Tested against extreme thermal cycles (+55°C ambient), fine Haboob particulate ingress, and coastal saline humidity across Riyadh, Jeddah, Dammam, and NEOM.
Multi-chambered profile with polyamide thermal breaks and specialized acoustic interlayer laminates, delivering Rw 42dB sound reduction against urban traffic.
Treated with Qualicoat Seaside Class II powder coating and SUS316 stainless roller assemblies, engineered specifically for high-salinity Red Sea and Gulf coastlines.
Reinforced structural mullions with quadruple EPDM co-extruded compression gaskets, engineered to withstand intense sandstorms and dynamic pressure up to 4500 Pa.
Equipped with warm-edge spacers, Argon gas filling, and Low-E tempered safety glass, achieving an exceptional thermal transmittance rating under U-value 1.4 W/m²·K.
Engineered for high-end residential compounds and boutique hotels in Diriyah and Al Khobar, featuring flush recessed thresholds for step-free indoor-outdoor living.
Oversized panel capability reaching 4000mm height with specialized multi-point mechanical gear locks, providing uninterrupted panoramic views for restaurants and majlis.
Ultra-narrow 38mm frame sightlines fabricated from 6063-T6 architectural grade aluminum, maximizing daylight transmission while adhering to strict solar heat gain limits.
Dual-function fenestration combining accordion folding sections with modular high-insulation slider panels for coordinated modern residential facades.
Why conventional folding doors fail in the GCC region, and how our specialized thermal barrier engineering overcomes severe solar load, differential expansion, and dust penetration.
In regions like Riyadh and the Empty Quarter, exterior aluminum surface temperatures frequently exceed 78°C under direct solar radiation while indoor air conditioning maintains 21°C. Our profiles integrate 34mm multi-cavity Polyamide 66 reinforced with 25% fiberglass (PA66 GF25) thermal struts, effectively eliminating the bimetallic warping effect and preventing panel bowing.
The Arabian Peninsula experiences violent dust storms carrying particulate matter below 2.5 microns. Standard brush seals allow massive infiltration. Our accordion assemblies use a patented continuous co-extruded EPDM and Santoprene gasket network paired with dual active compression locks along both vertical meeting stiles and bottom drop-seals.
Marine environments along the Red Sea and Arabian Gulf combine 90%+ humidity with concentrated atmospheric chloride. We apply a multi-stage pre-treatment featuring chrome-free zirconium chemical conversion followed by Qualicoat Class 2 / Seaside-certified PVDF coatings, guaranteeing over 2,500 hours of continuous acetic acid salt spray (AASS) testing.
Blending contemporary open-concept architecture with essential cultural privacy and energy conservation.
Enabling Saudi homeowners to merge the internal family Majlis with shaded central courtyards or fountain patios during comfortable winter months, while sealing completely airtight during sweltering summer days.
High-end villas along the Red Sea in Jeddah demand expansive glass openings to showcase waterfront views without allowing marine corrosion to seize roller tracks or destroy mechanical gearing.
Trending commercial dining establishments in Riyadh Boulevard, Tahlia Street, and diplomatic quarters require dynamic bi-fold facades that fold away seamlessly during cool desert evenings to double guest capacity.
Supplying modular, rigorously tested, sustainable fenestration packages meeting the LEED Gold and Mostadam building certification frameworks mandated by NEOM, Red Sea Global, and Diriyah Gate developments.
Performance validation meeting Saudi Building Code (SBC 601 / SBC 602) energy conservation standards.

With over 25 years of specialized door and window engineering, Guangdong Dejiyoupin Doors and Windows Co., Ltd. (DERCHI) operates one of the most advanced digital manufacturing campuses in Foshan, China. We bridge global design flexibility with heavy industrial fabrication rigor.
Strategic movements driving the accelerated specification of heavy-duty accordion doors across the GCC region.
Under the Saudi Green Initiative and updated Saudi Building Code (SBC 601), municipal permits now demand rigorous fenestration SHGC (≤ 0.25) and low U-values. The industry is rapidly shifting away from non-thermally broken systems toward precision polyamide thermal barriers and solar control Low-E coatings.
Modern Gulf contemporary architecture heavily emphasizes floor-to-ceiling glass assemblies spanning upward of 3.8 to 4.2 meters. Architects are replacing standard sliding patio doors with custom heavy-load accordion systems that completely fold away into concealed wall pockets, opening up to 90% of the structural aperture.
Integration with centralized smart villa automation (KNX, Crestron) is rising. Modern installations require multipoint concealed electromagnetic locks, motorized accordion push-button folding, and sensor-driven weather-retraction mechanisms that automatically close when regional sandstorm sensors trigger.
A structured, risk-mitigated supply chain protocol protecting project timelines from initial drawing approval to site arrival.
Our engineering team reviews your architectural door schedules, elevation drawings, wind-load parameters, and local building code criteria to recommend ideal profile depths and glass make-ups.
We generate precise shop drawings detailing structural anchor locations, threshold drainage details, floor-recess dimensions, and opening clearances for consultant and municipality sign-off.
Profiles undergo four-axis CNC fabrication. Every bi-fold unit is pre-assembled, squared, and cycle-tested on our vertical testing rigs before dismounting, ensuring 100% mechanical alignment.
Packed in reinforced, fully fumigated steel-framed plywood crates with desiccant protection, ready for ocean freight to Jeddah Islamic Port or King Abdulaziz Port Dammam with full SABER compliance support.
Direct answers regarding SABER clearance, thermal compliance, custom configurations, and logistics to the Kingdom.
Yes. All our aluminum profiles, tempered glass units, and hardware sets are eligible for SASO Conformity Assessment. We coordinate directly with accredited certification bodies (such as TÜV, Intertek, or SGS) to issue the Product Certificate of Conformity (PCoC) and Shipment Certificate of Conformity (SCoC) via the official SABER platform prior to vessel departure.
Unlike conventional U-channel recessed bottom tracks that accumulate blown desert dust, our GCC-specific systems feature an elevated self-draining stainless steel track with dual nylon brush sweeps on each roller carriage. The sweep continuously pushes particulate matter away during opening and closing cycles, while concealed bottom drain channels evacuate fine dust.
By pairing our 85mm thermally broken profile (incorporating 34mm PA66 GF25 thermal struts) with double-glazed Low-E units (6mm Solar-Control Low-E + 16Ar + 6mm Clear Tempered), we achieve a total system U-value of 1.4 W/m²·K. For ultra-low energy ratings, triple-glazed configurations reach down to 1.1 W/m²·K with SHGC < 0.22, surpassing Saudi energy conservation codes.
Our reinforced commercial heavy-duty series can support individual panel heights up to 4,200 mm and panel widths up to 1,200 mm, with single panel weights up to 160 kg. Total continuous accordion door openings can extend beyond 15 meters using multi-panel configurations (e.g., 8-panel, 10-panel bi-parting or stacking in one direction).
Our packaging protocol is engineered for intercontinental sea transit. Each door sash is wrapped in protective foam film, perimeter corner protectors, and heavy plastic shrink-wrap, then packed inside custom-built, fully enclosed steel-framed wooden crates. Glass units are packed with moisture-absorbing silica gel desiccant packs to prevent condensation damage during passage through tropical waters.
Yes. Every consignment includes detailed, English/Arabic numbered installation manuals, anchor schedule blueprints, and 3D exploded assembly diagrams. Furthermore, our senior technical engineering team offers live remote video commissioning support and technical coordination during your local working hours (GMT+3) to ensure error-free track leveling and gasket alignment.
