Specially manufactured to withstand severe alpine winters, blistering summer desert heat, high UV radiation, and heavy fine-sand particulate infiltration across Afghanistan.
Civil reconstruction projects, luxury private compounds, municipal facilities, and commercial hubs in Kabul, Balkh, Herat, and Nangarhar encounter severe environmental stressors that render standard fenestration obsolete within years. Our export systems pair metallurgical precision with advanced polymer optics.
Our extrusions employ high-purity virgin aluminum billet with yield strengths exceeding 170 MPa. Designed with wall thicknesses between 1.8mm and 3.0mm, these systems resist intense windward deflection along mountain passes while maintaining rigid alignment across multi-meter door leafs.
Poly-methyl methacrylate (PMMA) infill panels provide 17 times the impact resistance of annealed silicate glass at half the structural weight. Specially treated with cross-linked UV stabilizers, our panels avoid solar yellowing and surface crazing despite Afghanistan's extreme ultraviolet index.
Glass-fiber reinforced polyamide isolators break structural thermal conductance. This thermal barrier drops frame U-values below 1.6 W/m²·K, preventing severe condensation and frost bridging during freezing Kabul winters while slashing commercial air-conditioning loads in midsummer.
The "Wind of 120 Days" (Bad-i-Sad-o-Bist Roz) creates high airborne concentrations of abrasive silt in Western Afghanistan. Our door units utilize dual-density co-extruded EPDM continuous perimeter gaskets with finned pile weatherstripping to halt microscopic dust penetration completely.
Security is non-negotiable for administrative and residential structures. Integrating DERCHI’s patented Four-Side Six-Point locking mechanics, each sash locks simultaneously into top, bottom, and lateral jamb channels using anti-saw hardened manganese steel pins.
Exposed profile surfaces are finished with Qualicoat Class 2 certified architectural powder coats or fluoropolymer PVDF coatings exceeding 60 microns. This barrier resists continuous salt-alkali wind abrasion, surface scratching, and cyclical thermal expansion from -25°C to +50°C.

Different provinces present contrasting engineering challenges. Our fenestration systems are configured according to local altitude, diurnal thermal swings, and architectural archetypes.
Kabul sits at 1,790 meters altitude where winter temperatures plummet to -15°C while solar radiation remains intense. Systems feature multi-chamber thermal isolators that prevent condensation pooling, thermal profile stress cracking, and acoustic pollution across metropolitan districts like Wazir Akbar Khan and Shahr-e Naw.
The infamous 120-day high-velocity desert winds subject facades to sustained gale-force grit. We specify reinforced acrylic panels that resist shatter hazards from airborne debris, coupled with brush-free vulcanized EPDM seal chambers that prevent sand particles from locking internal roller bearings.
Southern regions experience ambient summer peaks exceeding 45°C. Systems incorporate double-glazed solar-reflective acrylic or spectrally selective Low-E insulated glass. These layers reflect radiant infrared energy while preserving indoor cooling loads for private villa complexes and logistics terminals.
As the trade nexus with Central Asia through Hairatan, Northern projects demand high-turnover institutional durability. Heavy-duty pivot entrance systems and sliding doors with stainless steel tracks provide zero-jam performance under constant commercial and industrial traffic.
The architectural landscape in Afghanistan is shifting rapidly from makeshift site-fabricated frames to factory-engineered architectural systems with documented technical certifications.
Traditional Afghan cultural architecture places prime importance on personal privacy (Mahramiyat). Translucent, frosted, and patterned cast acrylic door elements are replacing outdated wooden screens. They maximize diffuse natural illumination inside family quarters without compromising external visual obscurity.
With electrical grid reliability varying and diesel generation costs high, developers of commercial plazas and hospitals cannot afford thermal energy bleed. High-performance thermal-break aluminum doors and double-glazed units offer paybacks in heating/cooling efficiency within 24 months.
Due to local raw metal shortages and a scarcity of precision tooling in domestic workshops, major contractors in Kabul and Herat are purchasing completely knock-down (CKD) or pre-assembled systems directly from certified Chinese manufacturers, guaranteeing factory tolerances.
Shipping high-precision glazed aluminium fenestration to a landlocked destination requires hardened crating protocols and proven logistics pathways to bypass severe mountain highway vibration and customs hold-ups.
Finished frames and acrylic panels undergo 360-degree quality inspections, barcoded indexing, protective PE film wrap, shock-absorbent corner protectors, and sealed fumigated timber case crating.
Ocean freight routes from Pearl River Delta ports (Nansha/Shekou) to Port of Karachi or Port Qasim, Pakistan. Goods transfer under Afghan Transit Trade (ATT) customs bond agreements.
Containerized truck convoys transit via Torkham border crossing for Eastern/Kabul deliveries, or Spin Boldak for Southern Kandahar distribution, with complete consular and commercial documentation.
Alternative intermodal transit via Central Asia (China-Kyrgyzstan-Uzbekistan corridor) terminating at the Hairatan rail dry port, facilitating direct distribution to Mazar-i-Sharif and Kunduz.
Headquartered in Nanhai District, Foshan—the global center of aluminum profile extrusion and architectural hardware engineering—DERCHI has dedicated over 25 years to manufacturing top-tier architectural systems for developers, contractors, and building material suppliers worldwide.
With an ultra-modern 180,000 m² industrial production campus, our robotic precision cutting, CNC corner crimping, and automated insulating glazing lines ensure absolute geometric accuracy according to approved architectural shop drawings.
For Afghan project developers, we offer end-to-end engineering support: structural wind-load simulations, thermal profile calculations, bespoke color matching (AkzoNobel & Tiger coatings), and complete installation guidance documentation.
Clear, definitive technical guidance addressing cross-border procurement, environmental longevity, and hardware reliability.
No. Standard commercial polystyrene panels yellow rapidly; however, DERCHI exclusively uses optical-grade cast PMMA acrylic treated with cross-linked benzotriazole UV stabilizers. It is guaranteed against measurable yellowing (Delta YI < 2) and tensile embrittlement for over 15 years in high-altitude environments like Kabul.
Our sliding tracks integrate elevated stainless steel monorails combined with self-cleaning brush seals and downward-sloped debris drainage channels. Airborne silt brought by seasonal winds is automatically swept aside during sash travel, preventing roller seizure.
Yes. Our engineering division follows an 8-stage CAD/BIM review protocol. We take your architectural blueprints and calculate wind load resistances, threshold clearances, thermal breaks, and structural anchorage layouts before submitting comprehensive shop drawings for client sign-off.
Manufacturing custom door orders takes approximately 20 to 30 days depending on profile finish and glass/acrylic specifications. Maritime transit from Foshan (via Nansha/Shekou) to Karachi takes 14 to 18 days, followed by 7 to 10 days for bonded overland cross-border trucking to Kabul or Kandahar.
All aluminum extrusions are wrapped in peelable low-tack protective polymer films, cushioned with edge protectors, bundled with moisture desiccants, and packed in reinforced, fully enclosed plywood crates built to withstand transshipment across steep mountain passes.
We work with international commercial banking networks accommodating confirmed Letters of Credit (L/C at sight), telegraphic transfers (T/T with staged milestones), and third-party escrow arrangements established through regional commercial hubs such as Dubai (UAE) or Istanbul (Turkey).
