Our mission

The mission behind all developments of Consteel is the overall reform of the way of structural design in three different aspects. These aspects encompass design methodology, software technology, and user community.


We continuously research and implement the most modern ways of steel design based on high-level, integrated numerical analysis. We are also seriously dealing with design issues outside of the standard methods in order to offer practical solutions for the engineers in these complex fields as well.


We built a highly automated calculation system with modularity and flexibility in its focus. With its help, as an engineer, you can shortcut your design process, so you can focus on planning great buildings. Seeing the changes in the software and hardware used in different engineering fields, we are committed to reconstructing the outdated workflow of structural engineering, with the support of the newest on-premise and cloud-based solutions.


We want to support a new generation of user community where the governing working rules are collaboration and knowledge sharing. Our dream is to connect demands and solutions, users and developers, models and calculations from all over the world to help a truly efficient design workflow utilizing the power of the engineering community.
