American Katerra, a steel fabrication company focused on decarbonized supply chains, is establishing its headquarters in San Antonio, Texas. The company leverages expertise from its parent, Yamaguchi Heavy Industries of Tokyo, to reduce greenhouse gas emissions across the steel supply chain while creating new jobs in advanced manufacturing.
The company's core service involves calculating and significantly reducing greenhouse gas emissions from the steel manufacturing stage through to the construction site. Utilizing advanced Building Information Modeling (BIM) software, American Katerra meticulously tracks and optimizes emissions, partnering with initiatives like EV trucking and anti-idling campaigns to achieve a greener carbon footprint for structural steel.
“We are able to calculate the greenhouse gas emissions for the entire supply chain, from manufacturing to construction,” said Milea Amanai, HR Lead at American Katerra. “Our goal is to decarbonize steel and build a greener Texas.”
San Antonio was chosen for its strategic advantages, including Texas’ zero corporate tax, a robust demographic of young, skilled talent from institutions like Alamo College District, and the region's strong ties to Japanese investment. Bilateral US-Japan investment, supported by organizations like the Japan Bank of International Cooperation, further propelled the decision.
American Katerra plans to open its first U.S. steel fabrication factory in San Antonio by 2028. This facility will focus on structural steel for AI data plants, warehouses, and commercial buildings, integrating advanced automated welding robotics alongside manual welders. The company also projects global expansion, with plans to establish operations in Pittsburgh by 2030 and later in the UK.
The company is actively recruiting for engineering, design, and welding professionals to join its growing team. It also seeks partnerships with logistics firms, construction companies, and developers committed to sustainable building solutions.
This announcement marks a significant step toward reducing carbon emissions in the construction industry while boosting local employment and strengthening US-Japan economic ties. By locating in San Antonio, American Katerra taps into a skilled workforce and favorable business climate, positioning green steel as a viable alternative for large-scale projects.
