In a hex-mesh structure (GR) as for example the type described in Patent Application Nr. 25730 A/81 by the same inventor, the shaped strib elements, which form the four sides not provided with fastening prongs (LI) for making connections, have special punched-out portions (TC) instead of a slot. The special shape's minimum moment of interdia provides reduce stiffness for the hexagonal structure and avoids the formation of gabs between the fastened portions which are difficult to fill with refractory material when installation is carried out on cylindrical surfaces having small radii, or tapered surfaces or any kind of spherical surface.
