Formulas for weight

admin

I was hoping to see a sticky for this, but can somebody please post the formulas to figure weight for steel in angle, plate, and beam form. I'm having trouble finding the formulas with Internet searches.
Reply:usually steel supplier will list weight per foot.for example channel might be 8" x 11.5 (11.5 ponds per foot).or 2x2x3/16 angle listed as 2.44 lbs per foot.or try google. only took 2 seconds to type it in.https://www.google.com/search?q=stee...utf-8&oe=utf-8
Reply:Yes, however I need to be able to calculate the weight on my own (and show the math) for a class I'm taking. I have been searching for the formulas (I saw them once but can't find them again) on line and have only found charts and online calculators similar to what you posted. Thank you for your help though. I don't even see them in the Procedures Handbook.

Reply:Unless the professor needs it right down the 1/2 oz, what's been posted will get you in the ball park. Things like channel, angle, I-beam and H-beam will be a little tricky due to the radii where the flange and web meet and the taper on flanges. I'm sure there's formulas out there but a table of weights would sure help.                                    MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
Reply:Just get a steel catalog. It has all the shapes as well as what they weigh per foot.
Reply:If you take length of all sides ,add together ,times by length of piece will give area.Times this buy weight per unit( square foot,square meter ) .Rember to subtract thickness of steel from one adjoining side(example 8x8x3/8 angle,one side would be8" the other would be 7 5/8 "total 15 5/8).This should get you real close
Reply:I do it ALL THE TIME. So much quicker than looking at a steel catalogIn inches:for rectangular parts: LxWxH= then x .283Cylinders: pi x radius squared x height= then x .283substitute .283 for .098 if it's aluminum-DoogieMiller 350PMiller Trailblazer 325 EFI w/ Excel PowerLincoln LN25 suitcase welderXMT 304/22a feederMiller Syncrowave 350LXMiller EconotigHobart Handler 140(2) Uni-Hydro 42-14Hypertherm 65 plasmaWEBB Gap bed lathe
