Our Triangular, Hexagonal, Octagonal, Square & Rectangular Special-Shaped Sections excel in versatile performance. Crafted from premium materials, they offer robust structural strength, with unique shapes optimizing load distribution and fit for specific applications.
Hexagonal/octagonal designs enhance grip in machinery, while square/rectangular sections provide stable framing in construction. Triangular variants suit space-saving structural needs. Their precision dimensions ensure seamless integration, reducing assembly time. Resistant to wear and adaptable to coatings, they perform reliably in automotive, construction, and industrial settings, blending form with functional efficiency.
The external hexagonal profile creates multiple uniform contact surfaces with mating parts (e.g., hexagonal holes in gears, pulleys, or couplings). This design:
Eliminates rotational slip between the shaft and connected components, ensuring 100% torque transfer even under heavy loads (e.g., in industrial mixer drives or conveyor systems).
Distributes torque evenly across six flat sides, reducing stress concentration (a common issue with round shafts relying on single keyways). It can handle 15–30% higher torque than round shafts of the same material and cross-sectional area.
2. High Mechanical Strength & Stability
Material-Driven Durability: Typically made from high-performance steels such as 45# medium carbon steel, 40Cr alloy steel, or 304 stainless steel. For example:
Quenched-tempered 45# Hex Shaft Steel offers a minimum yield strength of 355MPa and tensile strength of 600MPa, resisting bending and torsion in heavy-duty machinery.
40Cr alloy steel variants provide even higher strength (yield strength ≥785MPa) and impact resistance, suitable for automotive steering shafts or construction equipment.
Structural Rigidity: The hexagonal shape enhances anti-bending and anti-torsion rigidity, maintaining dimensional stability under long-term loads (e.g., as drive shafts in gearboxes).
3. Precision Dimensional Accuracy
Manufactured via high-precision processes like cold drawing and grinding:
Dimensional tolerance for key parameters (e.g., side length, flatness) is controlled within ±0.05mm, ensuring seamless assembly with mating parts (no need for time-consuming on-site adjustments).
Surface finish reaches Ra ≤0.8μm after grinding, reducing friction between the shaft and bearings/couplings, and minimizing wear during operation.
4. Easy Installation & Maintenance
Tool-Friendly Design: The hexagonal sides allow easy gripping with standard tools (e.g., wrenches), simplifying installation and disassembly—no need for specialized fixtures.
No Extra Locking Components: Unlike round shafts (which require keys, set screws, or pins to prevent rotation), the hexagonal profile locks directly with mating parts, reducing assembly steps and eliminating the risk of loose fasteners over time.
5. Versatile Material Options
Materials are selected based on application requirements:
Carbon Steel (45#, A36): Cost-effective for general industrial use (e.g., machinery frames, low-load shafts).
coated steel pipe has excellent corrosion resistance and relatively small friction resistance. Epoxy resin coated plastic steel pipe is suitable for water supply and drainage, sea water, warm water, oil, gas and other media transportation, polyvinyl chloride coated plastic steel pipe is suitable for drainage, sea water, oil, gas and other media transportation.

Special-shaped steel pipe
Shaped seamless steel pipe is widely used
Used for various structural parts, tools and mechanical parts. Compared with the circular tube, the shaped tube generally has a larger moment of inertia and cross-section modulus, and has a larger
Anti-bending, anti-torsion, can greatly reduce the weight of the structure, save steel.
