Fabricated from primary 6063-T5 aluminum alloy billets and industrial-grade 304/316 marine stainless steel security mesh, engineered for thermal efficiency, high wind loads, and forced-entry deterrence.
Addressing structural integrity, forced-entry knife-shear testing, anti-corrosion finishes, and climatic insulation for Central Asian architectural projects.
DERCHI aluminium security mesh doors are engineered using heavy-wall 6063-T5 aluminum extrusions with a minimum profile thickness of 2.0mm to 2.5mm. The infill screen consists of high-tensile 304 or marine-grade 316 stainless steel wire mesh (wire gauge 0.8mm to 1.0mm, 11×11 or 12×12 mesh count per inch). The mesh passes the stringent Australian AS5041 Knife Shear Test and Dynamic Impact Test (exceeding 5 consecutive impacts of 100 Joules), ensuring that intruders cannot slice, kick, or pry the screen loose from the primary entrance framing.
For main entrance installations requiring unbroken thermal envelopes, our hybrid mesh-and-glaze entry solutions utilize Technoform® polyamide PA66 reinforced with 25% fiberglass. This effectively eliminates thermal bridging across extreme interior-to-exterior temperature gradients. While the outer stainless steel security mesh allows uninterrupted daytime cross-ventilation, an inner operable double- or triple-glazed IGU (filled with 90% Argon gas) seals the home against thermal loss during freezing winters down to -25°C, providing an overall thermal transmittance value of UD ≤ 1.3 W/(m²·K).
To resist Central Asia’s abrasive mineral dust and solar ultraviolet radiation, all profiles are treated through an automated 12-stage pre-treatment wash before receiving architectural powder coatings from AkzoNobel or PPG. Certified under Qualicoat Class 2 and AAMA 2604/2605 guidelines, these electrostatic coatings withstand 3,000 hours of continuous salt-spray testing and accelerated QUV weathering, ensuring zero chalking, flaking, or gloss loss when exposed to the alkaline desert soils common in Samarkand and Bukhara.

Solving real building envelope vulnerabilities across Tashkent’s rapid urban expansions, traditional courtyard estates, and desert hospitality corridors.
Elite residential villas in Tashkent require prominent main entryways that convey prestige without sacrificing privacy or perimeter defense. DERCHI's custom oversized pivot and double-leaf swing doors feature internal security mesh panels concealed behind bespoke laser-cut cast aluminium lattice or Italian minimalist glass leaves. This allows homeowners to safely open their primary timber or insulated core doors during temperate autumn and spring evenings, enabling cross-ventilation while preventing outdoor pests and uninvited observers from breaching the foyer.
Central Asian vernacular architecture centers on the internal courtyard (Hovli), which traps fresh air at night to cool surrounding family living quarters. Installing an industrial-grade aluminium security screen door at the threshold of the primary hall (Aivan) provides continuous natural airflow without letting fine desert loess sand or insects invade interior carpeting. The 0.8mm woven wire mesh stops flying debris and pollen while maintaining optical clarity toward the courtyard fountain.
Boutique hotels catering to Silk Road tourists face high foot traffic and rigorous air exchange demands. DERCHI commercial mesh-integrated entrance swing doors combine reinforced bottom kick-plates, Dormakaba/Geze heavy-duty overhead concealed closers, and multi-point master-keyed locking systems. They provide durable resistance to guest luggage impacts while presenting a crisp architectural appearance that coordinates with surrounding storefront glass and ventilated façades.
Why leading developers, architects, and state housing initiatives are pivoting from heavy wrought-iron grilles to high-precision architectural aluminium systems.
With Uzbekistan’s escalating modernization of municipal energy utilities and national building codes, insulation standards are rising rapidly. Traditional single-layer uninsulated steel gates and ornamental iron doors are being superseded by thermally separated aluminum systems. Main doors incorporating hidden security screens within thermally isolated frames allow builders to achieve strict U-factor targets without adding bulky exterior metal security bars that fail fire egress codes.
Historically, residential developers in Central Asia welded decorative iron grilles across external doors and loggias to prevent burglaries. Today's modern buyers demand clean sightlines and uncluttered facades. High-tensile stainless steel security screen doors deliver superior forced-entry protection (exceeding 450 MPa tensile resistance per wire strand) while appearing visually transparent from inside, aligning perfectly with modern Eurasian architectural design principles.
Projects across "Tashkent City" and New Tashkent master plans are standardizing on home automation and secure biometric authentication. DERCHI entrance mesh assemblies are custom-machined with internal wiring raceways to integrate 3D facial recognition, Tuya/Zigbee motorized multipoint lock mortises, and magnetic door sensors. This guarantees automated locking even while the main door is set to ventilating mesh latch mode.
