Steel's Applications: Buildings Take More Than a Third
Buildings and infrastructure consume 52 percent of world steel, more than mechanical equipment, automotive, and every other category combined.
Buildings & infrastructure
Rebar, structural beams, and pipe, using grades like A36 and HSLA covered on the mechanics page, the dominant use by a wide margin.
Mechanical equipment
Machinery and industrial equipment across every manufacturing sector.
Automotive
Dual-phase and advanced high-strength steels, covered on the mechanics page, for crash structures and body panels.
Metal products
Fasteners, wire, and a broad range of fabricated steel goods.
The breakdown
Because buildings and infrastructure dominate so heavily, steel demand tracks global construction activity and infrastructure investment cycles more than any other single variable, a far less technology-driven demand profile than the battery-linked growth covered on cobalt’s, nickel’s, and lithium’s own application-wise pages.
