Truss is a formation produced by triangular components, in accordance with the truss bridge drawings, and coupled at joints known as nodes. The triangular units forming the truss are slim and straight in form. The truss bridges consist of a grouping of triangles that are manufactured from straight and steel bars, according to the truss bridge designs. The solid arms of the triangle are extended from the pier sides. The diagonal steel tubes project from the bottom and top of each pier, and assist in holding the arms in the correct position. Trusses are organized as straight elements that are connected at the ends by hinges to develop a secure arrangement.
