US® is a modular system consisting, in terms of structure, of vertical (standards) and horizontal (ledgers and transoms) elements and diagonal braces, combined to form a steel truss.


With a simple hammer blow positive connection are transformed into a non-positive one - wedge locking mechanism. Moreover, once the end of the wedge head matches the radius of the standard, forces are transmitted centrally onto the standard over a wide area, assuring solid and high load-bearing capacity joints.

The US® Scaffold is manufactured using high-strength steel, mechanically welded and coated with a hot dip galvanization, which offers to the user the highest product quality and durability with the least possible maintenance.


The rosette geometry with two sizes of holes allows a wide-ranging combination of angles between ledgers. This, along with the range of accessories available and the high load-bearing capacity of joints, permit a wide array of layouts and an unmatched range of uses: simple facades, complex industrial structures, sophisticated supporting structures, access or working towers. Variable spacing for the standards and transoms ensure that the design of the scaffolding

Its design is based on the ring-lock fitting - rosette - and is meant for the most complex and demanding scaffolding constructions.


The rigid fitting and wedge locking system, fast and non-bolted, ensure automatically right-angled connections, linear or angled, and waiver special assembly tools. The assembly of the system is self-explanatory and can be complied in safety by regular scaffolding crews.

The rosette is an eight holes disk welded to the standards every fifty centimetres that can accommodate up to eight connections of combined ledgers, transoms or braces, by a wedge locking mechanism.


Once the ring-lock fitting uses a squeezing wedge, in replace of the time consuming screwed connections of conventional scaffolding, the assembly process is simple and reduces, thereby, the manpower needs. In addition, as with the same components numerous other applications are possible, on- -site material requirements are automatically reduced and utilization rates are increased.
