The inconspicuous fastening method known as the plate hook or agraffen system is an approach that attaches facade panels to a horizontal rail using adjustable and invisibly mounted plate hooks. What characterizes this method are the resulting horizontal and vertical joints, which together create an expressive facade layout. The plate hooks are subtly integrated, providing a sleek and modern appearance. Prefabrication plays a key role, significantly speeding up the assembly process. This method excels with various materials such as stone, HPL, fiber cement, and ceramic, offering architects the freedom to realize creative and unique facade designs. The combination of invisible fastening and expressive joint lines results in an aesthetically refined facade with a contemporary look. The application of this system contributes to a fast and efficient construction technique that is both sustainable and visually appealing.
