Welded Mesh
High-Strength Reinforcement Steel for Concrete Structures, EPC Projects & Infrastructure Engineering
Reinforcing Bar, also known as Steel Bar or Rebar, is a high-strength steel product widely used to reinforce concrete structures and improve their load-bearing capacity, durability, and resistance to cracking. Manufactured from premium carbon steel with strict quality control, our reinforcing bars are available in various diameters, grades, and surface finishes to meet international construction requirements. Suitable for residential buildings, commercial projects, bridges, roads, and infrastructure applications, we provide reliable supply, customized specifications, and professional support for global contractors, distributors, and engineering projects.
Tensile Strength
Ensures the structure can withstand pulling forces without failure.
Yield Strength
Defines the safe load limit used in structural design calculations.
Elongation
Improves earthquake resistance and structural flexibility.
Bonding Performance
Deformed ribs increase concrete bonding strength by improving mechanical interlock.
Our steel rebar is manufactured under strict international construction standards to ensure consistent mechanical performance, dimensional accuracy, and structural reliability for EPC and infrastructure projects.

3. Chemical Composition Control
To ensure stability and weldability, strict chemical composition control is applied:
● Carbon (C): 0.20% – 0.25%
● Silicon (Si): 0.40% – 0.80%
● Manganese (Mn): 1.20% – 1.60%
● Sulfur (S): ≤0.045%
● Phosphorus (P): ≤0.045%
4. Surface & Production Standards
● Surface Type: Deformed ribbed / smooth round bar
● Rib design improves concrete bonding strength by 30%+
● Production process: Hot rolling / cold processing / heat treatment
● Standard compliance:
● GB/T 1499.2
● ASTM A615
● BS 4449
● EN 10080
● ISO 6935
5. Product Identification & Traceability
Each rebar bundle includes permanent identification markings:
● Manufacturer code
● Grade (e.g., HRB400E)
● Diameter specification
● Heat number / batch number
☞ Example: HRB400E 25
Indicates seismic-grade 25mm deformed rebar with full traceability for EPC compliance.
☞ All specifications can be customized according to EPC project drawings and structural requirements.
