Explore our core industrial and architectural aluminum profile extrusions manufactured for high-performance global applications.
Qianyu Aluminum Industry boasts over 19 years of professional experience in the production and precision extrusion manufacturing of advanced aluminum profiles and structural solutions. As a premier global manufacturer, we operate high-tonnage extrusion presses, automated surface finishing lines, and advanced CNC machining centers dedicated to producing world-class aluminium sliding door profiles, architectural curtain walls, residential fences, and heavy industrial components.
Our engineering team combines deep metallurgy insights with computational design (CAD/CAM/FEA) to manufacture 6000-series alloy systems that meet strict international structural codes. By focusing on thermal insulation, structural rigidity, smooth sliding mechanisms, and extreme environmental durability, we serve architects, master developers, system fabricators, and commercial distributors across more than 50 countries.
Addressing the evolving engineering demands of modern high-rise buildings, commercial storefronts, and eco-friendly urban infrastructure.
Modern architectural trends demand ultra-large sliding glass panels spanning over 3.5 meters in height. Our extruded 6063-T6 and 6005A-T6 profiles feature optimized wall thickness distribution, delivering high moment of inertia and wind resistance capable of withstanding pressures up to 3000 Pa (equivalent to Category 5 hurricanes).
Incorporating multi-cavity PA66GF25 polyamide thermal break strips, our wholesale sliding door extrusions effectively isolate indoor thermal energy from outdoor weather extremes. Achieving overall frame U-values as low as 1.4 W/m²K, our systems assist green building projects in achieving LEED and BREEAM certifications.
Engineered for hostile coastal, industrial, and high-UV environments, our surface finishing technologies—including Qualicoat Class 2 powder coating, PVDF fluorocarbon spraying, and Qualanod hard-coat anodizing—prevent oxidation, pitting, and color degradation over a 25-year lifecycle.
The manufacturing process of high-precision wholesale aluminium sliding door profiles relies on strict mechanical tolerances, thermal dynamics, and chemical alloy composition. Below is the technical breakdown of our engineering standard operational metrics:
| Performance Parameter | Standard Specification | Engineering Benefit |
|---|---|---|
| Alloy Composition | AlMgSi0.5 (6063-T5 / T6) & AlMg1SiCu (6061-T6) | Superior structural strength, lightweight profile, exceptional surface anodizing clarity. |
| Wall Thickness Range | 1.4 mm to 3.0 mm (Heavy-duty commercial profiles up to 4.5 mm) | Optimized structural loading without excessive mass; prevents frame deflection. |
| Extrusion Tolerance | DIN EN 12020-2 / BS EN 755-9 Precision Standard | Ensures seamless gasket seating, zero air leakage, and precise track fitting. |
| Thermal Insulation Strip | 24 mm - 34 mm PA66GF25 (25% Glass-Fiber Reinforced Nylon) | Drastically lowers thermal bridge effect; high shear strength under thermal strain. |
| Surface Coating Thickness | Powder Coating: 60-80 μm | Anodizing: 15-25 μm | PVDF: >40 μm | Resists atmospheric corrosion, acid rain, salt spray testing up to 3,000 hours. |
| Glazing Compatibility | Single (6-12mm), Double (24-32mm), Triple Glazing (40-48mm) | Provides sound insulation up to 42 dB (Rw) and enhanced security barrier. |
| Water Tightness & Air Permeability | Class E1050 (Water) / Class 4 (Air - EN 12207) | Prevents water ingress during heavy storms; reduces HVAC energy loss. |
To support OEM/ODM B2B buyers, Qianyu Aluminum maintains an in-house tool and die design facility utilizing CAD/CAM modeling.
