Top Trusted Aluminum Stacking Doors Supplier & Exporter

Standard sliding doors typically operate on a single or dual-track framework where one operable panel bypasses a fixed panel, restricting the maximum clear aperture to 50%. In contrast, an aluminum stacking door utilizes multiple parallel tracks (typically 3 to 6 tracks) allowing individual panels to slide and gather neatly behind one another or conceal inside a wall cavity (pocket configuration). This yields an unobstructed opening of up to 75% to 85% of the total structural wall width, making it ideal for grand transitions between indoor living spaces and outdoor terraces.

Multi-track systems naturally capture more rain volume across their width. Our engineering approach solves this via a stepped cascade sub-sill extrusion. Each successive outdoor track sits at a calibrated height difference, combined with internal baffle flaps and hidden weep channels. Water is directed down through a concealed front-drain gutter manifold rated up to 700 Pa static water head resistance, preventing moisture backflow into interior floor finishes even under wind-driven storm conditions.

We exclusively extrude primary architectural 6063-T6 or 6060-T66 aluminum profiles with structural wall thicknesses from 2.0mm to 3.0mm, ensuring zero sash warping under high wind-load conditions. For surface finishing, we deploy AkzoNobel or PPG Qualicoat Class 2 certified powder coatings, high-micron anodizing (20μm+), or 3-coat fluorocarbon PVDF systems backed by a 15-to-25-year anti-fading and anti-chalking warranty against aggressive marine and tropical UV environments.

Yes. We design dedicated multi-track extrusions with integrated parallel screen channels. Buyers can specify high-tensile 304 marine-grade stainless steel security mesh (0.8mm wire gauge tested for knife-shear and pry resistance) or retractable pleated insect meshes. These run seamlessly on dedicated tracks parallel to the primary glass leaves without interfering with the multi-point locking system.

Export fenestration demands bulletproof crating. Every glass leaf is wrapped in protective PE film, framed with expanded EPE corner armor, and placed inside ISPM-15 compliant heat-treated plywood crates reinforced with internal steel banding. Tracks and extrusions are packaged in custom-length wooden skeletal frames with desiccants to eliminate condensation stains during extended 30-to-45-day sea voyages.

Every shipment includes precision-labeled assembly hardware, 1:1 scale threshold installation templates, detailed exploded CAD shop drawings, and step-by-step video installation guides. Furthermore, our dedicated English-speaking technical engineering desk provides real-time video conference support to assist your glazing contractors through track leveling, roller height balancing, and multi-point lock alignment.
