metalware.ca zoominfo.com/c/metalware-corp/57640606 Metalware Corporation is a Canadian manufacturer of industrial steel shelving and storage systems, based in Montreal, Quebec, and in business since the early 1950s. The company is best known as the inventor of boltless ("No-Bolt") shelving, patented in 1954 by founders Irving and Ben Levitt — a design that became the industry standard for order-picking warehouses. Still family-owned and led by second/third-generation owners (President Mark Levitt), Metalware produces its flagship Interlok No-Bolt line, E-Series widespan shelving, multi-tier/high-bay systems, shelf-supported mezzanines, and modular drawer solutions at its Montreal plant, selling through a network of authorized distributors across North America. Its reference clients include the Government of Canada (Canada Revenue Agency, Department of National Defence), Porsche, and Walmart
