Product Introduction

High-Strength Carbon Steel Wire Rods: Hot-Rolled Precision for Construction & Industrial Use.‌

‌Multi-Grade Carbon Steel Wire Rods with Custom Coatings.‌

Engineered to ‌JIS G3466, EN 10219, and ASTM A53‌ standards, our carbon steel wire rods offer ‌330–550 MPa tensile strength‌ for scaffolding, fencing, and hydraulic systems. Available in ‌0.1–12mm wall thickness‌ (±5% tolerance) and ‌5–14m coil lengths‌, these rods reduce fabrication costs by 15–20% through precise dimensional control and anti-corrosion coatings.

‌Key Features‌:

  • ‌Grades‌: Q195, Q235, Q345, ASTM A53 GrA/GrB, STKM11, ST37, 16Mn
  • ‌Surface Options‌: Hot-dip galvanized (270g/m²), PVC-coated (0.4–1.2mm), or anti-rust oil
  • ‌Certifications‌: ISO 9001, RoHS, Mill Test Reports

‌Technical Specifications & Mechanical Properties‌

‌Material Grades & Performance‌

‌Grade‌ ‌Yield Strength‌ ‌Tensile Strength‌ ‌Elongation‌ ‌Carbon Content‌ ‌Standards‌
‌Q235‌ 235 MPa 370–500 MPa ≥26% ≤0.22% GB/T 3094, EN 10219
‌ASTM A53 GrB‌ 240 MPa 415 MPa ≥20% ≤0.30% ASTM A53, JIS G3466
‌ST52‌ 355 MPa 490–630 MPa ≥17% ≤0.20% DIN 17100, EN 10219

‌Dimensional Tolerances‌:

  • ‌Wall Thickness‌: 0.1–12mm (±5%)
  • ‌Outer Diameter‌: 5–200mm (±0.15mm)
  • ‌Coil Weight‌: 1–20 tons (customizable)
  • ‌Straightness‌: ≤1.5mm/m deviation

‌Applications Across Industries‌

  1. ‌Construction‌:
    • ‌Q235 (6–12mm)‌: Scaffolding pipes, rebar ties (≤0.25% sulfur for weldability)
  2. ‌Agriculture‌:
    • ‌Galvanized ST37 (8–14mm)‌: Greenhouse frames, livestock fencing (Z275 coating)
  3. ‌Hydraulics‌:
    • ‌ASTM A53 GrB (10–50mm)‌: Low-pressure water/gas lines (hydrostatic tested @15–30MPa)

‌Why Our Rods?‌

  • ‌Bendability‌: 180° cold bend without cracking (per GB/T 244)
  • ‌Corrosion Resistance‌: Salt spray resistance >600h (ISO 9227)

‌Manufacturing & Quality Control‌

  1. ‌Hot Rolling‌: Billets heated to 1,250°C, rolled via 12-stand continuous mill.
  2. ‌Cooling‌: Stelmor process for uniform ferrite-pearlite microstructure.
  3. ‌Surface Treatment‌:
    • ‌Galvanizing‌: Immersion in 450°C zinc bath (50–80µm layer)
    • ‌PVC Coating‌: Electrostatic spray (200–400µm thickness)
  4. ‌Testing‌:
    • ‌Ultrasonic Inspection‌: ASTM E213 compliant
    • ‌Hardness Test‌: 71–78 HRB (Rockwell B scale)

‌Competitive Advantages‌

‌Parameter‌ ‌Our Wire Rods‌ ‌Industry Average‌
‌Wall Tolerance‌ ±5% ±8%
‌Lead Time‌ 10–20 days 30–45 days
‌MOQ‌ 1 ton 5 tons

‌Certifications‌:

  • ‌ISO 9001‌: Quality management
  • ‌CE Marking‌: EU compliance for construction
  • ‌MTRs‌: Traceable chemical/physical properties
