One roll-forming line in Europe. 480 buildings later

TheoSteel did not begin as a conventional construction company.

It began in Ankara with a single advanced roll-forming line and a clear ambition: to rethink how light steel structures are engineered and manufactured by bringing precision engineering, digital technologies, and controlled production together.

We had seen how even well-designed steel structures could be affected by inconsistencies in on-site production and assembly. Our response was to build an integrated system in which engineering and manufacturing are connected from the very beginning.

At the heart of this system is TEOCAD, our digital engineering software. It enables structural designs, engineering data, and production information to be developed, coordinated, and prepared within a fully digital workflow.

That data then moves directly into TEOTECH roll-forming technologies, transforming digital engineering into precisely manufactured steel components. By connecting design with automated production, we maintain greater control over dimensions, consistency, and manufacturing quality throughout the process.

From our first roll-forming line to 480 structures, this approach has evolved into an integrated engineering and manufacturing capability serving projects across different markets.

Today, TheoSteel has extended this journey to Bulgaria, establishing a European base from which we continue to develop and deliver light steel technologies and solutions for international markets.

Our manufacturing infrastructure provides a monthly production capacity of up to 4,500 m², supporting residential, commercial, and industrial applications while maintaining the precision and efficiency built into our system.

Our journey has expanded across borders, but our principle remains the same:

Better buildings begin with better control.

By combining digital engineering, advanced roll-forming technology, and factory-controlled manufacturing, TheoSteel connects the digital model to the physical structure — delivering light steel solutions engineered for precision, efficiency, and long-term performance.
