Explore our primary structural and decorative aluminium extrusion catalog engineered to precise international specifications.
Analysis of alloy thermodynamics, structural optimization, and supply chain dynamics across modern architectural and industrial sectors.
The global industrial economy is experiencing a massive structural transition toward lightweight, highly recyclable, and high-strength structural components. At the center of this shift is the custom aluminium item profile. Utilizing primary 6xxx and 7xxx series aluminum alloys—most notably 6063-T5/T6 for architectural aesthetics and 6061-T6 / 6082-T6 for heavy structural loads—modern extrusion engineering allows manufacturers to achieve unprecedented strength-to-weight ratios.
As a leading Custom Aluminium Item Profile Supplier & Exporter, Qianyu Aluminum incorporates computerized billet heating, nitrogen-shielded die extrusion, and precision water/air quenching systems. This ensures zero internal void formation, superior crystal grain alignment, and mechanical properties that consistently surpass ASTM B221 and EN 755 international standards.
Engineers and international procurement directors rely on precise mechanical parameters to specify custom aluminium profile designs. Below is our standard engineering reference table:
| Alloy & Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Corrosion Rating | Primary Global Applications |
|---|---|---|---|---|---|
| 6063-T5 | ≥ 185 | ≥ 145 | ≥ 8 | Excellent | Architectural Fencing, Window & Door Frames, Louvers |
| 6063-T6 | ≥ 225 | ≥ 180 | ≥ 8 | Excellent | Pergolas, Gazebos, Solar Mounting Rails |
| 6061-T6 | ≥ 290 | ≥ 240 | ≥ 10 | Very Good | CNC Machined Industrial Modules, Helipads, Bridge Decks |
| 6082-T6 | ≥ 310 | ≥ 260 | ≥ 10 | Very Good | Heavy Structural Beams, Marine Floating Pontoons |

Aluminum alloy flooring is designed for high-performance applications where durability, low weight, and corrosion resistance are essential. Utilizing advanced high-pressure die-casting and extrusion technology, these floors are formed from premium aluminum ingots, resulting in a high-density, high-strength product.
Crafted from high-grade aluminum alloys (6xxx series), our pergolas combine strength (tensile strength 200-350 MPa) with a weight 60% lighter than traditional steel structures. Ideal for rooftop gardens, poolside installations, and public parks, they reduce foundational load while supporting clear spans up to 12 meters.
Features fast-track production delivery leveraging our 5,000-ton raw material stock and 50,000+ mold database to shorten procurement lead times by up to 30%.
Architectural decorative aluminum profiles provide lightweight strength, cutting overall building structural mass and foundation costs. Natural oxide surface films offer outstanding resistance to harsh environmental exposure.
Factory & Commercial Uses: Used extensively in curtain walls (framed, unitized, point-supported), linear ceiling panels, composite structural profiles, grilles, sun-louvers, baseboards, canopy frameworks, lighting troughs, partitions, and custom HVAC ducts.
Extruded from high-tensile aluminum alloy, our fencing systems replace traditional steel and timber, offering over 15 years of rust-free outdoor performance with zero maintenance costs.

Clear, expert engineering responses regarding custom aluminium profile design, extrusion tolerances, lead times, and global shipping.
Qianyu Aluminum manufactures custom extrusions in strict adherence to international tolerance standards including EN 755-9, EN 12020-2, and ASTM B221. Standard extrusion tolerances achieve precision within ±0.15mm to ±0.30mm depending on profile geometry. For critical assembly joints, linear modules, and electronic heat sinks, our post-extrusion precision multi-axis CNC machining delivers ultra-tight tolerances up to ±0.02mm.
Alloy selection depends primarily on structural load requirements and decorative finish expectations:
Our rapid tooling program ensures fast market entry. Once CAD engineering drawings are approved, custom extrusion die manufacturing takes 5 to 7 working days. Sample extrusions and initial inspection reports (FAIR) are finalized within 3 days following mold completion. Full mass production lead times typically average 15 to 20 days depending on surface finishing requirements (e.g., anodizing, PVDF spraying, or wood grain sublimation).
For aggressive coastal or industrial atmospheres, we recommend either PVDF (Fluorocarbon) coating (2-coat or 3-coat system) or Class 2/3 Architectural Anodizing (depth ≥ 20 microns). Our PVDF coating systems pass 3,000-hour neutral salt-spray tests without blister formation or color fading, backed by a 15-to-20-year outdoor performance warranty against UV degradation.
Yes. Beyond raw profile extrusion, we provide complete downstream fabrication including CNC precision drilling, counter-boring, slotting, bending, structural welding, and pre-assembly of modular systems (such as pergolas, fences, and solar mounts). Export profiles are individually wrapped with protective shrink film, interleaved with non-abrasive foam, and packed into reinforced steel-framed wooden crates to prevent transit damage during long-distance maritime transport.
Standard minimum order quantity for custom extrusion profiles is typically 500 kg per section. However, for prototype development, initial architectural mock-ups, or specialized high-value industrial profiles, we offer flexible low-MOQ trial production runs supported by our extensive raw billet inventory.
