Maria Medina: hi guys Ana Piñango: Hi Maria Gabriela franklinloaizag: Hello Ana Piñango: hello Franklin Maria Medina: so tell me do you guys read about iron and steel as material for construction? Ana Piñango: Yes, it was very interesting Maria Medina: hahaha yes Maria Medina: could you tell me What are the advantages of iron and steel over stone and brick? franklinloaizag: Yes, I did, It´s unbelievable all the advantages this materials bring with them Ana Piñango: Yes, I Could. Ana Piñango: Cast iron was used in brige buildings and is resistent to fire and corrosion. And steel is more uniformly strong, elastic, workable and it is high resistance in all stresses It is ability to bear loads and to be produced in an endless variety of forms Maria Medina: great Ana Piñango: franklinloaizag: I read there was a change in construction in the 20th century because of these materials, do you know something about it and about their importance in the moment? Ana Piñango: yes, The evolution of steel frame construction in the 20th century entirely changed the concept of the wall and the support and made it possible to produced fused joints with less labor and material Maria Medina: good Maria Medina: well I read about some characteristics of steel like that it provide far stronger and taller structures with less expenditure of material and can produce greater unsupported spans over openings and interior or exterior spaces. is more uniformly strong, elastic, and workable, and its high resistance in all stresses (tension, compression and bending) can be closely calculated. Maria Medina: in australia corrugated steel was commonly used in the houses construction because of its cost and easy transportation Ana Piñango: Nice answer Ana Piñango: Maria Medina: but as long as steel have all this great characterictics it also have some problems. 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. franklinloaizag: Nice Ana Piñango: Good franklinloaizag: This are excellent material but what made them even better to work with was the creation of weldings Maria Medina: oh really? franklinloaizag: it consists in joining together the pieces of steel by melting them and creates a stronger and rigid structure which joints are as firm as the member and wich distributes the stresses between beams and columns Ana Piñango: I didnt know it.But now I know jeje Maria Medina: hahahaha Maria Medina: thank you franklin franklinloaizag: there are different shapes mades of steel developed to create stronger structures, some of them are: angles, I beams and U shaped channels franklinloaizag: It´s amazing how usefull iron and steel could be franklinloaizag: I believe they are the best materials ever Maria Medina: i have one more question Maria Medina: Are aluminum and stainless steel heavy metal alloys Maria Medina: ? Ana Piñango: ?? franklinloaizag: no, they are not Maria Medina: yes I though that Maria Medina: too franklinloaizag: they are light metal alloys Ana Piñango: me too. Ana Piñango: I agree with you Ana Piñango: Well Ana Piñango: .... Ana Piñango: guys franklinloaizag: they have come to be favored for exterior construction because of their weather resistance Maria Medina: exactly franklinloaizag: It was very productive to have had this chat with you, I've learn a lot Maria Medina: well guys I really leran about steel and iron than you for sharing this chat with me Maria Medina: i agree with you franklin Maria Medina: I´ll see you in next chat byee Ana Piñango: guyss have a good day!! Ana Piñango: franklinloaizag: Good bye I hope we can chat together soon Maria Medina: Happy birthday ana!! franklinloaizag: btw happy birthday ana!! franklinloaizag: nice day1 Ana Piñango: Thanksss Ana Piñango: hahahaha
