The corrugated iron is a form to shape iron to wave-like foils, this way, it's easier to store it and transport it. Also this way it's easier to assemble it to construct simple building forms. It is very cheap and in good hands can be a fantastic material to build ceilings and lightweight structures. Throught history it has been used all around the world to fastly make structures to protect people from the enviroment, many things can be made from this material but to make stetic and good-looking things its needed the same time as used when constructing with other materials like concrete.
 * Corrugated Iron:**

To be a Iron worker is more than just knowing how to solder two pieces of iron together. Iron workers need to be in very good fisical shape and have their vision and hearing senses in perfect state, working in hights is a very dangerous activity so a good balance is essential. They need to be trained into engineer topics. They assemble every piece of the structure of the buildings from the beams to the handrails of the emergency stairs. After gathering many experiance they can be ascended to supervisors or start their own company.
 * Iron and steel workers:**

As a result to the develoment of this technich, highter and stronger buildings can be constructed. Also thanks to this material, the architecture and the urbanism made a jump to more artistical and variable structures because of its higtly malleable propierty.

 * Opinion of the quotations**

"//the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics"//

Well, that arfimation applies only to overdeveloped countries, because in other countries with less resources and money, the cast iron structures still are a way to construct, however, if we look over developed countries, I would say that the new skyscrapers where the ones that obscured the cast iron buildings instead of the new stetics because, we are talking about structures, so when a very tall building like a skyscraper is being assembled, a structure of cast iron just wont make it till the last floor.
