TH Mining Profile

Length: It’s produced from 4 m to 18 m.
Dimensions: DIN 21530 PH-N-84042

One of the most significant advantages of TH profiles against I and H profiles is their ability to provide the 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.

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.
