Four Chord Overhead Sign Structures Bridge Galvanised Steel Lamp Posts 3m
Overhead Sign Structures
There are several types of overhead sign structures:
* Full-span sign bridge (including four-chord, tri-chord, two chord and monotube configurations)
* Cantilever sign structures
* Butterfly sign bridge
* Structure-mounted sign structures
Four-Chord Overhead Sign Bridge
The standard four-chord simple-span sign bridge consists of an all-welded or combination welded-bolted three-dimensional space frame of four chords. Diagonal members run along all four faces of the space frame with intermediate diagonals running between the front and back faces of the frame, alternatively. A camber is typically built into the space frame. The space frame is simply supported at each end by a single post, a two-column support frame, or a reinforced concrete column. It can be used for sign support (static panel or DMS), light signals or served as toll gantry.
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.
