Industry Overview
Steel Works, Blast Furnaces & Rolling & Finishing Mills
Steel Works, Blast Furnaces & Rolling & Finishing Mills (SIC 3310) anchor heavy industry by converting iron ore and scrap into slab, coil, plate, rebar, beams, pipe, and precision strip used by automakers, construction contractors, energy infrastructure builders, appliance OEMs, and machinery makers. Producers blend integrated blast furnaces with electric arc furnaces to flex capacity, while rolling and finishing lines add coatings, galvanizing, and value-added fabrication services. The sector operates under tight EPA air and water rules, OSHA safety standards, and trade remedies on imports; risks center on volatile raw material prices, carbon compliance costs, cyclical demand, and energy reliability. In 2024-2025, key trends include accelerated investments in low-emission steelmaking, wider use of scrap and DRI, digital twins for mill uptime, and reshoring-driven order books tied to public infrastructure and EV platforms.
