For over 30 years, our joint research projects have resulted in the development of cutting-edge profiles being available through our structural division and the continuous development of our UltraSTEEL technology.
We have conducted significant research into the optimisation of our tooling design process – as well as developing our understanding of the acoustic and thermal properties of cold rolled steel products used in construction.
