Energizer Park is a 22,423-seat open-air Major League Soccer stadium located in St. Louis’ Downtown West district. The project features a highly expressive structural steel frame and one of the largest canopy structures in Major League Soccer, designed to maximize weather protection while amplifying crowd energy. The primary stadium structure includes approximately 3,539 tons of structural steel, with an additional 1,799 tons supporting the long-span canopy system. Hillsdale Fabricators performed steel fabrication and erection, executing early steel procurement and complex erection sequencing to maintain schedule certainty amid pandemic-era supply chain disruptions. Precision fabrication and coordinated erection enabled the successful installation of large, heavy assemblies—some exceeding 78,000 pounds—delivering a visually striking and technically demanding stadium structure in time for St. Louis CITY SC’s inaugural season.
