InfraBuild

InfraBuild was formed from the former OneSteel business, tracing a century of Australian steel manufacturing history. It operates as an integrated industrial company rather than an investment vehicle, producing steel long products from recycled scrap metal at electric arc furnaces. CEO Francisco Irazusta leads the executive team, while an experienced board oversees strategy, governance, and operations. The firm's core business covers three linked segments: scrap metal recycling, steel manufacturing, and downstream distribution. Key products include SENSE 600® reinforcing steel, TrenchMesh™, and structural steel for residential, commercial, and infrastructure projects. InfraBuild supplies major renewables developments such as the MacIntyre Wind Farm in Queensland, and supports large-scale infrastructure works across Australia. International operations include manufacturing facilities and scrap metal traders on multiple continents. InfraBuild employs more than 4,000 people across over 150 locations in Australia. In 2025, the firm expanded its Queensland reinforcing steel processing facilities at Hemmant and Eagle Farm to serve the state's infrastructure, housing, and Olympic construction pipeline. Its Laverton facility now runs on majority renewable electricity under a new power agreement. The company maintains industry partnerships and holds environmental product declarations for its steel products. The key structural differentiator is vertical integration: InfraBuild controls the full steel lifecycle — from scrap collection through electric arc furnace production to distribution — all in one corporate entity. This model, rare among Australian manufacturers, lets the firm track and reduce embodied carbon across the entire value chain while supplying domestic construction markets directly.
