Cold Drawn Carbon Steel Hexagonal Tube 4-200mm OD with ±0.10-1.0mm Tolerance for Structural Applications
Zhengde special-shaped steel pipes represent a comprehensive category of seamless steel pipes featuring non-circular cross-sections. These precision-engineered tubes are manufactured through cold drawing processes to achieve superior dimensional accuracy and mechanical properties.
Special-shaped seamless steel pipes are extensively utilized in structural components, tool manufacturing, and mechanical parts. Compared to conventional round pipes, these profiles offer significantly higher moment of inertia and section modulus, providing enhanced bending and torsion resistance while reducing structural weight and material consumption.
- Equal wall thickness special-shaped seamless steel pipes
- Unequal wall thickness special-shaped seamless steel pipes
- Oval, triangular, and hexagonal profiles
- Rhombus, octagonal, and semi-circular designs
- Five-petal plum blossom and double convex/concave shapes
- Melon-shaped, conical, and corrugated configurations
Available thickness: 0.5mm to 2.0mm (±10% tolerance, minimum ±0.12mm)
