Engineered to meet stringent European standards (EN 14782, EN 1090-2) and optimized for rapid integration across heavy manufacturing, pharmaceutical cold supply, and structural logistics projects.
Cold-formed steel (CFS) profile sheets represent the fundamental structural diaphragm of modern pre-engineered steel buildings (PEBs), high-bay distribution hubs, and agricultural infrastructure across the Euro-Mediterranean and Middle Eastern corridors. In our advanced Turkish manufacturing hubs—spanning the Marmara and Aegean industrial clusters including Gebze, Dilovası, and Aliağa—our automated continuous cold roll-forming lines transform prime-grade structural strip steel into high-yield, low-weight profile geometries that comply rigorously with European standard EN 10346 (continuously hot-dip coated steel flat products) and EN 10143 (tolerances on dimensions and shape).
The manufacturing process utilizes multi-pass CNC bending roll stands designed to progressively impart plastic deformation into high-tensile base metals without exceeding the microstructural yield envelope of the protective zinc or aluzinc intermetallic alloy layers. Unlike standard hot-rolled structural steel, cold-rolled profile sheets exhibit localized strain hardening along rib corner bends, which increases the nominal yield point (fyb) of the section by up to 15% to 22%, yielding unmatched structural stiffness-to-weight performance.

For original equipment manufacturers (OEM) and brand licensors (ODM), custom profile geometry tooling is modeled using finite element elastic-plastic deformation simulations (FEA). This prevents longitudinal cambering, cross-sectional bowing, and flare during shearing, allowing our factory to deliver exact match configurations for imported European cladding machinery or specialized modular container assembly lines.
Turkey's unique geographic position bridges two continents while presenting intense microclimatic and tectonic challenges. From the high-salinity marine air of the Marmara and Mediterranean coastlines to the severe thermal swings of Central Anatolia and the high seismic hazards along the North Anatolian Fault Zone, profile sheets must be custom-engineered for localized environmental stresses.
In compliance with the Turkey Building Earthquake Code (TBDY 2018), industrial facilities in Organized Industrial Zones (OSBs) must minimize dead load atop structural frames. Cold-formed profile sheets combined with Rockwool or PIR cores provide an ultra-lightweight structural diaphragm that absorbs lateral seismic shear vibrations without brittle fracture or joint unseating.
Coastal logistics hubs and chemical storage yards located along the Gulf of İzmit and Aegean ports face ISO 12944 C4 to C5-M high corrosivity risks. We deploy dual-sided Aluzinc (AZ150) and 50-micron high-durability polyurethane or PVDF coated sheets that offer certified resistance to salt-spray fog testing exceeding 1,500 hours without red rust initiation.
Turkey’s southern agricultural valleys require continuous cold chain integrity from harvesting to air freight dispatch. Here, profiled metal sheets serve as external weather envelopes sheltering inner cryogenic panels. Incorporating high solar reflectance coatings (Total Solar Reflectance > 78%) significantly diminishes cooling chiller power consumption during torrid summer peaks reaching 46°C.
Leveraging roll-on/roll-off (Ro-Ro) shipping routes from Pendik and Çeşme to Trieste (Italy) and Toulon (France), as well as direct highway freight to the Balkans and the Levant, our Turkish factory eliminates 35-day oceanic transit backlogs from East Asia. Container-optimized profile nesting guarantees maximum cubic freight utilization and moisture-free vapor packaging.
The industrial building envelope sector in Turkey is navigating a dramatic structural transition driven by two mega-forces: regulatory seismic resilience mandates following recent Anatolian seismic events and the stringent European Union Carbon Border Adjustment Mechanism (CBAM). Our Turkish manufacturing methodologies are at the forefront of this evolution.
Traditional unreinforced concrete masonry infill walls demonstrated severe brittle collapse risks in recent tectonic analyses. Turkish engineering consultants and EPC specifiers are mandating 100% lightweight cold-formed steel perimeter skins and through-fixed trapezoidal diaphragms capable of accommodating high inter-story drift ratios (>1.5%) without structural loss of integrity.
As Turkish primary steelmakers transition from blast furnace (BOF) routes to renewable-powered Electric Arc Furnaces (EAF) using domestic recycled ferrous scrap, our cold-rolled profile sheets deliver industry-leading low embodied carbon metrics. We provide verified Environmental Product Declarations (EPD) that shield European buyers from CBAM carbon border tax liabilities.
Turkish industrial factories are aggressively executing the "Roof-Mounted SPP" (Güneş Enerji Santralleri - GES) national mandate. Our cold-rolled roof sheets feature reinforced trapezoidal crown geometries with engineered rib-flat widths that accommodate standing-seam non-penetrating solar clamps and direct load distribution up to 35 kg/m² of added dead load.
Operating as an integrated structural envelope manufacturer, our facilities bridge custom roll-forming craftsmanship with massive industrial scalability. We maintain end-to-end sovereignty over slitting, roll profile forming, foam compounding, and finished quality certification.
Over 10,000 m² combined daily production capacity across multiple continuous roll-forming lines, ensuring synchronized dispatch for large-scale multi-hectare industrial complexes.
Custom cut lengths up to 15.6 meters, bespoke crest embossing, micro-ribbing, off-pitch fastener punching, and custom color matches according to RAL Classic and RAL Design catalogs.
Certified Class A1 non-combustible Rockwool panel systems and Class B-s1,d0 fire-retardant polyisocyanurate (PIR) cores, rigorously validated in accredited European laboratories.
Optimized intermodal connectivity via Turkish deep-water ports and direct truck transit to Central/Western Europe, the Gulf Cooperation Council (GCC), and North African ports.
Our senior structural and procurement engineering teams address the critical structural, regulatory, and metallurgical questions routinely raised during project tendering and submittal reviews.
We primarily process structural continuous hot-dip coated steels conforming to EN 10346, including S250GD, S280GD, S320GD, and high-tensile S350GD (+Z/AZ). Structural design calculations are fully mapped to Eurocode 3 (EN 1993-1-3) for cold-formed thin-gauge members, incorporating post-buckling effective width methods for web and flange stiffeners under positive and negative bending moments.
For marine or industrial environments characterized by high sulfur and chloride contents (ISO 12944 category C4/C5), standard Z100 coatings are insufficient. We recommend minimum Z275 (275 g/m² total dual-surface zinc mass) or Aluzinc AZ150 (55% Al, 43.4% Zn, 1.6% Si) paired with a 25µm super polyester or 50µm polyurethane/PVDF topcoat to guarantee barrier and galvanic sacrificial protection for over 25+ years.
Yes. Through our specialized automated crimping roll-benders, we can manufacture convex and concave curved profile sheets from TR-27/200 and TR-38/151 cross-sections. Radius dimensions down to 1,500mm can be custom engineered to form continuous eaves-to-apex curved arches without external transverse lap joints, eliminating leak risks in aircraft hangars and sports complexes.
Every mother coil received from Tier-1 European and Turkish blast-furnace/EAF mills undergoes spectrometry verification, tensile elongation testing (ASTM E8 / ISO 6892-1), digital micrometer thickness audits (EN 10143 precision class), and MEK rub solvent tests. Factory Mill Test Certificates (EN 10204 Type 3.1) are issued with every export consignment, confirming full traceability.
Per international structural building codes, serviceability limit state (SLS) deflections are generally capped between L/200 and L/250 under characteristic live, wind, and snow combinations. For roofs bearing solar photovoltaic mounting arrays or sensitive ceiling finishes, we engineer profile thickness and purlin spans to meet a stricter deflection ceiling of L/300 to prevent dynamic fatigue on clamping brackets.
Wet storage stain (white rust) occurs when moisture penetrates nested profile bundles during maritime or overland freight. We prevent this by applying dry passivation (chemically inert inorganic or organic thin films), automated polyethylene stretch-wrapping, interleaved vapor corrosion inhibitor (VCI) paper, and heavy-duty steel angle edge protectors affixed atop solid timber skids.
