Weather-resistant structural steels in accordance with the DIN EN 10025-5 standard are specially developed steel grades that are characterized by their high resistance to weathering. These steels are often used in architectural projects, bridge structures and landscaping, as they are not only robust but also age in an aesthetically pleasing way. By using these weather-resistant structural steels, it is possible to dispense with additional corrosion protection measures such as coatings or paints, which saves costs in the long term.

Properties of weather-resistant structural steels
The special corrosion resistance of these steels is based on the formation of a protective patina on the surface. This patina layer is created by the influence of oxygen and moisture, which forms a dense oxide layer and protects the steel from further corrosion. This natural protection makes the steel particularly durable and environmentally friendly, as less maintenance and protective coatings are required.

Compared to conventional structural steels, weather-resistant structural steels have a higher strength and toughness, which makes them particularly suitable for use in demanding environmental conditions. They are ideal for architectural applications where the material is exposed to the weather, as well as for load-bearing structures where high mechanical loads occur.

Manufacturers and brand names
Several leading steel manufacturers offer weather-resistant structural steels under different brand names:

Applications of weather-resistant structural steels
Weather-resistant structural steels in accordance with DIN EN 10025-5 are used in a wide range of applications. They are particularly popular in bridge construction, modern architecture and mechanical engineering. Thanks to their characteristic patina, they give buildings a natural, striking appearance that blends harmoniously into the surroundings. At the same time, they offer excellent stability and durability, making them a preferred choice for projects where both aesthetics and functionality are required.

The use of weather-resistant structural steels eliminates the need for expensive protective measures, reducing construction and maintenance costs in the long term. Thanks to their versatility and high resistance, these steels are a sustainable and economical solution for demanding outdoor projects.
