The world steel industry has experienced a significant transformation in the digital era. Digitalization has changed the way of production, distribution and management in this sector. One of the main developments is the application of Internet of Things (IoT) technology which enables real-time data collection. Through sensors installed on machines, companies can monitor performance, detect problems and optimize production processes. Furthermore, the use of big data allows deeper analysis of consumption patterns and market needs. This helps steel producers forecast demand and adjust production more efficiently. For example, large companies such as ArcelorMittal are starting to use analytics platforms to improve their operational efficiency. Ransomware and other cyberattacks pose a serious threat to the steel industry. Therefore, cyber security is now the main focus. Companies in this sector invest in advanced security systems to protect data and production processes. Proactive steps in cyber risk management are a must to deal with potential financial and reputational losses. Digital transformation also includes the use of blockchain technology. In steel distribution, this technology provides greater transparency in the supply chain. Every transaction can be securely tracked, enabling more efficient audits and greater trust between producers and consumers. Some companies have started implementing blockchain solutions to digitize documents and contracts, reducing bureaucracy. Additionally, the steel industry is starting to adopt automation and robotics. Robots can be used in welding processes, material movement and quality monitoring. This brings benefits in the form of increased accuracy and reduced work safety risks for employees. Implementation of automation also helps in reducing production costs and increasing output. Steel companies focused on sustainability are also leveraging digital technology to reduce their carbon footprint. Through data analysis, they can identify areas where energy efficiency can be improved and reduce greenhouse gas emissions. This initiative is not only a response to stricter regulations but also an effort to meet the expectations of consumers who are increasingly concerned about the environment. E-commerce is playing an increasingly important role in the steel industry, allowing companies to sell their products directly to consumers via online platforms. Digital marketing strategies are also becoming more important, with the use of social media and digital advertising to reach wider audiences. Human resources in the steel industry are also experiencing changes. The skills needed now focus more on information technology, data analysis and programming. Training and skills development are crucial to ensure the workforce is ready to face digital challenges. Global market visibility is increasing with digital platforms, allowing small producers to compete more fairly. With access to the same information and marketing tools, these companies can achieve a broader market share. The steel industry in the digital era not only offers challenges but also many opportunities. Adaptation to new technologies and a more sustainable approach will be key for companies to remain competitive in an ever-changing landscape. Through innovation and technology, the global steel industry can face a brighter and more efficient future.
