As a specialized manufacturer with ISO-certified facilities in Changsha, Hunan Yige Special Steel leverages 9+ years of metallurgical expertise to deliver Precision Welded Oval Steel Pipes engineered for demanding architectural projects. Our 5,000-10,000 sqm factory enables strict control over dimensional accuracy and weld integrity – critical for structural aesthetics and safety in modern construction.
Core Technical Advantages:
- Aerodynamic & Aesthetic Design: Smooth oval profile reduces wind load resistance in facades and offers sleek visual lines for railings, canopies, and artistic installations.
- Zero-Defect Welding: High-frequency induction welding ensures seamless, uniform joints with <0.2mm tolerance, eliminating weak points.
- Material Consistency: Sourced from certified mills, our carbon steel (Q195-Q345/SS400) maintains uniform yield strength (≥235MPa) and elongation (≥23%).
- Corrosion Resilience: Optional hot-dip galvanizing (140-200g/m²) or powder coating (60-80μm) per ASTM A123/A153 standards.
Key Specifications:
| Dimension (Major Axis x Minor Axis) | Wall Thickness | Tolerance |
|---|---|---|
| 20mm x 10mm to 300mm x 150mm | 0.5mm - 6.0mm | ±0.3mm (OD), ±10% (WT) |
| Custom oval ratios (1.5:1 to 3:1) | Cold-rolled/Hot-rolled | ASTM A554 compliant |
