Steel Constructions

From Engineering to Implementation: Steel Structure Manufacturing to International Standards

Aldem Çelik develops steel structure solutions that provide maximum structural integrity for projects of any scale, from industrial plants to energy infrastructure. We don’t just build steel frameworks; we manufacture high-strength structural systems designed to meet all static and fatigue requirements of your project.

Expertise for Critical Structural Projects

Our competence in steel structures is built on our ability to meet the most demanding engineering specifications.

Certified Manufacturing Capability

All production processes are carried out under the mandatory European standard EN 1090-2 (EXC4). This ensures that every structural element we produce fully meets the intended load capacity and geometric tolerances.

Design-to-Manufacturing Integration

We accurately transform detailed steel project outputs created in softwares. Whether it’s factory buildings or complex industrial frames, our expertise in welded constructions guarantees perfection in the final product.

Capacity and Process Diversity

Thanks to our extensive machinery and equipment, we can efficiently process a wide range of steel profiles, from large-span beams to heavy load-bearing columns, at high volume and speed.

Aldem Çelik provides not only a reliable steel structure supplier but also a manufacturing partner supported by international quality certifications and fully committed to project delivery schedules.

Metal Fabrication & Welded Structures

Certified Steel Structures – ISO 3834-2 & EN 1090 EXC4

Quality is the cornerstone of our design and manufacturing philosophy. This commitment is reinforced by our internationally recognized mandatory certifications.

Structural Integrity Assurance
All steel structure manufacturing is carried out under EN 1090-2 EXC4. This verifies top-level fabrication capability, especially for components subjected to high dynamic loads, such as wind turbine tower elements.

Critical Welding Quality
Under the ISO 3834-2 Quality Assurance System, every welding operation (MIG/MAG, TIG) is rigorously controlled. Our certified welding engineers implement WPS/PQR procedures according to customer specifications, ensuring the weld and the heat-affected zone (HAZ) maintain full performance.

Partnering with Aldem Çelik ensures that your steel structure projects benefit from international welding expertise, certified quality, and on-schedule delivery, achieving the highest level of service excellence.
