were developed at this
time?

the steel were devoleped for railroad ,bridges. etc.

Explanation:

What new uses for steel were developed during this time ? The railroad was the largest purchasers of steel and also the Mecgrmicks and Decree's farm machines helped produce larger amounts of food . The Brooklyn bridge and the first sky scraper with a steal frame were all created .

Steel is used in a wide number of applications in modern construction, including the building of railways, roads, buildings, appliances and other infrastructures. In fact, most modern structures, such as skyscrapers, stadiums, airports and bridges, are created with a durable steel skeleton.

Iron and steel are used widely in the construction of roads, railways, other infrastructure, appliances, and buildings. Most large modern structures, such as stadiums and skyscrapers, bridges, and airports, are supported by a steel skeleton. Even those with a concrete structure employ steel for reinforcing.

3rd century AD – China is commonly credited with being the first mass producers of high-quality steel. They likely used techniques similar to the Bessemer process, which was only developed and popularised in Europe in the 19th century

Steel is graded as a way of classification and is often categorized into four groups—Carbon, Alloy, Stainless, and Tool. Carbon Steels only contain trace amounts of elements besides carbon and iron.

Steel is the world's most important engineering and construction material. It is used in every aspect of our lives; in cars and construction products, refrigerators and washing machines, cargo ships and surgical scalpels. It can be recycled over and over again without loss of property.

Advantages of Steel

Speed of Construction. Structural steel enhances construction productivity because of its shop fabrication while maintaining tight construction tolerances. ...

Lower Project Costs. ...

Aesthetic Appeal. ...

High Strength. ...

Sustainable. ...

Innovative. ...

Modifiable. ...

Efficient.

A native metal is any metal that is found pure in its metallic form in nature. ... However, native metals could be found only in impractically small amounts, so while copper and iron were known well before the Copper Age and Iron Age, they did not have a large impact until smelting appeared.

If steel loses its great property of ductility and then there are more chances to increase the fractures. Some of the common disadvantages of using steel buildings are High Maintenance & Capital Cost, Susceptibility to Buckling, Fatigue and Fracture, Fireproof Treatment, Fire Damage and Fabrication Error

based on this information, i would advocate against sweatshop labour because it exploits workers in unsafe working conditions with little pay. though sweatshops produce inexpensive goods, they harm the environment, workers, and often use unsafe materials to make consumer goods.
