For storm, ridge and facade clips, high up-lift resistance, the optimal fit of the clip to the tile and batten, fast assembly and protection against corrosion and deformation are the decisive quality features. Therefore, we are only using high-quality material and a clip shape that is precisely adapted to the roof tile and batten, which can then be installed in a time saving manner.
