An EN Steel standard is a European standard or euro norm that specifies the requirements for a product or process. Generally EN Steel standards apply when working in the EU, when working for an EU company (directly or indirectly).

​

For each steel standard the first two letters EN denote that it is a European Steel standard, the number after that is the standard number. The next number is the part of the standard.

​

This standard covers the common requirements for all types of structural steel plate. These steels have much smaller grains than the standard structural steels making them somewhat stronger.
