Weight that bars left in a bundle: If there are 75, 1-inch ring 12 feet long bars left in a bundle, the weight of the continuing to be steel is 75 bars times 32.04 pounds per bar = 2,403 pounds

Example: ¾-inch round by 4 feet (48 inches) long steel bar.0.750 inch × 0.750 inch × 0.7854 × 48 customs = 21.21 cubic inches; × 0.2833 pound per cubic customs = 6.00 pounds


Hex Bar

To uncover the area the a hex, first square the flat-to-flat distance, then multiply the by 0.866. Climate multiply by length in inch to acquire the volume. Then multiply by 0.2833 pounds per cubic customs to gain the pounds.

Example: 1-inch hex steel bar, 12 feet (144 inches) long.1 inch × 1 inch × 0.866 × 144 customs × 0.2833 lb per cubic customs = 35.33 pounds


Example 1.5-inch hex bar 3-inch long blank for chucker.1.5 inch × 1.5 customs × 0.866 × 3 customs × 0.2833 pounds every cubic customs = 1.93 pounds every 3-inch blank
