On-site fastening test – R-FF1 frame fixings
Installation of a ventilated facade substructure? Sounds like a challenge? Not for us and our R-FF1 frame plugs, which are perfect for such tasks, ensuring secure and durable fastening of steel elements to walls and facades. See how the on-site fastening test looks!
The installation of a ventilated facade substructure is a crucial stage that affects the durability, safety, and stability of the entire system. It requires the precise selection of fastenings capable of withstanding both static and dynamic loads, including wind forces, self-weight, and potential thermal movements of materials. The mounting elements must offer high corrosion resistance, sufficient load-bearing capacity, and compatibility with the substrate—whether concrete, brick, or steel structures. Our client chose our flagship frame fixings from our range – R-FF1 – for this task.
Universal frame fixing R-FF1 – suitable for multiple applications
The R-FF1 frame fixing is a universal fastening solution suitable for a wide range of applications, from installing window and door frames to mounting facades and structural elements made of metal and wood. Thanks to its special polyamide composition, the fixing achieves top strength parameters in various substrates in accordance with ETAG 020 (A, B, C, D), making it exceptionally versatile. Its design ensures multi-axial expansion, while the internal sleeve geometry perfectly adapts to the screw head, enhancing fastening stability. An additional advantage is the ability to create a flush installation in softer substrates such as wood. The R-FF1 fixing is a reliable and certified solution for installations in concrete, ceramic and silicate bricks, concrete blocks, and aerated concrete.
See the report from the on-site tests!
According to ETA 12/0398, the declared characteristic load capacity for fastening with the R-FF1 frame fixing in size M10 in hollow silicate and concrete ranges from 1.5 to 8.5 kN.
