What is the load capicity for a 30 foot,6 1/2 inches wide, 20 1/2 inches tall and 1/2 inches thick?
The utilitychest promise of a calculater to figure this out,but no formula.
I can help
Are you talking about a steel beam?
If so, do you know if it is 36 ksi or 50 ksi steel?
are you still there?

I don't know if it is a 36 or 50ksi, it was used in a pole shed and supported
trusses for a 80 ft wide building
I will assume a 36 ksi steel beam.The dimensions are not exact, but it is very close to a W21x50 steel beam, so I will use that.So you have trusses resting on this 30' span beam? So is it taking half of the 80' span along this beam?What city and state do you live in so I can look at possible snow load?Before we get started I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for informational purposes only (general sizing and budgeting) and is based on the information provided by you. The only loads considered for this member sizing are vertical loads, no lateral loadings were considered. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.
I don't understand the 21 by 50 , sitting on the I side it is 6 1/2 across the top and bottom and 20 1/2 from top to bottom, the beam came from a door opening I want to use it for loft storage that is 20 ft wide and 30 ft long.
It is probably closer to a W21x44 which has 6.5" wide flanges on top and bottom, it is 20.625" tall and the flanges are 0.45" thick. It weighs 44 pounds per linear foot. So this is the beam I will check.So you will have a 20' by 30' wide loft and this beam will clear span 30' across the open side?What will you be storing in the loft?
Yes thie will span 30 ft across the open side. We would like to store a collectable car at the support end and other farm parts and supplies on shelves and rows on the other areas
What does the car weigh? How will you get a car into a loft?Are these going to be solid metal parts that are very heavy? Can you give me an example of what the parts are?
The car is a 63 cutlass conv and wt is2440 on sticker, we live in the country, we would use our Cat fork truck with 16000 lk cap. The guess would 4000 more lbs, we want to use 14 in I joist on 16in centers and 3/4 blue o.s.b. for floor
I am assuming you have a W21x44 (36 ksi) steel beam spanning 30' across the open end of your 20' x 30' loft.This beam will support 1/2 of the loft (10' width by 30' long). I assumed a Live Load of 100 pounds per square foot (psf) and a Dead Load of 15 psf. I also assumed a 2,500 pound point load (car) at the center of the 30' span steel beam.With this loading condition, the assumed W21x44 steel beam will be stressed to approximately 95% of the allowable bending stress.You will need to have a local engineer size your supports, detail your connections, check the load path to your foundations and also check your floor joists.

One more thing, you need to make sure you provide solid mechanical connections between your floor joists and the 30' steel beam. This will help prevent the steel beam from moving laterally at all. Good Luck with your project!
What size should the corner I-beam on this same project be?
What do you mean by corner beam? Do you mean posts?
Yes I want to use a steel beam for the open corner
You can use a 3" diameter std. weight steel pipe A501 or A53 Grade B.You will need to use a concrete footing that is 4' by 4' and 15" deep.
