K profiles are widely used in underground mines and railroad/highway tunnels, providing not only a higher resistance but also a yielding support to stabilize the underground cavities.
One of the most significant advantages of K profiles against I and H profiles is their ability to provide same high tensile momentum on both cross sections (X-X and Y-Y) throughout the profile. Besides the ease of assembly, dismantling and high performance at the junctions; they maintain full support during the decreasing cross section of the underground cavity by sliding on each other without major deformation.
In our production facilities, K profiles can be supplied as hot rolled bars of various lengths according to customer demand or as final products prepared according to usage area.
