Example if it was 1/2" thick - (12*.5*192)+(4*.5*192)+(4*.5*192)=5760 cubic inches
Simply imput that into the calculator or multiply by .283lb/in^3 and you get 1,633 lb. Get a friend to help you lift it /forums/images/graemlins/shocked.gif
Substitute actual thickness for the assumed 1/2".
This is a rough estimate as it doesn't take into account the rounds in the I beam.
The gentleman said it was 1/4" but that he thought it was 3/8". I will need to measure it to be sure. I need a Gantry crane beam for my garage. I guess that it would weight in somewhere between 1/2 to 3/4 of the beam weight that you gave me. Thanks for the info.
Been lurking for a while. I beam is measured by web and weight. 12x50, 10x35, etc. the web is how "tall" it is, the second is how much it weighs per foot. So the 12 x 50 would be 12" tall and 50 pounds per foot length. You might want to try this link for more information: http://www.efunda.com/math/areas/RolledSteelBeamsS.cfm.
When you order I beam it's by the height and pounds per foot generally. I was talking to my supplier yesterday pricing twelve inch at fourteen and sixteen pounds per foot. Sixty feet of sixteen pound was four hundred and twenty dollars, ouch.
Edge and wroughtn harv are very much correct in that beams are called out by height and weight. If you could give me some key dimensions I have steel design manual that I can look up the weight per foot in...
I would need the exact dimensions of the following
the height of the beam
the width of the flange
the thickness of the flange
the thickness of the web
The other option is like some one else posted you can calculated the weight of the components
Knowing the fact that a 1' x 1' x 1" thick piece of steel weighs 40.8 lbs
The flanges for example would be 4" wide and 1/4" thick for a W 12 x 14 (12" high and 14 lbs per foot length)
4"/12" x 1' long x 1/4" x 40.8 = 3.39 lbs per 1 foot length
there are 2 flanges one top and one bottom
2x3.39 lbs per 1 foot length = 6.79 lbs per foot length
The web for that same beam is 11 3/8" high and 3/16" thick
11 3/8" / 12" x 1' long x 3/16" x 40.8 = 7.25 lbs per foot length
The sum of the flanges and the web = 6.79 + 7.25 = 14.04 lbs per foot length which is close enough to 14 lbs per foot due to rounding of the decimals.
Say your beam is 10 feet long then multiply by the weight per foot
