Discover our primary high-precision fabrications designed for heavy-duty architectural, industrial, safety, and commercial hardware applications.
In modern engineering, the demand for materials that balance high structural integrity with minimal weight is at an all-time high. ODM Aluminum Hollow Bars represent a critical breakthrough in global industrial metallurgy, replacing heavy solid metal bars and expensive, welded structural tubes. By utilizing seamless extrusion techniques, these hollow profiles offer optimized moment of inertia, exceptional torsional resistance, and maximum fluid passage capability.
Industrial demand has shifted drastically toward custom, original design manufacturing (ODM). Procurement agents and design engineers from North America, the European Union, and Asia-Pacific require precision hollow profiles tailored to mechanical systems. Whether it is a hydraulic piston housing, a high-speed rotating axis, or structural rigging elements for aerospace and safety applications, choosing the right aluminum alloy determines structural performance and overall manufacturing yield.
Hollow geometries reduce deadweight by up to 50% compared to solid equivalents, enabling faster machinery acceleration, lower energy usage, and simplified structural support requirements.
Pre-formed inner bores dramatically reduce boring, drilling, and chip removal times. This leads to minimized cutting tool wear and lower machining labor rates per piece.
Aluminum's infinite recyclability combined with lightweight operations aligns with strict international ecological goals such as EU GRS (Global Recycled Standard) protocols.
Choosing the right chemical composition is crucial. Our in-house smelting operations allow precise control over trace elements to achieve desired material properties.
| Alloy Series | Common Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Primary Industrial Applications | Anodizing Capability |
|---|---|---|---|---|---|
| 6063 | T5 / T6 | 186 - 240 | 145 - 214 | Architectural systems, window & door tracks, structural frames, LED brackets | Excellent (Mirror, Satin, Matte) |
| 6061 | T6 | 290 - 310 | 240 - 276 | Heavy-duty machinery, hydraulic manifolds, auto parts, structural connectors | Very Good (Industrial protection) |
| 7075 | T6 | 510 - 572 | 434 - 503 | Aerospace linkages, professional climbing gear, high-stress load junctions | Good (Best for hard-anodizing) |
| 3XXX / 5XXX | H32 / H34 | 170 - 260 | 90 - 200 | Marine fittings, heat exchangers, fluid piping systems | Fair (Corrosion resistant) |
For standard structures, port-hole die extrusion (welded hollows) offers cost-efficiency. However, for critical pressure applications like pneumatic cylinders and components that undergo intensive internal machining, mandrel-extruded seamless hollow bars are required. This ensures zero weld-line defects, providing uniform structural strength across the entire cross-section.

Procuring custom aluminum hollow profiles at scale requires understanding key price drivers. Unlike off-the-shelf pipe fittings, the costing model for ODM aluminum hollow bars is divided into distinct components:
This follows global commodity indexes (LME/SHFE). In-house recycling loop operations minimize processing waste, protecting buyers from extreme market price surges.
Custom ODM profiles require dedicated steel dies. We offer flexible amortization terms: for large contracts, tooling costs are fully refunded once minimum quantities are achieved.
Our machining shop handles precision boring, turning, cross-hole milling, and high-frequency welding. Eliminating logistics between different factories saves up to 15-20% on costs.
| Outer Diameter Range | Wall Thickness Range | Alloy Grade | Estimated Cost Range (USD/Ton) | Minimum Order Qty (MOQ) |
|---|---|---|---|---|
| 20mm - 80mm | 2.0mm - 10.0mm | 6063-T5 | $3,100 - $3,600 | 1.0 - 2.0 Metric Tons |

Common questions answered by our engineering and quality departments.
Standard pipes are intended for fluid conveyance and focus on pressure ratings, whereas aluminum hollow bars are engineered as structural feedstocks designed for precision machining. Hollow bars offer thicker walls, tighter dimensional tolerances, and controlled grain orientation to prevent deformation during high-speed CNC turning and boring.
Anodizing highlights structural and metallurgical flaws. If scrap metal inputs are contaminated with iron, silicon, or zinc, the anodized surface will show streaks and discolorations. By melting and refining our billets in-house, we eliminate external contaminants, ensuring uniform oxide growth during clear, bronze, or black anodizing.
We hold ISO14001 environmental management system certifications, alongside Global Recycled Standard (GRS) and RCV credentials. This ensures our aluminum profiles comply with the strict environmental requirements of the European Union's REACH and RoHS regulations, validating our supply chain transparency.
Our precision workshop offers one-stop processing, including high-speed precision cutting, multi-axis CNC milling, drilling, thread tapping, slotting, precision boring, complex bending, structural welding, and multi-component assembly. This reduces overall lead times.
From structural rails to specialized hardware and safety equipment, our custom products are engineered to perform under demanding conditions.
