Industries Steel Tailored Engineering Solutions for Steel Industry Challenges Everything engineered for a stronger, more sustainable steel industry Engineering the Future of Steel The steel industry is evolving, with green steel, hydrogen-based production, and Direct Reduced Iron (DRI) processes shaping the next generation of steelmaking. Major industry players—including Fortescue, BlueScope, Rio Tinto, and BHP—are leading the charge with DRI pilot plants, Electric Arc Furnace (EAF) technology, and new processing facilities in Western Australia. Soto has been part of this industry’s transformation from the beginning, with its first major project being refractory engineering for the now-defunct HBI plant in Port Hedland. As Australia prepares for the revival of HBI and the shift to low-emission steel, Soto continues to provide engineering solutions that improve efficiency, safety, and environmental performance. With expertise in mechanical, structural, and pipework engineering, Soto supports both traditional and emerging steel production methods, ensuring projects are engineered for reliability, performance, and sustainability.
