As per EN 10025-2, steel can be ordered either +AR as rolled or +N normalized rolling.
So as a designer how do you specify whether +AR or +N is required?
Since we are only concerned with mechanical properties of steel grade as specified in the code for design.
Please see my interpretation & correct if I am wrong,
As normalized rolling is used to improve the mechanical properties of steel
We shall specify grade like S275 J2 as per design requirement,
then steel supplier is suppose to decide whether he is capable of achieving the mechanical properties of steel in as rolled condition or not.
and accordingly he will supply +AR or +N grade.
Am I right?

Suspension of the upper edge of the walls with the earth reduces the displacements responsible for all the stresses that develop on the structural carrier.
The patent is stacked into the ground to draw from it a force that transfers it to the upper end of the wall in order to apply a counterbalance to the torque of the wall
