Here is an interesting research list of the top 40 Steel Producers and manufacturers globally based on the last year from 2007 approx. The growth of Russian & Chinese producers continues but still the strong management team at ArcelorMittal  and Nippon hold there top two positions.

With Thanks to the Top-40 producers by International Iron & Steel Institute

This is a useful datalist of the largest steel-producing companies in the world as listed by   the International Iron and Steel Institute. The list is compiled from its page Top Steel Producers 2007. Note that not all steel is the same, some steel is far more financially valuable than other steel.

Over the coming months we intend to help buyers learn more about what is happening in the great world of Steel manufacturing and the many commercial applications that high quality steels can be used.

To provide an accurate database of the best steel wholesalers and manufacturers in each steel sub sector covering Mild steel, Stainless steel and other mixed steel materials.

The Use of Steel in the modern world

Steel has probably the widest range of applications of any material. The wide range of alloy compositions, mechanical properties and product forms available make it a versatile material that is used in components and products that may be small or large, high-tech or low-tech, everyday or specialist.

Here is just a small selection of its uses, of which many are found in our everyday life:
Home building, Domestic appliances such as fridges, washing machines, ovens and microwaves, sinks, radiators, cutlery, hi-fi equipment, razors, pins.

Food and beverage cans, aerosols, paint and chemical containers, bottle tops and caps.
Travel and Transport,Car bodies, engine components, wheels, axles, trucks, transmissions, trains, rails, ships, anchor chains, aircraft undercarriages, jet engines components.
Construction
Low and high rise buildings, housing, modular buildings, retail, industrial, education and hospital buildings, sports stadia, stations, reinforcing bars for concrete, bridge deck plates, piers and suspension cables, harbours, cladding and roofing, office, tunnels, security, coastal and flood defences.
Power and energy     Oil and gas wells and platforms, pipelines, electricity power turbine components, electricity pylons, wind turbines.
Electrical and Magnetic, Electromagnets, transformer cores, electromagnetic shields.

Earth-moving and quarrying equipment, cranes, fork-lift trucks.
Agriculture and Industry     Farm vehicles and machinery, storage tanks, tools, structures, walkways, protective equipment.

In short, nothing is manufactured, processed or transported without steel.
