TCS TWIST 6A2 is the innovative stainless steel helical bar A2 class used for anchorages, connections and dry seams and reinforced joints. The helix shape and strongly hardened steel give the bar a high strength and hardness, thus allowing a mechanical connection.
The helical bars TCS TWIST 6A2 thanks to the special shape and the strongly hardened stainless steel allow for a totally dry connection without the use of resins or mortars for installation. For the installation in the substrates to be consolidated and/or to connect, a pilot perforation must be made for the entire insertion depth.
The bar, during insertion, generates an incision similar to a thread with a constant pitch which allows the interlock of the same to the substrate. The seal of the bar to the substrate is easily verifiable by a pull test with the instrument TCS 3T Tie Twist Tester and based on the type and consistency of the substrate, of the pilot perforation size and the depth of insertion.
The helical bar TCS TWIST 6A2thanks to the special shape and therefore high adhesion is also used inside the mortar joints of the masonry. The system is called NSM (Near Surface Mounted) which is able to build a reinforced masonry.
The application of dry bars or in mortar joint is particularly suitable for preserving the exposed face of the masonry
