Iron+&+Steel

Victoria: What are the advantages of iron and steel over stone and brick?

Daniela: The develop of constructions methods in iron and steel was the most important innovation in architecture because these methods provide far stronger and taller structures with less expenditure of material than stone or brick and can produce greater unsupported spans over openings and interior or exterior designs.

Victoria: What is the importance of steel and iron after the 20th century?

Daniela: The importance of the steel and iron in the 20th century is that these materials entirely changed the concept of the wall and support.

Victoria: What are the characteristics of the steel?

Daniela: The steel is one of the strangest materials used in construction, strong in compression, tension, is elastic and workable. This material is made of iron with a touch of carbon.

Victoria: What are de disadvantage of steel and what solutions have been found?

Daniela: The disadvantages of steel are that rusts and loses strength in extremely high temperature. Normally, steel must be protected against corrosion by surface covering, but alloys such as stainless steel have developed for exposed surfaces. Aluminum and other light metal alloys have come to be favored for exterior construction because of their weather resistance.

Victoria: What is welding? What is its importance?

Daniela: Welding is a fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing coalescene. Welding is important because with this process it’s possible to reinforce materials as steel to make building bases more resistant.

Victoria: What shapes are formed with steel?

Daniela: Steel structural members are rolled in a variety of shapes, the commonest of which are plates, angles, I beams, and U-shaped channels Victoria: Are aluminum and stainless steel heavy metal alloys

Daniela: Yes, they do it.Aluminum and other light metal alloys have come to be favored for exterior construction because of their weather resistance.
