because it can not erode and it is strong and will keep the building stable

Iron is rarely used in in its pure form for construction due to the ease with which it corrodes. However, it is frequently used to make steel which is then widely used on construction sites for things like girders.
By using scrap iron, you are not using iron which can be used elsewhere, like in buildings. It also saves money on sourcing and extracting new iron.
Iron 59 is used in medicine as iron suppliments for people with a lack of iron in their blood stream
Most iron is used to make steel, and steel is the most widely used metal alloy we have. Put something like 1% carbon in iron, and you get steel, which we use as a structural material in everything from the frames of glasses to vehicles to the buildings we live and work in. The world we know would cease to exist without steel.
Rust is cause by the oxidation of Iron. Basically, when Iron reacts with Oxygen, Rust is fromed. 2Fe2 + 3O2 ---> 2Fe2O3 (Rust) For this reason, it is only things made out of Iron that can rust. I hope I helped! :)
The Romans used the arch to build large buildings and bridges.
They are not. Steel girders can be used because of their strength and are easily manufactured
Irn Bru. It made in Scotland from girders, ya Ken?
Because Iron is a strong metal that is easily smelted and relatively plentiful in the earth crust.
The term is a bit misleading. Iron workers actually are construction men who erect the steel frames in large buildings and skyscrapers. Many work on steel girders very high off the ground. It is not a job for one who is scared of heights.

becos precast girders are not cast in -site and therefore faster. they also available in standard size.
iron is used by many manufacturers around the world to buil stadiums buildings etc
Usually, iron or steel is used. These metals are strong, especially steel, and iron is cheap but durable.
Iron and steel (which is made from iron) are used to make thousands of things like buildings and cars.
Iron is used for many things in our society today, like, for example, buildings, transportation, and tools.
Iron is really strong and there fore makes a good substance to use.
