Update, Valmont answered:
“Valmont S-25 material has the same mechanical properties as ASTM A572 Gr.65, with the exception that the maximum yield is 90ksi and the maximum tensile is 100ksi. It also requires charpy tests on a per plate frequency.”
The for PLSPOLE modelling purposes S22 = S25
Thank you, but I'm sure is not japanese steel, what happens is that Valmont has the tendency to rename standard ASTM materials with a number of its own, and in their drawings they refer to the materials using that number.
I know for example that Valmont's S-22 is actually ASTM A572 Grade 65...
I cannot think in an easy way, but what I would do is offset 20ft or so one of the lines so they don't overlap when you merge them, import/merge both DON files, and then using swap "translate" the cables structures by structure from the offset line to the other. Of course you would need to be...
ASTM A563 requires:
Hex Nut Grade A for A394 T0
Hex Nut Grade DH for A394 T1
"Regular" Hex nuts grade DH are not hard to find for suppliers of A394 bolts.
