Euronorm Standard List - Structural and Constructional Steels Standards: Part One

---

Introduction to European Steel Standards

The establishment of the European Economic Community (EEC) necessitated the development of standardized "European Norms" (EN) to create a unified technical language across Europe. Since 1988, a new series of mandatory European standards has been implemented to replace national standards such as BS (British Standard), DIN (German Institute for Standardization), SS (Swedish Standard), and NF (French Standard) throughout 18 Western European countries.

These EN standards encompass comprehensive specifications for delivery conditions, properties, quality, dimensions, and definitions for all products, raw materials, and processes within the iron and steel industry. The Euronorm standards cover an extensive range of structural and constructional steels, including hot and cold rolled steels, plates, sheets, strips, heat treatable steels, castings, stainless steels, heat-resistant steels, and electrical steels.

Understanding the Euronorm Designation System

For those seeking to understand how steel products are classified and designated under the European system, detailed information is available in our companion article Introduction to the Euronorm Standard Designation System.
