Top USA and International Steel Manufacturers

Welcome to the guide to the top US steel companies and global steel manufacturers. Steel is a versatile metal that is used in construction and as a core material for the manufacturing of a large range of products for commercial or consumer use. Prized for its strength, durability, and capability to be recaptured and recycled, steel is an alloy of iron and carbon, and is able to be produced in different grades by the addition of other elements such as nickel and chromium, as in the case of stainless steel.

Types of Steel Suppliers

Suppliers of steel may be characterized by the specific end products produced and the processes employed. These generally fall into 2 separate categories:

  • Steel Service Centers

These companies represent domestic sources of steel that offer formed steel products in usable form factors and dimensions that can then be further processed into finished steel goods such as appliance housings or steel roofing using manufacturing techniques such as roll-forming. Examples of standard form factors include beams, bars, sheets, coils, plates, pipes, and wire.

  • Global Steel Manufacturers

These global companies process raw materials such as iron ore and carbon using blast furnaces and converters, and whose output is continuously cast steel in the form of ingots, and semi-finished products such as billets, blooms, and slabs, as well as liquid steel for castings. These companies are located world-wide and while some are publicly traded, many are state-owned in countries such as China or India. They also may produce standard products as steel forms suitable for sale and subsequent processing and machining into finished goods.

We've evaluated companies in both of these categories below:

US Steel Companies

Domestic manufacturing companies in the USA of steel stock, or steel service centers, offer steel raw material stock in standardized form factors and dimensions that can be used to create finished steel products through fabrication processes such as roll-forming, cutting, galvanizing, or welding.

Standard material forms available from suppliers of steel include beams, bars, sheets, coils, rods and tubular profiles, plates, pipes, and wire. Different alloys of steel are also available with varying chemical compositions and mechanical properties, which also impact the environmental and operating conditions for which the alloy is best suited.

In Table 1, below, we've outlined steel suppliers/service centers in the USA. The companies shown are selected from suppliers as found on, based on user session data from 2018.
