Proangle Q is a range of aluminium, stainless steel, brass and PVC external corner profiles, designed to seal and protect corners and edges in tiled coverings. The square shape delineates the covering, avoiding an unsightly and impractical corner edge between one tile and another. Moreover, Proangle Q can be used as an edging profile for stairs, worktops, and platforms. The version with quality-certified antibacterial technology assures a 99% reduction in the build-up of dangerous bacteria and a high standard of hygiene.
