Over 19 Years of Excellence in Advanced Aluminum Extrusion, Architectural Solutions, and High-Performance Alloys
Qianyu Aluminum Industry boasts 19 years of professional experience in the design, metallurgical engineering, and manufacturing of high-performance aluminum materials. As a premier global exporter and factory, Qianyu Aluminum is dedicated to supplying high-grade structural aluminum hollow sections, architectural curtain wall profiles, custom residential fences, gazebos, and industrial components. Our enterprise is powered by an elite team of metallurgical engineers, CAD/CAM designers, and international supply chain experts equipped with deep domain authority, ensuring every extrusion conforms to rigorous global benchmarks.
Our structural hollow profiles undergo multi-stage ultrasonic testing, spectrographic alloy validation, and strict dimensional audits to ensure uncompromised load safety and structural longevity.
With over 50,000 active mold dies and rapid 48-hour tooling development, we convert complex architectural drawings into precision-extruded profiles matching exact project parameters.
Leveraging a raw material buffer stock of 5,000 metric tons and strategic port connectivity, Qianyu guarantees predictable lead times and reliable global shipping logistics.
Aluminium hollow sections—encompassing square (SHS), rectangular (RHS), circular (CHS), and intricate multi-chamber structural profiles—represent a foundational material category in modern engineering. In contrast to solid profiles or cold-formed steel sections, extruded aluminium hollow profiles deliver an exceptional strength-to-weight ratio, remarkable torsional rigidity, and innate atmospheric corrosion resistance.
Across North America, Europe, the Middle East, and Asia-Pacific, the demand for aluminium hollow sections is accelerating rapidly due to global decarbonization mandates, the rise of modular pre-fabricated construction, lightweight vehicle body engineering, and large-scale solar PV mounting infrastructures. By substituting traditional structural steel with 6xxx-series structural aluminium hollow profiles, project engineers reduce overall deadweight by up to 60% while eliminating the need for periodic maintenance against iron rust.
Selecting the appropriate aluminium alloy temper is critical for balancing tensile strength, ductility, weldability, and surface finish aesthetics. The table below outlines the mechanical and chemical parameters of prime structural alloys manufactured in our facilities:
| Alloy & Temper | Yield Strength (MPa) | Tensile Strength (MPa) | Elongation (%) | Primary Application Scenarios |
|---|---|---|---|---|
| 6063-T5 / T6 | 170 - 210 | 215 - 245 | 8 - 12 | Architectural framing, window/door curtain walls, garden fencing, pergolas |
| 6061-T6 | 240 - 276 | 290 - 310 | 9 - 10 | Heavy structural frameworks, marine decks, automotive chassis, helipad beams |
| 6005A-T6 | 215 - 250 | 260 - 290 | 8 - 10 | Railway car structures, high-stress structural hollow tubing, busbars |
| 6082-T6 | 255 - 280 | 300 - 340 | 8 - 10 | High-load structural bridges, offshore platforms, heavy machinery frames |
China's extrusion sector represents the world's most vertically integrated aluminium manufacturing ecosystem. Our factory leverages localized raw material refining (primary bauxite to high-purity aluminium billets), automated continuous extrusion presses ranging from 800-ton to 10,000-ton capacity, and inline artificial aging ovens.
This concentrated industrial ecosystem allows Qianyu Aluminum to achieve unmatched cost-efficiencies and delivery speed. While western regional manufacturers often require 8 to 12 weeks for custom die tooling and sample validation, our integrated R&D center completes die design, CNC wire-cutting, extrusion testing, and sample dispatch within 48 to 72 hours.
Exploring structural hollow sections across residential, commercial, and engineering sectors.
Our vision is to become a global leader in the field of structural aluminium hollow sections, premium aluminium fences, and decorative building materials. Through active cooperation with numerous engineering enterprises worldwide, our products have gained widespread international acclaim. By integrating CAD/CNC customization, high-speed automated extrusion, and eco-friendly finishing, we empower projects across 60+ countries.
Crafted from high-grade 6xxx series structural aluminium alloys, our custom gazebos and pergolas offer a tensile strength of 200–350 MPa while remaining 60% lighter than structural steel frameworks. Designed for rooftop gardens, luxury poolside installations, and public parks, they reduce foundational load stress while spanning clear lengths up to 12 meters without intermediate column support.
Our residential and commercial aluminium fencing systems combine robust security barriers with refined aesthetics. Utilizing precision square and rectangular hollow profiles with wall thicknesses from 1.5 mm to 3.0 mm, these perimeter systems are resistant to coastal salt spray, rust, and UV discoloration for over 15 years.
Designed for mission-critical data centers, cleanrooms, and offshore marine docks, our aluminium alloy raised flooring panels utilize high-pressure die-casting from pure ingots. Capable of supporting concentrated loads exceeding 1,500 kg/m², these panels are finished with electrostatic epoxy powder coating, nickel-chromium plating, or HPL/PVC surface veneers for optimal anti-static performance.
From grooved square tubes and curved dynamic profiles to heat-sink radiators and wood-grain thermal transfer ceiling tubes, our decorative extrusion series meets diverse aesthetic mandates. Thermal break profiles featuring PA66-GF25 structural polyamide strips effectively isolate thermal bridging in high-rise window and curtain wall applications.
Engineered coatings for superior corrosion resistance and long-lasting aesthetic appeal.

Our structural hollow sections are extruded in strict compliance with EN 755-9 and EN 12020-2 precision standards. Standard wall thickness tolerance is within ±0.15 mm, and twist/straightness deviation is held under 1.5 mm per meter. Tighter custom tolerances can be achieved via secondary precision drawing processes.
Aluminium 6061-T6 or 6082-T6 hollow sections offer approximately one-third the weight of structural steel while providing yield strength comparable to mild steel (240–270 MPa). Aluminium forms a self-passivating oxide layer that eliminates structural rusting, making it vastly superior in coastal, marine, and chemical exposure environments.
For standard catalog dies, our minimum order quantity starts at 500 kg per profile section. For custom extrusion profiles requiring new mold dies, sample lead time is 7 to 10 days post CAD approval, with full mass-production batch delivery completed in 15 to 20 business days.
For marine or coastal installations within 5 miles of salt ocean breeze, we strongly recommend Fluorocarbon (PVDF) 3-coat spraying or Hard Coat Anodizing (>25 microns). PVDF coatings pass 3,000+ hours of continuous salt-spray testing without blistering or color shifting.
