The edges of the foundation rings are protected by a surrounding protective profile.

The surrounding edge protection profile made of soft PVC has the task of protecting the upper edge of the foundation ring from impacts and damage. At the same time, it prevents scratching of the lower dome segments anchored in the foundation ring.

The edge protection profile adds a colourful accent and serves as a visual embellishment. The profile can be easily pressed over the edge by hand, it is flexible, weather, temperature and tear-resistant. The steel inlay incorporated in the profile guarantees a long service life even under the highest stresses.
