The term structural steel covers a wide range of low carbon plus manganese steels used in high volume for civil, chemical and marine engineering, etc.  Many structural steels also contain small, but significant additions of other elements, such as Nb, V, Ti and Al.  These are termed High Strength Low Alloy (HSLA) or microalloyed steels.  Structural steels are produced in plate and section form and are typically used in buildings, bridges, ships, oil rigs and pipelines.

In this section, you will be prompted to think about the most important properties for a plate steel for structural applications.

You can then go on to see how these properties can be achieved.
