Hot-rolled structural steels in accordance with the DIN EN 10025-2 standard are versatile steels that are used in a wide range of building and construction applications. These steels are characterized by their high strength, good formability and excellent weldability. They are offered in various delivery states and under specific rolling processes, which influence the mechanical properties of the material depending on the requirements.

Delivery conditions and rolling processes
The DIN EN 10025-2 standard specifies three main delivery conditions for hot-rolled structural steels:

Weldability and formability
Structural steels in accordance with DIN EN 10025-2 are easy to weld due to their chemical composition and mechanical properties. This makes them ideal for use in load-bearing structures where high weld seam strength is required. The steels are also characterized by their excellent formability, which means that they can be easily formed into different shapes without losing their strength and toughness.

Cold formability and hot forming
Hot-rolled structural steels can be formed both cold and hot. Cold formability is particularly important in the manufacture of components that require precise and tight tolerances, such as for bending or roll forming. These steels are also suitable for flame straightening, which is necessary when correcting deformations or adjusting components. At higher temperatures, hot forming enables simple and effective machining of larger workpieces.

Hot-dip galvanizing and surface finish
Another important feature of structural steels in accordance with DIN EN 10025-2 is their suitability for hot-dip galvanizing. This galvanizing protects the steel against corrosion and extends its service life, which is particularly advantageous in outdoor applications. The surface finish varies depending on the product form (strip, sheet or wide flat steel) and influences the choice of steel depending on the end application.

In summary, hot-rolled structural steels in accordance with DIN EN 10025-2 offer a high degree of flexibility for use in a wide range of applications where weldability, formability and corrosion protection are required. They are available in various delivery states that are specifically tailored to the mechanical requirements and processing methods.
