Steel weighs 0.2833 pound per cubic inch.
One cubic inch of steel weighs 0.283 pounds. So, a 1" square piece of steel 1 foot long weighs (1 X 1 X 12 X . 283) or about 3.4 pounds. weight in pounds.
For instance, a sheet of 30-gauge standard steel measures 0.012 inches, which is slightly smaller than 30-gauge galvanized steel at 0.0157 inches and slightly larger than 30-gauge aluminum at 0.01 inches.
Product Details. 12-gauge galvanized steel wire capable of bearing up to 150 lbs.
A 4-inch x 4-inch piece of square steel tube with a wall thickness of 0.25 inches can carry 5.41 lbs per foot of length.
Steel is the strongest common building material, making it ideal for blast resistant buildings. Hot-rolled structural steel is the most resilient, measuring roughly 50,000 psi for both tension and compression strength. Most structural steel has a compressive strength of approximately 25,000 psi.
Here is a little formula to help you remember. Take the width by the length in inches by the thickness in inches. Times that by . 2836, which is the pounds per cubic inch.
Multiply the approximate pounds per cubic foot of the material times the calculated volume of the load to get the weight of the object or load.
How do I calculate my weight load?
Load weight = weight per volume * total volume.
