Engineering Steel-Look Crittall Aesthetics with High-Performance Aluminium for Turkey's Built Environment
The iconic Crittall steel window aesthetic, recognized globally for its slender horizontal glazing bars, crisp grid divisions, and timeless industrial character, has become a cornerstone of contemporary architecture throughout Turkey. However, historic hot-rolled solid steel fenestration presents severe structural and thermal liabilities when deployed in Turkey's diverse macro-climatic landscape. Solid steel profiles have elevated thermal conductivity (roughly 50 W/m·K), triggering excessive interior condensation, perimeter mould formation, and chronic thermal bridging during Anatolian winters, while inducing severe internal heat gain under Mediterranean summer sun.
As a leading Chinese OEM/ODM extrusion and window manufacturing partner with over 25 years of engineering authority, we deliver an advanced alternative: Thermally Broken Architectural Aluminium Crittall Window and Screen Systems. By engineering bespoke 6063-T6 virgin aluminium extrusions with integrated glass-fiber reinforced polyamide (PA66 GF25) thermal insulation bars, our fenestration replicates the ultra-thin 28mm to 36mm sightlines of traditional hot-rolled steel while delivering exceptional U-values (Uw down to 1.1 W/m²·K), certified seismic tolerance, and marine-grade corrosion resistance.
1. Precision Structural Extrusions & Polyamide Thermal Break Technology
Our OEM/ODM aluminium Crittall window profiles are extruded using high-purity architectural grade 6063-T6 alloy with a tensile strength exceeding 205 MPa and yield strength greater than 170 MPa. To guarantee total compliance with Turkey's national energy performance standards (TS 825 “Thermal Insulation Requirements in Buildings”), we utilize multi-chamber thermal breaks spanning 24mm to 34mm in depth. These high-density polyamide barriers halt thermal conductivity between external and internal profile envelopes, preventing condensation even during sub-zero conditions in Ankara, Sivas, and Erzurum, while keeping interior surface temperatures comfortable.
2. Glazing Assemblies, Solar Control & Acoustic Attenuation (Rw)
Turkey's high urban density, notably along the E5 and TEM highways in Istanbul or Central Izmir, combined with high solar irradiance in Southern regions like Antalya and Bodrum, necessitates tailored glazing packages. Our Crittall profiles feature customizable glazing pockets accommodating 24mm to 44mm double- and triple-glazed insulated glass units (IGUs). Assemblies incorporate low-emissivity (Low-E) pyrolytic or magnetron sputtered coatings, warm-edge composite spacers, and 90% argon gas fills. For active commercial districts and luxury apartments, we engineer laminated acoustic PVB interlayers achieving sound insulation performance ratings of up to Rw 42 dB, effectively decoupling street acoustics from luxury living environments.
3. Seismic Deflection Engineering & Turkish Building Code (TBDY 2018)
Building in Turkey requires uncompromising structural engineering due to strict earthquake building codes (TBDY 2018 “Türkiye Bina Deprem Yönetmeliği”). Our OEM/ODM engineering division supplies fully customized anchor bracket systems, perimeter expansion joints, and continuous EPDM vulcanized co-extruded gaskets that accommodate inter-story seismic drift and dynamic building deflection without causing glass panel shattering, perimeter seal rupture, or frame racking. Every window assembly is modelled using FEA (Finite Element Analysis) to withstand localized wind pressure benchmarks exceeding Class C5 / AS 2047 N6 ratings.

Why Turkish Architects & Developers Are Shifting to Aluminium Crittall
Macro shifts in the Turkish construction and real estate sectors are driving demand toward high-performance, precision-manufactured aluminium steel-look systems.
Industrial Heritage Revival
Turkish boutique hotels, creative agency headquarters, and upscale hospitality spaces in Nişantaşı, Kadıköy, and Alsancak demand vintage industrial grid aesthetic with contemporary acoustic performance and seamless motorized ventilation.
Weight Reduction for High-Rises
Unlike steel profiles that introduce structural dead-load issues in multi-story developments, high-strength aluminium reduces frame weight by approximately 65%, simplifying crane operations, facade engineering, and seismic calculations.
Zero-Rust Longevity
Steel windows in coastal Turkey (such as the Bosporus, Prince Islands, or Aegean shores) suffer from rust creep, demanding constant repainting. Our powder-coated aluminium profiles offer zero-maintenance, 25-year structural corrosion resilience.
Green Building & LEED Credits
Turkey ranks among the top 10 countries globally for LEED green building certifications. Our 100% recyclable billet alloys and energy-efficient thermal-break designs directly contribute to LEED and BREEAM energy performance credits.

Frequently Asked Questions by Turkish Importers, Architects & Builders
Clear, expert responses addressing common technical, regulatory, logistical, and import queries for sourcing OEM/ODM aluminium Crittall windows from China into Turkey.
Q1: Do your aluminium Crittall windows comply with Turkey’s TS 825 insulation standard?
Yes. By pairing our polyamide thermal break aluminium profiles with high-performance double or triple insulated glass units (argon gas filled with Low-E soft coatings), our systems attain Uw values as low as 1.2 – 1.4 W/m²·K. This fully complies with and exceeds the requirements for all Turkish climate zones (Zone I Marmara/Aegean through Zone IV Eastern Anatolia).
Q2: What customs documentation and trade certificates do you provide for Turkish import clearance?
We supply comprehensive export documentation to ensure frictionless processing at Turkish customs (Gümrük Müdürlüğü). This includes CE Declaration of Performance (DoP), commercial invoice, packing list, certificate of origin, Bill of Lading, and fumigation certificates for all timber shipping crates in accordance with ISPM 15 standards.
Q3: Can you fabricate custom muntin bar grid designs to match historical projects in Istanbul?
Absolutely. As an OEM/ODM manufacturer, we offer both True Divided Lites (TDL) with individual glass lites and Simulated Divided Lites (SDL) featuring internal duplex spacer bars and external aluminium heritage glazing bars. We replicate authentic 19th and 20th-century proportions from Pera, Beyoğlu, and Balat architectural archives.
Q4: How do your finishes resist the corrosive marine environment of Bodrum and the Bosphorus?
We apply Qualicoat Class 2 certified architectural powder coatings and Qualicoat Seaside pre-treatments, as well as 25-micron architectural anodized finishes. These surface treatments withstand continuous saltwater mist, high UV radiation, and environmental pollutants without fading, chalking, bubbling, or edge-peeling.
Q5: What are the standard lead times for manufacturing and ocean shipping to Turkish ports?
Our standard production lead time is 25 to 35 business days following final CAD shop drawing approval and deposit receipt. Ocean freight transit from Shenzhen or Nansha ports to major Turkish container terminals (Ambarlı Istanbul, Mersin, or Alsancak Izmir) typically spans 24 to 32 days, providing a predictable timeline for construction managers.
Q6: What is the Minimum Order Quantity (MOQ) for custom OEM/ODM architectural orders?
We support both bespoke luxury villa orders and large-scale multi-family developments. Our typical MOQ is 30 square meters for customized residential projects. For large commercial projects requiring custom extrusion dies, our engineering division works closely with you on optimized batch manufacturing.
Q7: How are oversized units packed to prevent damage during long ocean transit?
Every window and door system is fully protected using multi-layer PE protective film, impact-resistant corner guards, bubble wrap encapsulation, and heavy-duty ISPM-15 compliant fully enclosed plywood crates with internal steel-strapping and vibration dampening supports to ensure zero transit damage.
Q8: Do you provide site installation guidance or engineering support for Turkish contractors?
Yes. Every order is delivered with comprehensive English installation manuals, 3D exploded assembly diagrams, anchoring schedules, and video walkthroughs. Our dedicated project engineers provide real-time remote technical support via video conference during Turkey business hours.
