Steel-profile manufacturer at Oberriet holding 53 live VKF recognitions across its own systems and its Schüco PMS line — 21 vertical fire-rated glazing approvals, 21 glazed fire doorsets, nine VKF-TA closures, one horizontal glazing approval and one Brandschutztür. Like Forster it is a system house rather than a fabricator: the approvals cover the profile system that Swiss metalworkers build rated screens and doorsets from.
