Steel Plant Capacity Information
Comprehensive industry analysis is essential for making informed strategic and investment decisions in the steel sector, where market dynamics and capacity utilisation can significantly impact business success. By examining detailed plant capacity data, production capabilities and geographic distributions, organisations can better understand competitive landscapes and identify potential opportunities while avoiding the pitfalls of market oversaturation. This systematic evaluation becomes particularly crucial when considering capacity additions or acquisitions.
The global steel industry currently faces persistent challenges with overcapacity. With major producers of crude steel, flat products and long products continuing to maintain substantial capacity levels, any decisions to add new production facilities must be carefully evaluated against existing market conditions. James F King's database of approximately 4,500 steel plants worldwide provides critical insights for stakeholders to assess market concentration, regional capacity distribution and potential areas of oversupply, helping to inform more strategic capacity planning decisions that avoid exacerbating the industry's overcapacity concerns.

Other Factory Information, Steel Market Reports and Economic Appraisals
James F King offers information and consultancy advice to the steel and associated raw materials industries. Services cover the economic and commercial aspects of these industries, from mining to semi-finished and finished mill products and are generally of three types:
- regular information services for subscription clients, covering developments in markets, production potential [i.e. capacity], costs of production and prices
- annual market reviews and forecasts for major products
- special consultancy reports (including steel cost models, world cost curves etc) undertaken to clients' specifications
Mr King's capacity assessments cover most types of steel plant, including raw material preparation plants (sinter, coke, direct reduced iron and hot briquetted iron, pig iron), steelmaking (through the basic oxygen furnace or electric furnace routes), continuous casting (including slab, billet and bloom production) as well as rolling (steel sections, bar, rod, plate, hot or cold-rolled coil and coated products such as galvanised sheet) and tube. Facility data (including address and geolocation data for ~4,500 steel plants worldwide) is available for most countries, with data available from year 1990 until 2026
Market assessments cover estimates of production, which together with figures for import and export volumes (based on United Nations data), show apparent consumption calculations for most finished and semi-finished steel products (including billet and slab). These determinations are available for all countries or geographic regions for the years 1990 onwards, through to 2026, and include demand forecasts prepared to the year 2040.
