Hi-Mast Passively Safe Posts
The Hi-Mast sign support is star shaped in cross section and is made from a single
aluminium extrusion requiring minimal manufacture.
The shape not only gives the post its strength but ensures that the performance is multi-directional.
In addition, as passive sign supports are being placed increasingly in urban areas, the fact that Hi-Mast doesn’t have sharp edges or hand traps and cannot be easily climbed is an advantage.
