In this product, instead of using stirrup for bars of concrete structures for buildings and bridges, structural sheets with flexible thickness are used. In fact, instead of every 3-4 stirrups, a structural sheet is used and a rebar can be added to the center to reduce the cross section of the column and achieve the required strength. In Stirrup Surface technique, the types of rebars required in the concrete frame, such as braces, stirrups, and pins, are completely eliminated.
