EN 10025-2 S355K2 Introduce
EN 10025-2 is an important steel standard used in the global construction industry. This standard sets out the requirements for a variety of steel products, including structural and non-structural steel. It is used by steel fabricators and manufacturers to ensure the quality of their products meet certain standards. It was first introduced by the European Committee for Standardization (CEN) in the year 1993 and is used in many countries throughout the world.
