Export-Grade Architectural Portfolios
Featured CE Certified Aluminium Door Systems
Our precision-milled aluminum rear entrances, French patio casements, and sliding barrier assemblies are customized for the architectural demands of Nur-Sultan, Almaty, Shymkent, and Atyrau.
Local Climate Adaptation & Engineering
Engineered for Central Asia's Extreme Thermal & Structural Realities
In Kazakhstan, back doors cannot simply replicate mild-climate designs. Rear entrances must endure steep temperature swings ranging from -40°C in winter blizzards to +40°C in dry summer heat, resisting high wind pressures across open steppe zones.
Sub-Zero Thermal Barrier (Polyamide PA66 GF25)
Standard PVC seals turn brittle and crack when exposed to severe northern Eurasian frosts. DERCHI aluminum back doors incorporate 34mm to 42mm multi-chambered polyamide strips, eliminating cold bridging and preventing interior ice condensation even during prolonged -35°C frosts in Astana.
High Steppe Wind Load & Air Impermeability
Kazakhstan's vast landscapes experience fierce wind shear (Class 4 / Class 5 according to EN 12210). Our door systems utilize reinforced 6063-T6 architectural alloy frames and seamless triple EPDM vulcanized sealing gaskets to ensure absolute water tightness and zero air infiltration during driving dust or snowstorms.
RC2/RC3 European Standard Anti-Burglary
Backyard doors, garden entries, and service portals are prime entry points for unauthorized intrusion. DERCHI integrates German-engineered multi-point hardware (Siegenia / Hoppe / Roto) combined with anti-drill cylinders and laminated P4A safety glass, providing private residences with robust protection.
| Performance Characteristic | Test Standard | DERCHI Engineering Specification | Compliance Benefit for Kazakhstan |
|---|---|---|---|
| Thermal Transmittance (U-Value) | EN ISO 10077-1 / 2 | Uw ≤ 0.85 – 1.2 W/(m²·K) with Argon Triple Low-E | Complies with Kazakh SNiP RK 2.04-05 building thermal envelope codes |
| Air Permeability | EN 12207 / GOST 26602.1 | Class 4 (600 Pa maximum test pressure) | Eliminates steppe wind drafting and heat loss through thresholds |
| Water Tightness | EN 12208 / GOST 26602.2 | Class 9A / E1050 (Static water pressure resistance) | Zero water penetration during heavy spring thaw and driving rain |
| Sound Reduction Index | EN ISO 10140-2 | Rw = 38 dB – 44 dB Acoustic Damping | Blocks external courtyard noise, wind howl, and industrial ambiance |
| Wind Load Resistance | EN 12210 / GOST 26602.5 | Class C4 / B5 (Deflection limit < 1/300) | Prevents sash warpage in open residential low-rise villa developments |
Strategic Market Evolution
Kazakhstan Fenestration Trends: The Transition to High-Performance Aluminium
Urban development programs like "Nurly Zher" and the modernization of residential architecture across Kazakhstan have reshaped developer procurement. Traditional PVC profiles and heavy cold-rolled steel doors are rapidly giving way to thermally broken aluminum.
1. Decarbonization & Energy Efficiency
With heating tariffs climbing and updated municipal energy efficiency quotas taking effect across Almaty and Astana, developers are choosing triple-glazed, argon-filled aluminum systems to lower building lifecycle heating footprints.
2. Slim Sashes & Maximized Daylighting
Modern luxury villas in the Medeu and Bostandyk districts increasingly favor minimalist slim-profile rear casements, bringing maximum natural light into back gardens and verandas without sacrificing thermal comfort.
3. Integrated Smart Home Ecosystems
Demand for biometrics, digital passcodes, and hidden motorized operators has surged. DERCHI door leaves come factory-routed for European smart locks, motorized seals, and concealed sensor channels.
4. Fluorocarbon & Anodized Longevity
Intense solar radiation in southern Kazakhstan can discolor and degrade conventional PVC foil finishes. Our AkzoNobel architectural powder-coated and PVDF finishes provide a 20-year colorfast guarantee against UV exposure.
Direct From Foshan Production Hub
Precision Fabrication Backed by DERCHI Scale
Produced by Guangdong Dejiyoupin Doors and Windows Co., Ltd., DERCHI brings 25 years of engineering precision to commercial partners, architectural firms, and wholesale dealers across Kazakhstan.
180,000㎡ Modern Production Base
Equipped with computerized multi-axis CNC machining centers, automated corner-crimping units, and advanced anodizing lines, our production facilities process over 600,000 square meters of fenestration products annually.
CE, ISO9001, AS2047 & UL Standards
Our products comply with EN 14351-1 European CE marking, North American UL testing, and Australian AS2047 benchmarks. Every profile batch undergoes rigorous alloy composition testing and salt spray verification.
China-Europe Railway Express Logistics
Foshan to Almaty/Astana rail routes via Khorgos or Alashankou deliver typical transit times of 14 to 18 days. Full export crating, vapor-sealed wrapping, and reinforced edge guards prevent transport-related vibration damage.

Kazakhstan Procurement: Common Commercial & Technical Questions
Clear answers regarding customs documentation, Eurasian Economic Union (EAEU) compliance, logistics channels, and cold-climate installation.
How do DERCHI aluminium back doors prevent condensation and frost during Kazakh winters?
Our systems use high-grade polyamide thermal breaks (PA66 GF25) up to 42mm in depth, structurally isolating the exterior aluminum skin from the interior sash. Combined with warm-edge spacer bars and triple-pane Low-E insulated glazing units filled with 90% Argon gas, the internal surface temperature stays well above dew point, preventing condensation even when exterior temperatures drop to -35°C.
What certifications and technical documentation do you supply for customs clearance?
We provide comprehensive export dossiers including full CE Declarations of Performance (DoP under EN 14351-1), ISO9001 factory certificates, Certificate of Origin (Form A), verified packing lists, and detailed shop drawings. These simplify EAC conformity evaluations and local architectural approvals across Kazakhstan.
What are the rail freight transit times and shipping routes to Almaty or Astana?
Shipments are loaded directly into containers at our Foshan manufacturing base and moved via the China-Europe Railway Express (CRE) through the Khorgos or Alashankou dry ports. Average transit times range between 14 and 18 days, significantly faster than traditional ocean routes and ideal for time-sensitive commercial projects.
Can you customize oversized dimensions and asymmetrical back door openings?
Yes. Every door is engineered to your specific door schedule. Our internal engineering department provides free AutoCAD and Revit shop drawings detailing sashes, transoms, sidelights, floor threshold transitions, and reinforcing mullions for oversized openings up to 3.2 meters in height.
What threshold designs are recommended for heavy snow accumulations?
For rear garden and patio entrances exposed to heavy winter drifts, we recommend our thermally broken low-profile barrier-free thresholds (under 20mm) fitted with integrated drainage weep channels and dual-recessed EPDM sweep seals. This keeps snowmelt from freezing against the interior sill.
How are doors protected against damage during multi-modal transit?
All doors undergo protective film wrapping, corner polystyrene edge capping, multi-layer vapor barrier shrink film, and are packed into fully enclosed, fumigated solid plywood export crates. Structural steel banding within the shipping container prevents load shifts across rough rail routes.
