Carbon Steel Rebar

Name: Carbon Steel Rebar
SKU: 0

Carbon steel bars (also known as rebar or ribbed steel bars) are the most commonly used reinforcing material in concrete structures. Through the mechanical interlock created by their longitudinal and transverse ribs with the concrete, they effectively enhance the concrete’s tensile strength and the structure’s load-bearing capacity.
Carbon steel bars are characterized by high strength, low cost, and excellent workability, and are widely used in infrastructure projects such as buildings, bridges, roads, and water conservancy projects.

Product Advantages：

💪 High Load-Bearing Capacity

HRB500-grade rebar has a yield strength of ≥500 MPa, which is approximately 50% higher than that of HRB335. This allows for a 15–20% reduction in rebar usage, thereby lowering the structure’s dead weight.

🏗️ Excellent Bonding Performance

The design of transverse and longitudinal ribs creates a mechanical interlock with concrete, resulting in a bonding strength over 40% higher than that of smooth-surface rebar, effectively preventing slippage.

🔄 Good Workability

It can be bent, cut, welded, and mechanically connected (straight-threaded sleeve connections), making it suitable for various complex joint configurations.

🛡️ Multiple Corrosion Protection Options

Epoxy Coating: Corrosion resistance increased by 1,700 times, suitable for marine environments and de-icing salt environments

Hot-Dip Galvanizing: Suitable for outdoor temporary structures

Stainless Steel Cladding: For extreme corrosion environments

♻️ 100% Recyclable

An eco-friendly material that aligns with sustainable development principles.

💰 High Cost-Effectiveness

Carbon steel rebar costs significantly less than stainless steel rebar, making it the economical choice for large-scale projects.
