Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers uncoated, high-strength, hard-drawn steel wire for prestressed concrete tanks and similar structures. Steel samples shall be processed by either open-hearth, basic-oxygen, or electric furnace melting process. The wires shall be cold-drawn as well. Cast or heat analysis and product analysis shall be performed wherein the steel materials shall conform to the required chemical compositions of carbon, manganese, phosphorus, sulfur, and silicon. Steel specimens shall also undergo tensile tests, wrap tests, and torsion tests. Final products shall be marked by a tag.
