The need typically arises in ours shops to calculation the weight of steel, whether together a component of quoting, come estimate how much steel might be needed offered a specific length that part, or to decide how hefty the bar is that we are loading into the devices for safety purposes. Counting bars in a bundle and also multiplying by weight per bar allows a fast “reality check” on even if it is or not the tag load is correct, or exactly how much weight is left in the rack.

You are watching: Weight of steel per cubic foot

Steel weighs 0.2833 pound per cubic inch. To get the weight of a stole bar, we must calculate the volume in cubic inches.

To calculation the volume, we need to very first calculate the area in square customs of the section, then multiply through its length.

Square or flat Bar

To discover the area that a square or flat bar, multiply the broad by the thickness. Climate multiply the by the size (in inches) to calculation the volume, then multiply the volume by 0.2833 lb per cubic inch.


Example: 1-inch square steel bar 12 feet (144 inches) long.1 inch × 1 customs × 144 inch = 144 cubic inches ; times 0.2833 pounds per cubic customs = 40.97 pounds

Example: ½ customs × 2 inch flat 10 feet (120 inches) long.½ inch × 2 customs × 120 customs = 120 cubic inches; times 0.2833 pound per cubic inch = 33.99 pounds


Round Bar

To find the area that a ring bar, square the diameter and multiply by 0.7854. Multiply this through the length to calculate the volume.

Example: 1-inch ring by 12 feet long steel bar.1 inch × 1 inch × 0.7854 = 0.7854 square customs × 144 customs = 113.09 cubic inches; × 0.2833 lb per cubic inch = 32.04 pounds every bar


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

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


Hex Bar

To uncover the area the a hex, first square the flat-to-flat distance, climate multiply that by 0.866. Climate multiply by size in inches to get the volume. Climate multiply by 0.2833 pounds every cubic inch to obtain the pounds.

Example: 1-inch hex stole bar, 12 feet (144 inches) long.1 customs × 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 inch × 0.2833 pounds every cubic customs = 1.93 pounds per 3-inch blank
