Hybrid composite core offering maximum structural rigidity, resistance against extreme dry solar radiation, and multi-point deadbolt physical security.
Designing fenestration for the Damascus basin requires addressing an extreme semi-arid continental climate characterized by severe diurnal temperature fluctuations, high summer solar irradiance, winter sub-zero frosts, and persistent airborne dust.
Damascus summer facade temperatures routinely exceed 58°C under direct solar radiation, dropping to 18°C at night. Standard aluminum extrusions warp under such cyclic thermal expansion. Our OEM slide systems integrate PA66GF25 polyamide thermal break strips with matching coefficients of linear expansion, preventing frame bowing and ensuring effortless sash glide year-round.
The semi-arid Barada Valley and proximity to the Syrian Desert expose exterior joinery to abrasive, ultra-fine dust (PM10 and PM2.5). Conventional sliding windows fail as grit clogs roller tracks. We manufacture custom aluminum slide windows featuring elevated stainless-steel monorails (SUS304) paired with dual-density high-fin woven pile weatherstripping and co-extruded EPDM gaskets.
In high-density districts like Mezzeh, Malki, Shaalan, and Abu Roummaneh, vehicular and commercial ambient noise reaches 75–80 dB. By combining our precision CNC corner-crimped frames with asymmetric double-glazed units (6mm Low-E + 12A + 8mm clear) or acoustic PVB lamination, our sliding assemblies deliver verified sound reduction of up to Rw 42 dB.

From post-war reconstruction projects to modern master-planned smart towers, Damascus represents a revitalized fenestration market requiring customized OEM engineering over commodity stock profiles.
The flagship development projects in south-west Damascus demand cutting-edge contemporary fenestration. Residential high-rises reaching 20+ stories face elevated wind pressures across the Ghouta plain. Our reinforced multi-track lift-and-slide systems enable wide floor-to-ceiling glass openings without structural chatter or wind whistling, supporting heavy solar-control Low-E insulated glazing units.
Preserving the vernacular courtyards of traditional Damascene homes while achieving thermal efficiency is an engineering art. Our custom extrusion tooling accommodates authentic arched headers, narrow mullion sightlines, and subtle wood-grain or textured bronze anodized finishes. Modern sliding configurations replace drafty, deteriorated single-glazed wooden casements without disrupting historic masonry lintels.
Electricity supply constraints across Syria have elevated passive thermal insulation from a luxury to a fundamental necessity. In winter, when municipal heating is constrained, our high-spec thermal break slide windows trap indoor radiant heat. In summer, spectrally selective Low-E coatings deflect up to 72% of infrared heat gain, maintaining habitable interior conditions with minimal reliance on intermittent AC.
Local Syrian fabricators have historically relied on imported Turkish or Lebanese extruded billets with manual hand-crimped assembly. However, shifting market economics and the demands of modern mixed-use developments have created key structural transformations:

Accredited compliance spanning European CE (EN 14351), American NFRC, Australian AS2047, Canadian CSA, Energy Star, and ISO 9001 quality management standards.
When contracting for multi-story towers or gated villa communities in Damascus, project schedules cannot tolerate shipping delays or out-of-square profile deliveries. DERCHI assigns a dedicated technical task force to every international contract:
Custom structural calculations for wind loads, glass deflection limits, and lintel load transfer, submitted within 72 hours of project schedule receipt.
Extrusions treated in German automated vertical powder lines using Qualicoat Class 2 hyper-durable polymers resistant to intense UV exposure and micro-abrasion.
Fully enclosed steel-strapped fumigated plywood crates with multi-layer protective PE film and moisture desiccants preventing salt-mist oxidation during transit.
Detailed answers addressing regulatory compliance, logistics routing, payment mechanisms, and technical performance specifications for custom aluminum window shipments into Syria.
Shipments from our Foshan facility typically depart through Nansha or Shenzhen ports. The most common maritime routing to Syria is via the Port of Latakia or Port of Tartus on the Mediterranean coast. Cargo clears customs at Latakia and is transported via secure overland transport along the M1/M2 highway corridor to Damascus (approx. 340 km). Alternatively, for select expedited commercial orders, transit via Beirut Port (Lebanon) with cross-border overland freight through the Masnaa border post to Damascus is routinely coordinated.
DERCHI possesses vast experience handling exports into the Levant. We provide all authenticated commercial documents including commercial invoices, packing lists with detailed crate dimension diagrams, certificates of origin issued by CCPIT, and bill of lading releases. We work flexibly with standard commercial terms (FOB China ports, CIF Latakia, or CFR Tartus) and accommodate payment structures through established third-country international banking channels or verified commercial Letters of Credit (L/C).
While uPVC has low natural conductivity, it suffers significant thermal dimensional instability in semi-arid zones like Damascus, where summer exterior glass temperatures exceed 55°C. Under intense Mediterranean UV and heat, uPVC profiles expand, distort, and eventually jam sliding mechanisms or crack at heat-welded corners. Thermal break 6063-T5 aluminum extrusions provide superior structural rigidity, withstand high wind loads, do not degrade under UV, and deliver identical or superior thermal insulation when configured with polyamide PA66GF25 barrier strips.
Yes. Every production run is 100% custom-engineered (OEM). We match specific profile cross-sections, frame depths (such as 80mm, 100mm, 120mm, or 135mm architectural series), narrow sightlines, integrated Georgian bars, external arch profiles, or integrated roller shutter guide channels. Finish choices include Qualicoat powder coatings in any standard RAL color, deep architectural bronze anodizing, and photorealistic sublimated Italian wood-grain finishes.
Standard sliding windows fail in dusty climates because dirt accumulates in low recesses, wearing down nylon wheels. DERCHI OEM sliding systems incorporate raised stainless-steel tracks with sloped sill bases that automatically channel dust and rainwater outward through hidden non-return baffle drain flaps. Double or triple high-density silicone-treated polypropylene brush piles with central fins create an airtight, dustproof compression barrier along all moving sash edges.
For custom residential villa projects, our MOQ is as flexible as 50 square meters (providing complete window/door packages for single luxury homes). For large residential and commercial developments, we supply 20ft and 40ft High Cube containers (typically 300 to 650 m² per container depending on glazing configurations and knocked-down vs. pre-assembled delivery). Full container load (FCL) orders benefit from substantial freight economies and reduced handling risks.
Yes. For multi-story commercial and residential towers, our structural engineering department produces comprehensive wind-load calculation books based on the building height, terrain roughness, and project design parameters. We calculate mullion moment of inertia (Ix, Iy) values to ensure deflection does not exceed L/250 or L/300 under local maximum wind loads, guaranteeing structural safety during extreme Mediterranean storm fronts.
We employ a multi-tier protective packaging protocol. Each individual frame is wrapped with 0.1mm protective film and encased in high-density pearl cotton corner guards. Glass units are separated by non-residue cork pads and anti-scratch sheets. Assemblies are loaded inside fully enclosed, fumigated solid wood cases reinforced with steel strapping. Each crate contains desiccant packets, and internal container load anchoring prevents shifting during ocean transit.
Whether you require precision shop drawings for a residential villa refurbishment in Abu Roummaneh or container-load OEM sliding window shipments for commercial developments in Marota City, our Foshan factory engineering team provides complete technical estimates and structural calculations within 24 hours.
