REPORT

teel is both the most widely used and most recycled metal
material on earth. From stainless and high-temperature steels
Sto flat carbon products, steel's various forms and alloys offer
different properties to meet a wide range of applications. For these
reasons, as well as the metal's combination of high strength and a
relatively low production cost, steel is now used in countless products

Construction

The majority of steel goes to the construction industry. Sustainable
steel structures can be built quickly at a low price. Steel, in its various
forms and alloys, can be designed to meet the requirements of unique
projects, which allow it to be incorporated into infrastructure in all
environments. Depending on the conditions that the structure is
exposed to, steel can be alloyed or surface treated differently for
protection.

The development of efficient steel production techniques at the end of
the 20th century contributed to the growth of railways around the world
as well as the advent of the high-rise building. Many famous historical
structures, such as Empire State Building, contain steel as a primary
Steel applications can be divided into
construction material.
five sectors:
Steel can also be found in:
1. Construction
· low and high-rise buildings
2. Transport
· education and hospital buildings
· sports stadiums, stations 3. Energy
· reinforced concrete 4. Packaging
· bridge deck plates
5. Appliances and Industry
· piers and suspension cables
· harbors
· cladding and roofing
· offices
· tunnels
· security fencing
· coastal and flood defenses

Transport

Engineering steels are wrought steels that are designed to have
certain specific levels of elasticity, strength , ductility, and corrosion
resistance.
They are used in the general engineering and manufacturing sectors,
but the bulk goes to transport vehicles.
Steel accounts for over 50% the weight of an average car. Advanced
high-strength steels (AHSS) are used in vehicles. It is a lightweight
material that requires less energy to produce and reduces CO2
emissions.
Different types of steel are used for the car body, doors, engine,
gearbox, steering, suspension, wheel axles, and interior.
