It actually came from a post on eng-tips. Promoting, selling, recruiting, coursework and thesis posting is forbidden. In Aprilthe Concrete Reinforcing Steel Institute and the Steel Manufacturers Association decided to mount a campaign to replace the initial hard metric sizes with soft. Any idea what the yield stress for reinforcing bars from that era is?

As a result, the asrm bars became identical to the original inch-sized bars, except for the markings and a small difference in strength the new metric standard calls for a stronger bar, see the table below. However, the metric markings continued to be an irritant on the job site.

Representatives of mills producing more than 80 per cent of the annual tonnage of the steel used for reinforcing bars attended the subsequent meeting of producers, distributors, and users. The sizes of the large bars are based on the square rebars formerly made.

Some mills orient the markings vertically, as in the United States, and some horizontally. The cost of producing and stocking two different sets of nearly identical sizes proved onerous. If it astmm practicable to fabricate reinforcing bars of a single grade of steel only, the inventory problem of distributors will be decidedly lightened.

Deformed bars have a higher elastic limit claimed at 50, – 65, lbs per sq in. Metric Conversion Act of The establishment of a single grade of steel for this commodity will place distributors in a position to further reduce from 33 piles to The metric size is the same dimension expressed to the nearest millimeter. Plain bars are also made, but are used only in special situations in which the bars are expected to slide for example, crossing expansion joints in highway pavement.
