Explore our precision-engineered aluminum structural solutions certified for global commercial, residential, and industrial applications.
In modern structural architecture, the boundary between indoor luxury and outdoor environment has blurred. The global demand for ultra-wide, uninterrupted panoramic openings has accelerated the adoption of Aluminum Stacking Doors over legacy bi-fold and conventional dual-track sliding assemblies. Architectural stacking doors utilize a multi-track head and sill mechanism, allowing multiple sashes to slide smoothly along parallel tracks and stack neatly behind a single fixed panel or pocket wall.
Unlike traditional bi-fold doors, which require significant projection space inside or outside the living envelope and create vertical visual breaks via multiple hinge profiles, aluminum stacking systems deliver unrivaled glass-to-frame ratios, high wind-load resistance (DP rating), and frictionless horizontal glide kinetics. As energy efficiency codes (such as ASHRAE 90.1, Title 24, and Eurocode EN 14351-1) become increasingly strict globally, aluminum stacking door engineering has shifted from standard extrusions to complex multi-chambered thermal break profiles integrated with structural polyamide (PA66 GF25) barriers.
Engineered with T6-grade 6063 extrusions, stacking doors handle massive panel dimensions (up to 3.5m in height and 300kg per sash) without sag or track binding, outperforming standard sliding profiles.
Allows 75% to 85% clear opening width. Panels seamlessly stack into engineered wall cavities, completely removing physical barriers between indoor spaces and external patios.
Multi-stage EPDM gasket weather-stripping combined with continuous bottom drainage tracks provides superior protection against water ingress during severe cyclonic storms.
Established in 2015, Guangzhou Cresta Door & Window Co., Ltd. operates a state-of-the-art 18,000-square-meter manufacturing facility. Backed by 11 years of deep industry expertise and 7 years of international trade operations, Cresta has positioned itself as China’s premier engineering exporter of custom architectural window and door solutions, achieving an annual export turnover of $22 million across Southeast Asia, the Middle East, and Oceania.
We primarily serve high-end custom home builders, commercial renovation contractors, structural engineering firms, and regional building material wholesalers. To guarantee top-tier craftsmanship, our quality assurance protocol involves 30 QC inspectors enforcing strict ISO-certified optical surface inspections, structural shear resistance testing, and pressure-chamber weatherproofing seal evaluations. Supported by 550 upstream raw material suppliers and an active R&D division of 35 specialized engineers, Cresta successfully launched 38 new patented product series over the past calendar year alone.
Our 18,000 m² workshop integrates German CNC machining centers, automated face milling units, structural glass bonding cells, and precise frame debugging rigs to maintain tight tolerances down to ±0.5mm.
To withstand extreme environmental forces—ranging from coastal typhoon winds to desert thermal spikes—Guangzhou Cresta constructs aluminum stacking doors utilizing rigorous aerospace-grade alloy parameters, multi-barrier thermal breaks, and structural glass glazing matrix.
We use primary (non-recycled) 6063 aluminum alloy artificially aged to a T6 temper. This delivers a tensile strength exceeding 205 MPa and a yield strength over 170 MPa. Wall thicknesses across structural loading zones range from 2.0mm to 3.0mm, allowing maximum panel stabilization and zero frame flex under extreme pressure.
Our thermal break stacking doors incorporate 24mm to 34mm Technoform polyamide PA66 reinforced with 25% fiberglass. This thermal barrier decouples the exterior aluminum skin from the interior profile, lowering frame U-values down to Uf ≤ 1.6 W/m²K and eliminating interior moisture condensation in extreme cold conditions.
Glazing configurations include double-pane (6mm + 12Ar + 6mm) and triple-pane toughened Low-E glass units filled with 90%+ Argon gas. Warm-edge composite spacers minimize thermal bridging around perimeter seals, providing total window U-values as low as Uw 1.2 W/m²K and Sound Transmission Class ratings up to STC 42 dB.
Each stacking panel glides on heavy-duty CNC-machined SUS304 stainless steel quad-bogie rollers rated for over 300,000 continuous operation cycles. Precision sealed bearings ensure effortless push/pull force under 15N even when operating massive 300kg double-glazed sashes.
