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.
