Frank Allart
Frank Allart (Frank Allart & Company Ltd) is a heritage British manufacturer of fine architectural hardware—the posh end of door, window and cabinet furniture where the finish quality and the “feel” in-hand actually matter. The business began in 1914, when George Allart started the company from a small workshop in Birmingham, and it has grown into a globally recognised name for traditionally crafted and design-led ironmongery.
Frank Allart is strongly associated with British-made brassware and decorative hardware, offering extensive ranges of door knobs and levers, pull handles, cabinet knobs and pulls, flush pulls, bolts, knockers, stops, and related fittings across a wide spread of styles and finishes.
On the corporate/history side, the company notes that after 62 years in Allart family ownership it became part of the Armac Brassfounders Group, with investment following to support the business and workforce.
