A deployable truss that extends and retracts in a stable and synchronous manner, and can deploy integral folding panels. Primary orthogonal joints, each consisting of two hinged halves, connect rotationally to the truss diagonals with an angled fitting. The main hinge pin of the orthogonal joints remains orthogonal to the truss longitudinal axis and remains centered in the folding truss diagonals. Hinge pins of each truss joint are connected by center-folding chords which cause the truss joints of adjacent bays to remain parallel to each other. Folding diagonals connected to the primary joint halves are hinged together, permitting the diagonals on each side of the truss to remain parallel to each as they form the short sides of a rectangular truss. The truss may deploy z-folded panels with active surfaces such as photovoltaic, reflective, heat-radiating, LCD/plasma, or radar; or structural floor panels for folding work platforms, bridges, and walkways.
