What Holzwerke Strunz does

Holzwerke Strunz GmbH & Co. KG is a family-owned German tonewood manufacturer founded in 1820 by Peter Strunz in the Bohemian Forest and relocated to Pocking, Bavaria after World War II. The company produces premium spruce wood components — soundboards (Resonanzböden), rib wood (Rippenholz), keyboards (Klaviatur) and inner frames — primarily for grand pianos and pianos, plus a secondary line of glued wooden components (Verleimte Kantel) for windows and doors. Customers are described as the world's leading musical-instrument manufacturers.

The company's underlying technology is the careful selection and processing of Alpine spruce from high elevations, where the wood is required to have grown evenly and matured into fine tree-ring structure. Production relies on a mix of latest manufacturing technology and manual color-sorting by qualified staff with a multi-generational 'eye and fine touch' for wood homogeneity, yielding soundboards that can withstand several thousand kilograms of string tension. Only products passing comprehensive end-of-process quality tests receive the proprietary 'Strunz Quality Seal – Made in Germany', a worldwide brand since the mid-19th century.

Holzwerke Strunz operates a direct B2B sales model under sole shareholder-managing director Thomas Hilz (since 1998). Sales are conducted via phone, email ([email protected]) and a multilingual website (DE/EN/ZH), targeting enterprise customers with customer-specific processing, custom finishing, and quote-based pricing. The company is a private German limited partnership (GmbH & Co. KG) with no disclosed institutional investors, subsidiaries, or third-party distribution channels.

Broad incumbents
