CE Certified Aluminium Stack Doors Manufacturer & Factory

Under EN 14351-1:2006+A2:2016 (External pedestrian doorsets), we provide a comprehensive Notified Body Test Report from accredited European testing facilities (such as IFT Rosenheim or equivalent recognized institutions). This includes quantitative classification certificates for Air Permeability (EN 12207: Class 4), Watertightness under static and dynamic pressure (EN 12208: Class 9A or E750/E900), Resistance to Wind Load (EN 12210: Class C5/B5), and Thermal Transmittance Calculation Reports ($U_w$ according to EN ISO 10077-1 and EN ISO 10077-2). Additionally, every shipment carries the factory Declaration of Conformity and CE physical label markings detailing batch numbers and factory production control audits.

While bi-fold doors fold like an accordion perpendicular to the track (projecting panels outward or inward into usable living space), stacking doors slide parallel across independent parallel tracks, nesting panels neatly behind an end pocket or stationary fixed glass leaf. Structurally, stacking doors rely on bottom-rolling tandem bogies resting directly on the foundation rather than hanging their entire cantilevered dead-weight from the overhead building lintel. This structural difference allows individual panels on stacking doors to be fabricated significantly wider (up to 2500mm wide and 4000mm high) and accommodate triple-glazed, hurricane-resistant IGUs exceeding 400kg per leaf without causing header sag or operating bind.

For projects situated within 3 miles (5 km) of marine coastlines, standard architectural powder coatings will fail prematurely due to salt-spray penetration at sharp extruded corners. We mandate Qualicoat Class 2 "Seaside" certified powder coating or Fluorocarbon PVDF (Kynar 500 / 70% resin) multi-coat electrostatic spray systems complying with AAMA 2605. Our pre-treatment protocol replaces cheap iron phosphate washes with multi-stage zirconium or chrome-free passivations followed by rigorous acid etching to eliminate free iron particles. This ensures our profiles pass over 4,000 hours of continuous acetic acid salt spray (AASS) testing with zero blistering, flaking, or filiform creep.

Yes. True barrier-free ADA and European accessibility compliance requires a maximum vertical step-over of 12.5mm to 15mm. To achieve this without water ingress during heavy cloudbursts, we utilize our patented concealed sub-floor continuous linear drain box. The aluminium track sits flush with indoor hardwood and exterior tiles; driven rainwater bypasses the track gaps through engineered channel slots into an integrated stainless steel catchment tray connected directly to the building's 50mm perimeter storm drain pipes. This system maintains a watertight threshold rating of up to 450 Pa while providing a flush, trip-free architectural aesthetic.

Because we operate an expansive 180,000 m² facility with in-house extrusion inventory, our production lead time for standard powder-coated models is 20 to 25 calendar days following CAD shop drawing approval. Custom anodized, PVDF, or specialized curved glass projects require 30 to 35 days. We support projects of all scales: our MOQ is flexible (1 full villa package or multi-unit commercial tenders). Shipments can be booked on FOB (Foshan, Guangzhou, or Shenzhen ports) or CIF / DDU / DDP terms to major global shipping hubs across North America, Europe, Australia, and the Middle East.

Depending on jobsite hoisting equipment and shipping container dimensions, we offer two delivery configurations: Fully Pre-Glazed and Assembled Units (ideal for low-rise projects where units can be directly craned into structural rough openings) or Knocked-Down (KD) Precision Kit Assemblies. In KD mode, outer multi-track jambs and headers are pre-milled and corner-cleated for rapid jobsite assembly, while door leaves come fully factory-glazed or dry-gasket glazed. Every component is laser-etched with matching numbering corresponding to our step-by-step 3D structural installation manuals.
