Tunnel Molding SystemONE of the methods used to construct buildings with a load bearing system is a concrete wall and roof. The name of the tunnel is due to the metallic form of the walls and ceilings. In the tunnel system, concrete walls and ceilings are reinforced, molded, and reinforced simultaneously. This method, while improving the speed and quality of execution, significantly improves the structural performance and seismic behavior of the structural set in terms of the integrity of their members and their connections.
