Steel-Frame Housing: Seismic Safety, Speed of Construction, Modern Architecture
Altıntaş Çelik offers a high-performance alternative to reinforced concrete in residential construction. The steel frame system allows faster assembly, reduced structural weight and superior seismic performance. All elements are manufactured at our Pınarbaşı/İzmir factory under quality control and assembled on-site in a planned sequence.
Multi-Storey Steel Frame Residential Buildings
Steel frame structures for 2–8 storey residential buildings perform far better than reinforced concrete in earthquake zones. The steel skeletal structure absorbs seismic energy through its ductility — this is a critical performance advantage in Türkiye's high-seismicity regions. The system is compatible with all facade types (brick, sandwich panel, curtain wall) and works with conventional RC or composite slab floor systems.
- Superior seismic performance: ductile frame absorbs earthquake energy
- 30–40% faster erection vs reinforced concrete frame
- Lighter structure → smaller foundation dimensions and lower foundation cost
- Flexible floor plans: column grid chosen to suit apartment layouts
- Compatible with brick, sandwich panel and curtain wall cladding
- Suitable for apartment blocks, detached villas, student residences and care homes
Advantages of Steel Frame Housing
Why Choose Steel for Residential Construction?
Earthquake Safety
Steel ductility absorbs seismic energy without the brittle failure modes of reinforced concrete. Frame design complies with TBDY 2018 high-ductility class requirements.
Faster Completion
Factory production runs parallel to site preparation. The steel frame rises floor by floor, 30–40% faster than a comparable RC structure, meaning earlier occupancy.
Lower Foundation Cost
A steel frame is around 25–35% lighter than an equivalent RC structure. Smaller column and foundation sections translate directly to cost savings on foundations.
Architectural Flexibility
Column grid can be selected freely, enabling open-plan living areas and various apartment type combinations within the same building.
Factory Quality Control
All structural elements undergo dimensional and weld quality inspection before leaving the factory. Site connections are fully bolted — no on-site welding.
Long Service Life
Properly protected and maintained steel structures have a service life exceeding 50 years without significant structural degradation.
Our Process for Your Residential Steel Building
From Concept to Handover
- 1
Demand Analysis & Preliminary Design
Number of storeys, floor area, apartment mix and seismic zone data are collected. Structural system options are presented with preliminary cost estimate.
- 2
Structural Engineering
Column and beam sections, connection details, floor slab type and seismic calculations per TBDY 2018 are finalised. Architectural and structural drawings are coordinated.
- 3
Factory Manufacturing
All frame elements are produced at our Pınarbaşı/İzmir plant. Dimensional tolerances and weld quality are inspected at every stage. Elements numbered and shipped in erection order.
- 4
On-Site Assembly
Anchor plates positioned under surveyor supervision. Frame erected floor by floor with safety equipment. Project completed with occupancy permit inspections and as-built drawings.
