Steel is an alloy which mainly consists of iron and varying percentages of carbon. High carbon steel artefacts and weapons dating back as far as 400 BC have been found in numerous geographic locations like India and Eastern Africa. However, modern steel production, as we know it, primarily began during the 17th century in Europe.
Initially the most common approach to produce steel was by combining charcoal, iron ore and lime making use of sufficient heat to liquefy the three. The result of this is called Pig Iron, which has high levels of carbon and is hard and brittle. This was then heated again and beaten against an anvil with a hammer to remove the high levels of carbon until a stronger and more flexible product was produced, now known as mild steel. These days, air is forced through the liquid iron under extreme pressure, causing the carbon to attach itself to the oxygen and thus be removed from the iron as it passes through.
Modern day buildings, auto manufacturing, electrical goods and numerous other industries rely heavily on steel as an integral component of the production process, and have done so for many hundreds of years. The factors for this are numerous, as an example the capacity to have the ability to bend and shape steel to suite practically any imaginable requirements that modern day architectural trends might demand, or that it may be constructed on site to form the solid framework necessary to support the other great building necessity, concrete, means that it will continue to be an important component of the building and construction industry for many more years to come.
