Trusted Partner to the Iron & Steel Industry
For more than 35 years, IAC has been a trusted engineering, procurement, and construction (EPC) partner to the global iron and steel industry. From traditional blast furnaces and basic oxygen furnaces to modern electric arc furnaces (EAF) and emerging direct reduced iron (DRI) technologies, our team delivers integrated solutions that improve reliability, maximize throughput, and ensure compliance.
Steelmakers face increasing pressure to balance efficiency with environmental responsibility. IAC supports this transition with expertise in dust collection, emissions control, material handling, and thermal processing systems—critical to both established operations and the next generation of low-carbon steelmaking. Our proven track record includes some of the largest baghouse and ventilation projects in North America, as well as turnkey EPC support for greenfield steel plants and expansions.
As the industry advances toward green steel powered by hydrogen and renewable energy, IAC’s vertically integrated capabilities—engineering, OEM equipment, construction, and lifecycle services—position us to help steel producers meet their production goals while reducing environmental impact.
Industry Challenges
Iron and steel production operates under some of the harshest industrial conditions, requiring robust solutions that balance throughput with compliance and sustainability. Producers face several key challenges:
- Air Emissions Compliance
Steelmaking processes generate large volumes of high-temperature gas and dust from electric arc furnaces (EAF), basic oxygen furnaces (BOF), and casting operations. Facilities must meet increasingly strict EPA and global environmental standards for particulate matter, SOx, NOx, and hazardous air pollutants. - High-Volume Dust Collection
Capturing fugitive emissions from EAFs, ladle metallurgy furnaces (LMFs), and continuous casters requires large-scale ventilation systems, baghouses exceeding one million acfm, and advanced ductwork designs. - Byproduct and Slag Handling
Safe, efficient conveying and storage of steelmaking byproducts—EAF dust, slag, and alloy additives—are critical for plant reliability and downstream material recovery. - Operational Reliability in Extreme Conditions
Equipment must withstand abrasive materials, thermal cycling, and corrosive gases while maintaining uptime to support nonstop production schedules. - Decarbonization Pressures
The steel industry is under global pressure to decarbonize. Transitioning from coal-based processes to hydrogen-rich direct reduced iron (DRI) and renewable-powered electric arc furnaces is reshaping capital projects and technology adoption.
IAC’s systems and lifecycle services are engineered to address these operational and environmental challenges, helping steelmakers achieve performance targets while preparing for the future of green steel.
