3.4.1
Main Structure
The main structure principally consists of a bearing bottom structure, two sides, one top cover and
assembling-supporting components.
Bottom structure, sides and top cover are made of extruded aluminium profiles, realized according
to our design.
The signs may be considered as divided in modules, each approx 1000 mm long.
Quantity and types of assembling-supporting components depend on the number of sign modules.
Each module is supported by two mountings, each including a leg, a breakable coupling and a floor
flange. All these components are cast aluminium.
The signs are equipped with a single top cover, locked to the main structure by means of four
hexagonal knob. The main structure is matt black outside painted.
