About Heintz Steel & Manufacturing Company
Heintz Steel & Manufacturing Company operates from a 30,000-square-foot facility on Hall Street in St. Louis, Missouri. The business was founded in 1924 by William Heintz and has remained in continuous operation for over nine decades, making it one of the area’s longest-running industrial fabricators. The shop provides custom metal fabrication including cutting, shearing, rolling, forming, and welding (MIG, TIG, and stick) on ferrous and non‑ferrous metals such as aluminum, cast iron, hardened steel, mild steel, and stainless steel. Equipment includes automatic saws, press brakes, angle rolls, plate rolls, and burning centers, all driven by CAD/CAM and computerized controllers. Welding procedures are AWS certified. Heintz serves industrial customers requiring large‑scale fabrications; the company emphasizes a “bigger is better” philosophy to handle oversized parts. Its workforce is largely trained in‑house and works under a partnership with Shopmen’s Local 518 of the International Association of Bridge, Structural and Ornamental Iron Workers.
