Technical Rigour
Anti-Corrosive S350GD+Z Steel Specification
Our production facilities utilize certified S350GD+Z hot-dip galvanised structural steel with 275 g/m² zinc coating. This delivers exceptional corrosion resistance even in harsh coastal and high-humidity environments.
- Seismic Resilience: Rated for Richter Scale 8+ active earthquake zones.
- Wind Load Capability: Engineered to withstand wind loads up to 150 km/h.
- Thermal Efficiency: Integrated A1 rockwool / Polyurethane insulation sandwich panels achieving minimal thermal bridging.
- Fire Rating: Up to 120-minute structural fire rating on exterior wall assemblies.
Export Efficiency
Optimized Containerized Sea Freight Packaging
Structural components are precision-punched, CNC-coded, and flat-packed in high-density bundles at our Kocaeli factory near Istanbul sea ports. This reduces shipping volume by up to 40% compared to traditional structural units.
- Clear step-by-step assembly drawings and component matching tags.
- Full export documentation including CE conformity and mill test certificates.
- Rapid installation schedules using standard bolt connection technology.

Frequently Asked Questions on Steel Building Construction
Prefabricated steel structures offer unmatched strength-to-weight ratios, rapid bolt-together site assembly, zero material shrinkage, complete resistance to pests and rot, and superior longevity compared to timber or conventional brick mortar construction.
Our cold-formed and structural steel buildings are custom engineered for specific site parameters, including heavy snow load regions, high-wind hurricane areas (up to 150 km/h), and active seismic zones (Grade 8+). High-density rockwool wall cores provide insulation for temperatures from -40 °C to +55 °C.
Manufactured under strict ISO 9001 and ISO 14001 quality controls with hot-dip galvanised structural steel profiles, Nexa Prefab steel buildings deliver an engineered design service life of 50 to 70+ years with minimal maintenance required.
Standard steel building packages finish production within 20 to 30 working days following technical drawing approval. Our Kocaeli factory's proximity to major Marmara ocean terminals ensures ocean transit times of 7–14 days to Middle Eastern ports, 10–20 days to Africa, and fast road transport across Europe.
Turkish Steel Manufacturing Hub
Premier Prefabricated Steel Building Manufacturer in Turkey
As international construction programs demand accelerated delivery schedules and strict environmental compliance, prefabricated steel building systems from Turkey have emerged as the premier choice for international procurement managers, real estate developers, and civil engineering contractors.
Nexa Prefab combines advanced CNC roll-forming technology with expert structural engineering to produce light-gauge cold-formed steel houses, multi-storey residential complexes, commercial offices, and industrial metal warehouses. Operating out of Kocaeli — the manufacturing heartland of Turkey — our factory maintains rigorous quality inspection protocols at every stage, from raw steel coil verification to zinc coating thickness audits and pre-shipment trial assemblies.
Commercial, Residential & Institutional Steel Structures
Whether deploying single-family steel homes or multi-thousand square meter workforce accommodation camps, our structural systems adapt seamlessly to local building codes across Europe, the Middle East, Africa, and the Americas. The lightweight nature of cold-formed steel significantly reduces foundation depth requirements, cutting total civil work expenditure and project timelines by up to 50%.
