Custom-fabricated aluminium steel-look internal doors engineered for architectural partitions, commercial fit-outs, and luxury residential projects worldwide.
The architectural heritage of Crittall styling—characterized by slim profile grid lines, industrial aesthetics, and maximum daylighting—has undergone a major material shift in modern construction. While hot-rolled steel was historically the standard for framing, modern commercial developments and luxury residential builds increasingly specify extruded T6-6063 high-grade aluminium alloy.
From an engineering perspective, aluminium Crittall-style internal door systems resolve the critical physical drawbacks of traditional steel: high structural mass, vulnerability to edge-rust under ambient humidity, and fabrication limits in complex thermal-break integration.
| Performance Metrics | Extruded Aluminium (Window Wurx Spec) | Traditional Hot-Rolled Mild Steel | Architectural Procurement Advantage |
|---|---|---|---|
| Structural Density | 2.70 g/cm³ | 7.85 g/cm³ | 67% mass reduction; lowers floor load & hardware wear |
| Corrosion Resistance | Inherent passivating oxide layer + PVDF/Anodized | Requires galvanized priming; susceptible to rust | Zero maintenance in wet interior zones (Bathrooms, Spas) |
| Profile Precision | Micron-level CNC extrusion tolerance (±0.15mm) | Thermal distortion during welding process | Seamless mitred corners and ultra-clean glazing joints |
| Thermal Break Integration | Polyamide PA66 GF25 thermal barrier strips | Difficult steel welding bridges thermal break | Eliminates condensation transfer between interior zones |
| Acoustic Performance (STC) | Up to STC 42 (with 10.8mm acoustic PVB glass) | STC 32-35 (standard single glazing profile) | Superior sound attenuation for executive conference rooms |
Established in 1993 in Dali Town, Foshan—China's global capital for architectural aluminium processing—Window Wurx Industry Co., Ltd. operates a 20,000 square meter standardized production base. Powered by 3 automated double-head CNC cutting and machining lines and staffed by over 150 skilled fabrication specialists, our annual export volume maintains a steady 30% year-on-year growth trajectory across North America, Europe, Australia, and the Middle East.
Full compliance with European CE standards (EN 14351-1), Australian AS2047, and American NFRC thermal performance protocols. Complete lab test certificates are available for project submittals.
We produce both True Divided Lites (TDL) and Simulated Divided Lites (SDL) utilizing ultra-slim 15mm-20mm internal profile bars engineered for minimalist sightlines without compromising frame rigidity.
Zero transit damage protocol: EPE foam wrapping, corner guards, plastic stretch wrap, inner honeycomb padding, and fumigation-free solid plywood crating reinforced with container tension strapping.
Advanced electrocoat anodizing and powder coating allow different interior vs exterior colors on the same frame profile, satisfying matching architectural interior schemes.
The market demand for interior glass partitions has evolved beyond basic spatial division. Modern commercial developers, hotel chains, and luxury custom builders are driving structural shifts in how Crittall-style doors are specified:
Architectural specifications are moving away from traditional 45mm frame profiles toward ultra-narrow sightline systems. Window Wurx's proprietary AS2047 Minimalist Series reduces visible vertical mullion faces to just 15mm, increasing daylight transmission by 14.2% over conventional framed glass partitions while maintaining structural wind load resistance for high-rise interior applications.
With the rise of hybrid workplace designs and multi-functional residential spaces, "flexible acoustic zoning" has become a primary procurement metric. Utilizing double-glazed laminated glass build-ups (e.g., 5mm Clear Tempered + 0.76mm PVB + 5mm Clear Tempered) mounted within perimeter-sealed aluminium Crittall frames enables noise suppression up to 38–42 dB, allowing private phone calls or executive meetings to occur alongside open workspace environments.
Procurement for luxury hospitality and corporate boardrooms is increasingly integrating Switchable Polymer Dispersed Liquid Crystal (PDLC) glass within aluminium Crittall grid frames. With a single button press or smart building control trigger, the glass transitions from 89% optical transparency to complete privacy opacity in under 100 milliseconds.
Our window and door systems are CE certified under European standard EN 14351-1, tested to Australian Standard AS2047 for structural deflection and water ingress, and compliant with North American NFRC thermal standards. Complete physical lab test reports, glass tempered safety compliance (EN 12150 / ANSI Z97.1), and alloy mill certificates are supplied with every export order batch.
Yes. Every door system is fabricated 100% to project shop drawings. You can specify overall frame dimensions, custom grid panel layouts (e.g., 2x3, 2x5, asymmetrical modern grid lines), frame wall thickness (1.4mm to 2.5mm), glass spec (reeded/fluted, frosted, clear, acoustic laminated), hardware finishes, and frame surface finishes including custom RAL color matching.
We deploy a rigorously engineered 5-layer export packaging protocol. Each individual door leaf and outer frame is wrapped in multi-layer EPE foam and scratch-resistant film, padded with corner guards, packed inside high-density honeycomb cardboard, and encased inside fumigation-free solid plywood crates. Container loading incorporates inflatable air bags and steel strapping to eliminate transit vibration impact.
True Divided Lite (TDL) utilizes individual glass panes fitted into structural aluminium muntin bars, ideal for heavy-duty industrial doors. Simulated Divided Lite (SDL) uses a large single sheet of tempered glass with precision CNC-machined aluminium grid bars adhered to both interior and exterior glass faces. SDL provides superior thermal sealant integrity, easier cleaning, and lighter frame mass while delivering identical visual aesthetics.
Yes. We offer an established Global Dealer & OEM Partnership program. We support trade partners with direct wholesale factory pricing, custom CAD shop drawings within 24 hours, sample profile kits, project bid submittal assistance, and dedicated logistics management from our Foshan export terminal directly to your job site or warehouse.
Standard production lead time is 25 to 35 calendar days following formal CAD shop drawing sign-off and deposit receipt. Expedited 18-day manufacturing schedules are available for time-sensitive commercial project contracts upon request.
