A706 bar vs. A615 bar

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I posed the same question about relative costs to our local CRSI representative.  I have always hated using the A615 bar because it is not a very good quality steel.  I like to keep my ear to the ground when it comes to major developments in costs especially when I know that A 615 bar is not as good a quality of a steel as opposed to A 706. 


I can't wait for the day when I can eliminate A615 from a project and not worry about the economics.  Wide flange shape producers used to complain about the difference in Grade 36 vs. Grade 50 steel until Nucor Yamato steel came on line and did not charge any difference in price.  That was the over night death of Grade 36 steel shapes.  The production costs are not that big a difference.  The cost differential is in handling 2 different grades of steel, and they burden the price of the lesser specified A 706 bar. 

See Rick Rose's response to my inquiry below.  Rick is NOT on the West Coast.  The differential appears to only be about 4%.

Hi Harold,

Your question was very timely - we just had our annual fall business meting with all of our members in Chicago this week.  One of the topics was A706 vs. A615 bar.  Currently there is an average of an "upcharge" for A706 of about $20.00 per ton on top of the price of A615.  I would say that the average cost per ton for rebar is between $480 - 520/ton for A615 so the additional cost or upcharge would be very small.  I'm curious, can you tell me the basis for your question?  I look forward to hearing from you.  If you like, my local phone number is 913/351-3584.  Thank you for your interest.
