Which countries are the largest producers of I-beams?

China is the top producer, manufacturing 50% of global I-beams via mills like Baosteel and Hebei Iron & Steel. Its dominance stems from low labor costs and massive domestic demand (construction, infrastructure). The U.S. (Nucor, U.S. Steel) is second, producing 15% with a focus on high-strength grades. Europe (ArcelorMittal) accounts for 12%, specializing in weathering and cold-formed I-beams. India (Tata Steel) is growing rapidly, with 8% global share, driven by government infrastructure spending. These producers supply regional markets, with China exporting 20% of its output to Southeast Asia and Africa.
