The System That Defines Your Building's Outer Shell: Choosing the Right Roof and Facade
Altıntaş Çelik engineers steel roof and facade systems as engineering decisions integrated with the building's structural system. Roof slope, span distance, snow and wind zone data along with the usage scenario directly determine the structural system selection. All roof structures are produced at our Pınarbaşı/İzmir factory and our team handles on-site installation.
Lightweight Steel Roof Cladding Systems
Lightweight steel roof cladding systems serve a wide range of applications from large-span industrial buildings to agricultural facilities and warehouses. The foundation consists of factory-produced steel purlins and rafters; trapezoidal sheet, corrugated sheet or panel cladding is applied according to project requirements.
- Low structural weight with factory-produced steel purlins and rafters
- Trapezoidal sheet, corrugated sheet or panel cladding options
- Snow and wind load calculations included in the project
- Can also be applied as an additional roof to existing structures
- Quick assembly — much shorter installation time compared to reinforced concrete roofing
Truss and Barrel Vault Roof Systems
Truss roof systems are lattice structures that can carry loads over long distances without intermediate support in large-span buildings. In factory buildings, hangars, sports facilities and logistics warehouses requiring large interior spaces, the truss system is the preferred primary structural solution.
- Truss systems: 15–80 m column-free spans
- Project-specific truss geometry and load calculations
- Barrel vault: large spans with low material usage, aesthetic form
- Suitable for agricultural warehouses, hangars and sports facilities
- Complete factory manufacturing, on-site assembly only
Panel, Trapezoidal Sheet and Sandwich Panel Applications
The cladding material used for roofs and facades directly determines the building's energy efficiency, sound insulation and aesthetic appearance. At Altıntaş Çelik, we select and apply three fundamental cladding systems appropriate to each project.
- Trapezoidal sheet: fast assembly, wide color range, low cost
- Sandwich panel: thermal and acoustic insulation in one layer, ideal for cold storage and food facilities
- Polycarbonate panel: transparent roof and facade sections for natural lighting
- Renovation and cladding replacement in existing structures
Reasons to Choose Steel Roof & Facade Systems
Why Steel Roofing?
Fast Application
Factory-produced structures and procured cladding materials come together quickly on-site. Assembly time is significantly shorter than reinforced concrete roof systems.
Reduces Structural Weight
The lightweight steel roof system reduces column and foundation dimensions, providing cost savings across the entire project.
Insulation Flexibility
From trapezoidal sheets to sandwich panels, polycarbonate to rock wool systems — cladding options with different insulation performance levels for each building type.
Large Span Capability
With truss and barrel vault systems, spans of 15–80 m without intermediate support. The building interior remains completely free.
Renovation on Existing Structures
Aged or damaged roof and facade claddings are renewed without touching the structural system, minimally disrupting facility operations.
Standards-Compliant Design
Snow and wind load calculations, condensation analyses and thermal bridge details prepared in compliance with Eurocode and Turkish regulations.
We Are By Your Side at Every Stage of Your Roof & Facade Project
Our Working Process
- 1
System Selection & Engineering
Building span, snow and wind zone, usage scenario and insulation requirements are evaluated together to determine the most suitable structural system and cladding material.
- 2
Factory Manufacturing & Material Procurement
Roof structures (trusses, purlins, rafters) are produced at our Pınarbaşı/İzmir factory. Cladding materials are procured to project specifications and shipped in assembly order.
- 3
On-Site Assembly
Roof structures are installed following occupational safety protocols, then cladding is applied. For renovation on existing structures, a phased assembly plan minimizes disruption.
