Mapes holds 6 individual registered patent trademarks for production of specific wires

Owned and operated by the same family since 1912, Mapes was the first company in the nation to manufacture piano wire and the first to patent the manufacturing process for piano wire.

Since then, our products have not only become the gold standard for piano wire and strings around the world but we’re also serving numerous other markets with equal credibility and excellence.
