Since the beginning, Unison Hardware, Inc. has always been dedicated to providing exceptional customer service along with creatively designed door hardware. Unison began in Germany in 1991 and has since established 3 manfacturing factories in China. In 2005 Unison began developing and marketing its Inox® (residential) and Unison (commercial) product lines for the United States (North American Building Markets).

While Unison's core business in Europe has focused on OEM manufacturing for the leading brands in the EU market, in the U.S. we began developing our own brand of products and launched our product line in 2005. At the 2006 DHI tradeshow Unison launched our Inox® residential line and at the 2006 International Builders Show, we debuted our commercial line.
