High-precision aluminum extruded tubes, micro-port capillaries, and structural profiles engineered for global industrial deployment.
Qianyu Aluminum Industry boasts 19 years of dedicated experience in metallurgical processing, precision extrusion, and custom fabrication of high-grade aluminum products. As a premier global aluminum tube manufacturer and extrusion factory, we integrate advanced engineering, automated extrusion presses, and state-of-the-art CNC machining components to deliver solutions tailored for aerospace, automotive, HVAC, electrical, architectural, and structural applications.
Our multidisciplinary team comprises passionate metallurgical engineers, industrial designers, and global procurement specialists. Driven by strict quality assurance protocols, we ensure every extruded aluminum round tube, square tube, capillary pipe, and structural profile satisfies rigorous international benchmarks including ISO 9001, IATF 16949, and CE certifications.
Selecting the optimal aluminum alloy and temper is critical for balancing yield strength, weldability, corrosion resistance, and thermal efficiency.

| 5052 Aluminum | H32 / H34 | 210 - 260 | 138 - 150 | Marine fittings, coastal aluminum fencing, outdoor structural panels, anti-corrosive tiles. |
| 7075 Aluminum | T6 / T6511 | 530 - 570 | 130 - 140 | Aerospace components, high-stress defense equipment, precision CNC components. |
Global procurement teams must evaluate beyond initial purchasing price. By selecting lightweight aluminum extruded tubes (which weigh 60% less than steel), enterprises drastically lower freight costs, minimize structural deadload, and eliminate ongoing anti-rust maintenance overhead.
Our cold-drawing and direct extrusion lines achieve strict outer diameter (OD) and inner diameter (ID) tolerances up to ±0.02 mm. This accuracy guarantees seamless integration into high-precision CNC assemblies, robotic sliding modules, and micro-port heat exchangers.
Backed by an inventory of over 5,000 tons of raw aluminum ingots and thousands of active extrusion dies, Qianyu Aluminum provides rapid prototyping (7 days) and reliable volume production cycles, safeguarding global supply chains against supply shocks.
Exploring how advanced aluminum tubing technologies drive performance across major industrial sectors worldwide.
As electric vehicles demand higher battery range and thermal control, our aluminum capillary tubes and multi-port extruded (MPE) profiles serve as core components in battery cooling plates, HVAC condensers, and refrigerant lines. Lightweight 6000-series alloy structural tubes also replace conventional heavy steel frames, reducing vehicular mass while maintaining high crash energy absorption (tensile strength 200–350 MPa).
Utilizing high thermal conductivity alloys (such as 3003 and 6063), Qianyu Aluminum manufactures high-efficiency aluminum alloy radiators and heat sink tubing. Engineered with inner-grooved micro-channels, these tubes optimize heat transfer rates for industrial refrigeration units, data center cooling grids, and solar thermal collectors.
Modern architecture relies heavily on extruded aluminum profiles for structural aesthetics and environmental resilience. From wood-grain aluminum round tubes for natural outdoor visual effects to heavy-duty curtain wall framing, aluminum siding, wave ceiling panels, and anti-static raised flooring, our architectural products offer unmatched UV resistance and anti-corrosion life spans surpassing 20 years.
High-precision linear sliding modules and automated machinery frames require rigid, lightweight aluminum extrusions. Our CNC-machined 6061-T6 profiles feature high straightness, minimal deflection, and hard-coat anodized surfaces for low-friction linear guide operations in smart factory environments.
Enhancing surface hardness, corrosion endurance, wear resistance, and visual elegance through automated finishing lines.
Forms an electrochemical oxide layer (thickness 25–50+ microns) with surface hardness reaching up to 400–500 HV. Essential for high-wear mechanical parts, pneumatic cylinders, and military-spec equipment.
Formulated with premium Kynar 500 resin, providing extreme weatherability, chemical resistance, and salt spray endurance exceeding 3,000 hours (ASTM B117 standard). Ideal for coastal and high-rise curtain walls.
Available in over 200 RAL color choices. Delivers an eco-friendly (VOC-free), uniform, UV-resistant coating ideal for outdoor garden fences, balcony railings, louvers, and architectural pergolas.
Combines the organic aesthetic of natural timber with the structural strength and non-flammability of aluminum alloy. Zero warping, termite-proof, and completely maintenance-free.
Demonstrating real-world performance, engineering integration, and structural longevity.
Aluminum alloy raised flooring is designed for demanding environments such as server cleanrooms, semiconductor fabs, and control centers where high load capacity, low weight, and anti-static properties are critical. Manufactured via high-pressure die casting from pure aluminum ingots, these panels yield exceptional dimensional stability and uniform structural density.
Constructed from structural 6000-series aluminum alloys, our custom outdoor pergolas combine robust yield strength (tensile strength up to 350 MPa) with a lightweight design that reduces foundation installation costs. Capable of supporting unsupported clear spans up to 12 meters, these systems are weather-resistant and ideal for commercial parks, rooftop dining, and high-end residential patios.
Architectural aluminum profiles are replacing heavy steel and rot-prone wood in modern building envelopes. Our modern aluminum fencing, balcony handrails, and sun-louver systems provide an elegant security barrier with zero rust concerns. Designed for easy installation, these profile systems comply with high wind-load ratings and modern green building codes.
