The profile line is suitable for protecting the outer edge of tiling and smoothing over hard edges, and the self-adhesive version is effective for hiding tile damage caused at a later date. For places with heavier industrial traffic, where edges are frequently exposed to knocks, copper and stainless steel profiles are recommended over aluminium, while in, for instance, children’s playhouses, schools, kindergartens, the security plastic corner edge guard is suggested because it absorbs impacts.
