1. Grades and Standards

Standards: ASTM A615, ASTM A706, BS 4449, ISO 15630, JIS G3112.

2. Dimensions and Tolerances

• Diameter Range: 6mm to 50mm

• Length: 6m to 18m (standard), custom lengths up to 24m

• Rib Design: Transverse ribs with precise spacing and height per ISO 15630-1

• Tolerances:

  • Diameter: ±0.3mm (≤16mm), ±0.5mm (>16mm)

  • Weight: ±4.5% per bundle

  • Straightness: ≤2mm/m

3. Surface Treatments

• Plain Rebar: Black steel for general construction.

• Epoxy-Coated Rebar: 200–300μm coating for corrosion protection in marine/coastal areas.

• Galvanized Rebar: Zinc-coated for moderate corrosive environments.

• Rust-Inhibited Rebar: Temporary protection for short-term storage.

4. Mechanical and Chemical Properties

Chemical Composition (Grade 60 Example):

• Carbon (C): ≤0.30%

• Manganese (Mn): ≤1.20%

• Phosphorus (P): ≤0.035%

• Sulfur (S): ≤0.040%

Bend Test Performance:

• Rebars withstand bending to 180° without cracking (mandrel diameter = 4× bar diameter).

Quality Assurance

• Raw Material Testing: Spectrometry to verify chemical composition.

• Dimensional Checks: Laser scanning for rib geometry and diameter accuracy.

• Mechanical Testing: Tensile, bend, and rebound hardness tests.

• Certifications: ISO 9001, CE, and third-party inspection support.

Applications

• Infrastructure: Bridges, tunnels, dams, and highways.

• Buildings: Skyscrapers, residential complexes, industrial warehouses.

• Special Projects: Nuclear plants, seismic-resistant structures, underwater foundations.

Packaging and Logistics

• Bundling: Waterproof steel straps, 2–3 tons per bundle.

• Delivery: Global shipping with on-time guarantees.
