What it takes to be an iron worker?
===Iron worker should be able to understand building plans, because this is the explanation of work to do, he should not be afraid of heights and be able to work only or in groups. ===

The iron and steel have emerged as an alternative to the construction because now not only can be used to make concrete building structures.
===Besides these materials may take different forms without putting obstacles in the design of the building and are often used as decorative elements of it. ===

To make a roller coaster using easily accessible materials such as cast iron, this is resistant to compression and is therefore used for such structures, and beams. This material welding is applied to prevent weakness in the structures.
