Sälzer

What Sälzer does

Sälzer GmbH is a German manufacturer of high-security building products headquartered in Marburg, Germany, founded in 1930 and operating as the high-security specialist within the Schüco family of companies. The company designs and produces certified windows, doors, facades, guard houses, perimeter security systems (bollards, barriers, gates), and security grilles and louvers, with protection ratings up to RC6 (burglary), FB7-NS (ballistic), and EXR5 (explosion) per DIN EN, NATO STANAG, ASTM, and VdS standards. A signature capability is combined protection: integrating multiple threat classes into a single product based on customer-specific requirements. The firm holds more than 1,000 test certificates from independent international institutes and has completed over 10,000 security projects in more than 90 countries across diplomatic, law enforcement, military, correctional, critical-infrastructure, LNG/petrochemical, financial, and private-residence verticals.

Sälzer employs 160+ staff across manufacturing, administration, assembly, and sales at its Marburg campus, which has been modernized into a Kompetenzzentrum combining production, warehouse, administration, and a customer showroom/testing facility. Revenue is generated through two streams: (1) hardware sales of high-security building components and complete solutions, and (2) professional services covering technical development, consulting, project planning, logistics, installation, and after-sales. All products are custom-engineered per threat assessment, with no public pricing; the go-to-market is direct enterprise sales supported by personal consultation, multilingual digital presence (DE/EN/FR), and reference-driven marketing.

The company is privately held, with three managing directors (Doreen Krob, Ingmar Barthel, Daniel Potthoff) listed in the commercial register. Strategic positioning leverages the Schüco parent brand for distribution while operating independently at the Marburg site, with product lines including trademarked OXIR® grilles/louvers, METAS® break-out resistant windows for correctional facilities, NATO STANAG-certified guard houses for crisis zones, and the AVIAN heartbeat detector for vehicle access screening.
