Steel-profile system house at Romanshorn whose fire systems are the certified basis for doorsets and screens fabricated across Switzerland and abroad. It holds 91 live VKF recognitions — 52 for glazed fire doorsets, 19 for vertical fire-rated glazing, 16 for Brandschutztüren, three VKF-TA closures and one horizontal glazing approval. Its forster fuego light system also carries Belgian ATG approvals 3152 and 3156 at EI₁ 30 and EI₁ 60, and is the licensed basis of further EN 16034 certificates held by independent fabricators, so the profile system reaches far beyond the firms it supplies directly.
