Overhead Sign Structures
There are several types of overhead full-span sign bridge, including four-chord, tri-chord, two chord and monotube configurations.
Tri-Chord Overhead Sign Bridge
The tri-chord simple-span sign bridge is similar in basic concept to the four-chord simple-span sign structure. The notable difference between the four-chord and the tri-chord designs is that instead of having a second parallel truss to form a space frame, the tri-chord design utilizes a single chord behind the front vertical truss, which is connected with diagonals to the top and bottom chords of the truss to form the space frame. In cross section, the tri-chord space frame looks like an equilateral triangle, with the top and bottom chords of the front vertical truss forming the two vertices in the vertical plane and the back chord forming the third vertex.
Overhead sign supporting structure range from us are designed for standard and specialised signal lighting and sign applications, built to the exact specifications of your local road authority or municipalities, through various process like bending, forming, welding, hot dip galvanization and powder coating. The poles and structures can be powder coated or painted in the colour of your choice or the relevant authority’s requirements.
