Schweiter Technologies AG, a Swiss group headquartered in Steinhausen and founded in 1912, specializes in the development, manufacture and commercialization of composite materials and solutions for lightweight construction through its core division 3A Composites; the division produces extruded and cast plastic and lightweight panels, aluminum composite panels for high-quality facades, and core materials based on balsa wood and PET foam, serving the display, architecture, wind energy, marine, transportation and industrial markets with well-known brands including Airex, Alucobond, Baltek, Dibond, Forex, Gator, Kapa, Perspex and Sintra. The company operates globally with approximately 4,200 employees, generating the majority of revenue from Europe alongside significant presence in the Americas and Asia. In July 2025, Schweiter Technologies divests its non-core Bus & Rail business unit to a financial investor, sharpening its strategic focus on core composites activities amid a transition toward higher profitability as reflected in its 2024 annual and 2025 half-year results.
