Flexible application

Steel constructions can be realised and penetrating support structures, such as canopy roofs, frame system crossbars or balconies, can be reliably separated and thermal bridges thus minimised.

The Schöck Isokorb® type KST for steel constructions is comprised of the modules KSTZ for tensile force and KSTQ for transferring shear and normal forces. Quantity and layout in the construction are dictated by the size of the profiles and cross sections.

The modular design of the Schöck Isokorb® type KST ensures that it can be adapted to all profile sizes and load bearing capacity requirements.
