1) We do not produce ASTM Standard Deformed Bar
2) Equivalent to 40,000 PSI, 60,000 PSI and 75,000 PSI respectively
3) Approximate. Standard requires 15% > Yield Strength
4) Absolute maximum permissible Yield Strength
Note: Measurements and weights are as specified in the relevant standard.
While every effort is made to ensure accuracy we accept no reponsability
for any errors in the above table
