Marengo Tool & Die Works was founded in 1946 as a tooling design and machine developer for the Building Channel and Metal Framing Industry, working directly with the industry’s founders. From design-and-build and testing, we expanded into full production mode for fittings, brackets, clamps, nuts, and accessories. Over the years, we have grown with multiple facilities totaling over 300,000 square feet anchored in Chicagoland as a diverse metal fabricator. Since becoming an employee owned ESOP, Marengo Tool & Die has diversified beyond its roots in the channel framing industry. Our allied products, including brackets, clamps, supports, and fittings, serve a broad range of domestic infrastructure needs such as fencing, signage, fire protection, solar, mechanical applications, electrical distribution & controls through industrial, commercial and residential applications. We proudly produce Made-in-the-USA products and material supporting our diverse and evolving economy.
