About the Manufacturer

In 1976, Wolfgang Schroeter launched a small steel fabrication business that started by manufacturing steel railings in Barrie, Ontario. Since the first wood stove rolled off the production line over 35 years ago, Wolf Steel's commitment was to be distinctive and successful in everything they do. By 1981 the demand for more had grown, and thus their Napoleon line was born. Since then, demand for Napoleon's products has extended beyond Ontario's borders and into the rest of Canada, the United States, Europe, and the United Kingdom. Napoleon is North America's largest privately owned manufacturer of quality wood and gas fireplaces, gourmet gas and charcoal grills, and outdoor living products.
