable reinforcing steel solutions for infrastructure projects worldwide.
Product Overview
Deformed steel rebar, also called reinforcing bar or rebar, is a key material in reinforced concrete structures. The deformations on the surface improve the bond between steel and concrete, preventing relative movement under load. This makes it ideal for load-bearing elements like bridge piers, tunnel linings, retaining walls, and other heavy civil engineering works. Our 10mm, 14mm, and 18mm bars are popular sizes that offer a good balance between structural strength and workability.
The rebar is produced from selected carbon steel through a controlled rolling process. This ensures a homogeneous metallurgical structure, stable mechanical properties, and consistent rib geometry. The bars can be supplied as straight bars or cut to length, with bending and detailing services available upon request. For special environments, additional corrosion protection such as epoxy coating or galvanization is available as an optional feature.
Key Features and Advantages
- Enhanced bond strength: The surface ribs create mechanical interlocking with surrounding concrete, significantly increasing pull-out resistance and reducing crack width in structural members.
- Reliable mechanical performance: The rebar is manufactured with controlled chemical composition to ensure good tensile strength, yield strength, and elongation. The properties can be customized to meet different design codes.
- Consistent quality: From raw material selection to final inspection, every step is monitored under the ISO9001 quality management system, ensuring uniform dimension and accurate chemical composition.
- Excellent weldability: The steel composition supports common arc welding and resistance welding methods, simplifying connections and installation in complex reinforcement cages.
- Outstanding ductility: The material demonstrates good bending performance, suitable for stirrups, hooks, and seismic detailing without cracking.
- Flexible lengths: Standard length is 6m or 12m, or custom lengths can be produced according to project drawings or shipping container requirements.
- Easy handling: Bars are supplied in bundles with clear labeling, and can be handled by conventional lifting equipment on site.

Applications
Deformed steel rebar is used in almost every concrete structure that must bear tension or bending forces. Our 10mm, 14mm, and 18mm bars are particularly suited for medium to heavy reinforcement. Common applications include:
- Bridge piers, abutments, and concrete substructures
- Tunnel lining segments, shotcrete support, and rock bolt reinforcement
- Foundation slabs, pile caps, and deep foundations
- Retaining walls, culverts, and drainage structures
- Highway pavement and airport runway slabs
- Precast concrete elements such as beams, columns, and panels
- Marine structures including harbor docks and seawalls
- Hydraulic concrete works like dams and water treatment tanks
In bridge piers, deformed rebar often forms dense reinforcement cages with stirrups and longitudinal bars, resisting both vertical and lateral loads. In tunnel linings, it provides the required tensile capacity to withstand ground pressure and seismic movements. These small to medium diameters offer flexibility for complex geometries while delivering high structural efficiency.
Quality Assurance and Compliance
Hemaokang Steel operates with a complete quality management system certified to ISO9001. Each production lot is inspected and tested to verify chemical composition, mechanical properties, and geometric dimensions. We can supply mill test certificates as well as performance reports according to the specified standard.
To ensure your reinforcement project stays on schedule, we maintain a stable production line and flexible logistics. Orders can be handled from small quantities to large project volumes. Third-party inspection, such as SGS or BV, can also be organized at the buyer’s request.
Packaging and Shipping
Rebar bundles are tightly strapped with steel strips and protected with waterproof paper or plastic film to prevent contamination during sea transportation. Standard export packing suits container shipping or bulk vessel loading. We ship from Qingdao Port, offering good ocean freight access to major regions across the world. Detailed packing lists and loading photos are provided before shipment.
