The most important materials

Steel is one of the most versatile construction materials and it is also infinitely recyclable. The material steel is an iron-carbon alloy and consists mostly of iron (more than 50%). It can be hot or cold formed – thus steel is processed by rolling and forging.

Today there are over 2,500 different types of steel. The different steels are used in different areas. Particularly hard steels are used for tools and knife blades. While you need pliable steel for nibs, the steel in the concrete must be particularly tear-resistant. Tough steel is also used in the automotive sector and in mechanical engineering.

The most popular fields of application for steel are in mechanical engineering, automotive, civil engineering, bridge construction or aircraft construction.
