Catari US® - Universal System
Catari US® is a multidirectional ringlock scaffolding system based on the rosette design, engineered for maximum efficiency and performance.
Each component has been optimized for functionality, weight, and load capacity, ensuring enhanced safety and long-term reliability. Exceptional versatility and load-bearing strength make it ideal for even the most complex and demanding scaffold constructions, including heavy-duty industrial and civil engineering applications.
Designed to meet the challenges of modern construction, the Catari US® ringlock scaffolding system delivers superior precision in every project.
Fit by gravity
The wedges of the ledgers fit easily by gravity, and the hole makes them easier to lift and handle during assembly.
Maximize workspace
New bridging ledger design improves ergonomics, access, and load capacity
Perfect adaptation to any angle
The swivel ledger can be easily adjusted to suit the needs of industrial projects.
Fit all configurations
With just two references, the adjustable horizontal brace covers 21 different combinations, enabling streamlined inventory management.
Efficiency on irregular façades
Redesigned with a semi-rosette, the 0.42 m and 0.73 m console brackets simplify assembly on irregular façades.
New Generation of Catari US®
Harder
Made from high-tensile steel, the scaffolding parts have enhanced structural integrity, ensuring greater resistance and durability.
Better
Redesigned with innovative shapes, such as self-locking features and swivel wedges, the system’s components make assembly easier, quicker, and safer.
Faster
Increase your team’s productivity. Lighter parts allow for quicker movement, making assembly and dismantling easier and more efficient (12%), also reducing strain and risk of injury to workers.
Stronger
With a reinforced steel structure, we have significantly increased the load capacity, allowing you to build higher and stiffer structures. Through a high-tensile type of steel, the structural integrity of the ringlock scaffolding system has been enhanced, ensuring greater resistance and durability.
Featured Components
Standards
Reinforced tube and rosette boost strength and load capacity, while the spigot and tube are now a single piece for weight optimization.
Ledgers
The expansion of the range allows for greater compatibility with all systems, including metric ones.
Decks
Different profile heights for an optimised weight.
Maximized efficiency, reduced costs
Our ringlock scaffolding system is designed for faster assembly and reduced costs. The locking wedge replaces traditional screwed connections, simplifying installation and cutting down on labour needs. With multi-purpose scaffold components, material requirements on-site decrease while utilization rates improve. Additionally, the galvanised finish and non-detachable wedges increase durability, minimizing maintenance and ensuring long-term performance. A smart solution for efficiency, versatility, and long-term savings.
Quick assembly
Catari US® features base collars that allow a single person to align the scaffold safely. Its rigid fitting and wedge blocking mechanism ensure secure linear and angled connections, quickly and without bolts or special tools. With a consistent assembly workflow, regardless of configuration, scaffolders benefit from shorter learning times and improved efficiency on-site.
Safety at every stage
Tested anchorage points provide secure harness attachment during assembly and disassembly, while guardrails every 50 cm and perimeter toe boards ensure a safer working environment. The wedge locking mechanism transforms unblocked connections into solid joints with a simple hammer blow, distributing forces efficiently for high load-bearing capacity. Additionally, Catari US® multidirectional scaffold system complies with European scaffolding standard EN 12810-1, guaranteeing rigorous external testing and reliable performance.
One scaffold, multiple applications
Since the main components of every scaffold configuration are the same, Catari US® follows just one logical assembly sequence regardless of the application. As a result, any basic assembly can be achieved just repeating few steps.
The ultimate solution for Industrial Maintenance
Catari US® is specifically designed for challenging environments, such as narrow spaces, circular tanks, and furnaces. Beyond its versatility and top-tier load capacity, the system features components specially developed for industrial applications. The foldable access deck allows for easy assembly in hard-to-reach areas while minimizing the risk of falls. The swivel ledger is engineered to offer flexibility, adjusting to any angle for precise scaffolding configurations. Combined with angular steel decks and ledgers, it ensures seamless adaptation to various industrial setups, including tanks and silos.
With its robust design and specialized features, Catari US® delivers both safety and efficiency, making it the ideal choice for industrial maintenance projects.

When on-site temporary access is required, scaffold stair towers can quickly and safely be assembled using the standard components of Catari US® ringlock scaffolding and pre-assembled aluminium stairways elements.
Download components listFreestanding scaffold
The system enables the assembly of freestanding scaffolds, offering clear, anchor-free access to formwork or wall rebars. Stability is achieved through a widened base (buttress) and, if necessary, counterweights. Its flexible bay lengths ensure full access to all key components, while adjustable widths allow for seamless integration with limited on-site space. Inner guardrails and brackets provide secure working conditions, even in cases where there is a significant gap from the wall.
