Iron+&+Steel

Iron is strong in compression, but it is brittle in tension. It can be used in arch bridge, cannons and historic domes. Steel is stronger than any other material in compression and tension, although it loses strength in extremely high temperatures.  It is made of iron with a touch of carbon. It can be used in columns, beams, trusses, among others. Corrugated iron is a building material composed of sheets of hot-dip galvanised mild steel, cold-rolled to produce a linear corrugated pattern in them.  Corrugated iron is cheap, easy to transport, durable, strong, supple and available everywhere. Corrugated iron can be used for roofs and walls of houses and shops, windmills, fences, sculptures, bridges and flying sheds.  Iron workers provide quality work to meet high standards. The work can be physically and mentally demanding. Because most iron work is done on construction sites, it’s important to note that working conditions are very different from what you may have experienced in an office environment. The work environment can often be noisy, with heavy lifting machines, compressors and welding machines all working simultaneously on a job site. The work can also be physically demanding, requiring heavy lifting, along with long hours of bending, sitting, climbing, standing and crouching. But the team environment, the respectable wage and the ability to see your work in the form of buildings, bridges and other structures makes it well worth the effort.

 “//the old cast iron buildings died out. I'm not really sure whether the new skyscrapers killed them, or the new esthetics//”   In my opinion, the cast iron is not dead yet, just evolved, like everything else in life. This material is the basis of progress in technology with regard to the steel material currently used in large quantities for construction.

The architecture is much more than just **__beams__** and **__columns__**. The design of a building, in most cases, it has a meaning, for example, a **__dome__** reflects the religion, for it can be seen in most churches. The materials used for these buildings, we can convey some meaning, such as **__concrete__** transmit hardness, glass transparency and elements such as steel represents technology and progress, because it comes from old materials such as <span style="color: black; mso-fareast-font-family: 'Times New Roman'; mso-bidi-font-family: 'Courier New'; mso-ansi-language: EN-US; mso-fareast-language: ES-VE;"> **__cast iron__**. The architecture is not only done, but also felt.
