The team behind NSG NAKAGAWA + SAUER & CO. GMBH
Our story
NSG NAKAGAWA + SAUER & CO. GmbH was founded in Waibstadt in 1997 as an independent legal and economic entity, with the aim of developing and producing high-quality metal fibre technology solutions for the European market.
While there is a close partnership with the international Nakagawa Group, which comprises over 20 companies worldwide, NSG operates independently under its own management and has its own economic scope for action.
This independence is central to the company’s identity, shaping both its strategic direction and its daily operations.
