Product Features

Ribbed Surface for Concrete Bonding

The longitudinal and transverse ribs on the surface of the reinforcement bar help create mechanical interlocking between steel and concrete. This bonding mechanism supports load transfer within reinforced concrete structures and helps reduce relative movement between the reinforcing steel and the surrounding concrete when properly designed and installed.

Multiple Steel Grades for Structural Reinforcement

Shunchen supplies different grades of ribbed steel reinforcement bars to meet varying structural design requirements. HRB400 and HRB500 are used in conventional reinforced concrete applications, while HRB400E and HRB500E are seismic-grade options with additional ductility and strength-ratio requirements. The appropriate grade should be selected according to structural drawings, project specifications, and applicable building codes.

Consistent Mechanical Properties

The Ribbed Steel Reinforcement Bar for Building Projects production process includes billet heating, rolling, and controlled cooling or subsequent heat treatment according to the product type. Mechanical properties such as yield strength, tensile strength, elongation, and bending performance are evaluated against the applicable standard and specified steel grade. This helps construction teams select reinforcement materials that meet project design requirements.

Multiple Diameters and Length Options

The standard diameter range covers 6–50 mm, with 8–32 mm commonly used in building reinforcement. Standard lengths are 9 m and 12 m, while customized fixed lengths can be discussed for suitable orders. The available range supports different reinforcement requirements, from smaller-diameter bars used in secondary reinforcement to larger bars used in structural members.

Suitable for Seismic-Resistant Structures

HRB400E and HRB500E seismic-grade reinforcement bars are designed to meet additional ductility and yield-strength-ratio requirements under the relevant standard. These properties make them suitable for structural applications where seismic performance is specified. Final grade selection and placement should follow the project's structural design and local regulations.

Flexible Processing and Installation Compatibility

Ribbed steel reinforcement bars can be incorporated into reinforced concrete structures through approved construction methods, including tying, mechanical connection, and welding where permitted by the applicable grade and project specifications. For projects requiring prepared reinforcement, Shunchen also provides related cut-and-bend rebar solutions.

Product Structure and Manufacturing Process

Shunchen Ribbed Steel Reinforcement Bars are manufactured from carbon steel or low-alloy steel billets. The billets are heated and rolled through a series of rolling stands to form the required diameter and ribbed surface profile. Depending on the product grade and production route, controlled cooling or subsequent heat treatment may be applied to achieve the required mechanical properties.

The finished bars feature longitudinal ribs and transverse ribs along the surface. These ribs are designed to improve the mechanical bond between reinforcement and concrete. The bar diameter, length, rib geometry, surface condition, and mechanical properties are controlled according to the applicable product standard and order requirements.

After production, the bars are inspected, identified by grade and specification, and prepared for bundling and shipment. Product labels and relevant quality documentation help customers verify the supplied material against their purchase orders and project requirements.

Technical Specifications

Steel Grades and Applicable Standards

Different reinforcement grades are used according to structural design requirements, strength levels, ductility requirements, and applicable construction standards. The following table summarizes the main grades in Shunchen's reinforcement product range.

Other reinforcement products, including HPB300 plain round bars and CRB550 / CRB650 cold-rolled ribbed bars, are available within the broader product range. Their applicable standards and specifications should be confirmed separately according to the selected product type.

Dimensional Specifications and Theoretical Weight

Ribbed steel reinforcement bars are supplied in different diameters to meet the reinforcement requirements of structural members. The following theoretical weights are calculated using the commonly applied formula for steel reinforcement bars:

The values above are theoretical reference weights. Actual weight and dimensional tolerances are subject to the applicable product standard, nominal diameter, and inspection requirements. Please confirm the required specifications before ordering.

Quality Control and Testing

Shunchen applies quality inspection procedures throughout the reinforcement steel production and supply process. Inspection requirements are arranged according to the product grade, applicable standard, and order specifications to help ensure that delivered materials meet the agreed technical requirements.
