ETA certificate for Forte rope tension parts
The rope tension parts in our Forte product line have been awarded the ETA seal of approval. This certifies the tensile limit values of our Forte components.
Our Forte product line combines stainless steel ropes and tension rod systems. This creates a wide range of combinable components with standardized dimensions. The Premium line enables architectural solutions that can withstand high forces and have a filigree design.
The rope tension parts in our Forte product line are now available with the ETA (European Technical Assessment) seal of quality. The ETA certification includes our Forte clevis (M12 – M36), swaged and installed with turnbuckle, and our Forte external threads (M12 – M36).
With the documented limit values, architects, designers and structural engineers can use our certified Forte products throughout Europe.
Quality and tested production
The tension ropes and rods in the Forte range allow the use of small diameters that can also bear high forces over the desired spans. In order to achieve this balance between finesse and strength, the components of the Forte product line are subject to high quality and durability requirements.
All Forte fittings are milled from high-quality stainless steel. Their construction and one-piece manufacture give them the necessary robustness. The precise CNC production also enables uniform dimensions across all components in the product line. This makes them freely combinable and simplifies construction planning.
The manufacture of our Forte products is regularly monitored by independent experts. In combination with rope nets, our Forte products are approved by the building authorities. The new ETA 21/0536 certification covers our Forte rope tension parts (without rod tension parts).
Services support every step
To provide the best possible support to users of Forte solutions, Jakob Rope Systems also provides services to complement the product line. Even at the planning stage, and when selecting the correct components, Jakob product specialists are already available to assist. Users can also access the know-how of Jakob for detailed specification support and requirements for anchor points and connecting components.
Jakob will then use the Forte components selected by the customer to manufacture the complete system, where all Forte elements are adapted to the required dimensions and acting tensile forces. Once Forte solutions are installed, regular inspection and monitoring is appropriate for some projects. This is also covered by the service offering of the Jakob product line. This provides customers with detailed measurement data regarding the forces acting on the structure and the condition of the construction project implemented using Forte.
Himmelhausmattesteg Trubschachen (Switzerland). Suspension bridge with rope nets as substitutes for suspension ropes. Supporting ropes Ø 26 mm, tension rods M36 and Forte.
For the lightweight construction of a suspension bridge in Emmental, Forte tension elements provide a slender structure and exceptional stainless steel design. The high-quality material effortlessly resists the fluctuating climatic influences over a long service life. The ropes and rods installed here demonstrate the versatility of the Forte product line.
Hanging gardens, Station Courtyards in Aarau (Switzerland). Hanging gardens, Station Courtyards in Aarau (Switzerland). Horizontal suspension ropes Ø 14 mm with Forte M24.
Forte is already well-proven in green planting installations across numerous projects. Here, designed as elegant suspension rope systems, the tension elements span outdoor courtyards and internal building atria. Forte is used to bear substantial tensile loads, working elegantly as a structural element in the background. This allows the green plants to come to the fore.
Ibex enclosure, Dählhölzli Bern (Switzerland). Support ropes with Forte M16 – M26 and toggles.
In the Dählhölzli wildlife enclosure in Bern, Forte systems support Webnet structures made of slender elements across various span widths. This gives the wildlife enclosure a transparent look, with a clear view of the animals and their surroundings. The supporting elements blend elegantly into the background here too. The Forte components provide a robust yet open construction, avoiding the need to use solid materials.
Goodwood Festival, Westhampnett (UK). Tensegrity structure. Rope Ø 6 – 26 mm, Forte M12 – M36.
A Tensegrity installation in Great Britain utilizes Forte to create a design of ropes and rods which really uses the potential of the material and the engineering to full effect. The Forte tension elements used here were manufactured by Jakob Rope Systems for the installation in such a way that the sculpture is self-supporting and balanced. Forte allows this installation to float.
