ASTM standard for Bar diameters > 1-3/8"

[Qshake]

All,

Is there a ASTM standard which covers bars greater than 1-3/8"? ASTM A722 covers bars only up to that dimension. Has anyone else had experience with specifying bars that are larger than the 1-3/8"?

You might want to check with Dywidag, manufaacturers of threadbar. They produce a 1-3/4" dia high strength bar for post-tensioning in the US. Occasionally use their Grade 60/400 bars for anchor bolts, but they do have high strength material specifically for PT work.

Yes, they do. But what standard does it conform to? ASTM A 722 only goes up to 1-3/8".

You might want to send email to them; a quick google search yields the following link...
