Load carrying capacity for these Aluminum I-Beams

[DocHeb]

I am interested in the type of load/deflection these Aluminum I-Beams would be able to handle, based on the 24 foot length. I am thinking about using them for a dock ramp, so it would be just a couple people walking, no machinery-size loads.

They are described as:

"Brand new aluminum I-Beam. 24' lengths. Dimensions are 3" x 4" w/ 1/4" flange."

They may have stampings on each beam from which you could find the information you require.

They look beautiful!
I wouldn't want to guess but For non critical application they should handle that load, though people walking over water could get critical

I have 24 ft staging planks that are only like 1x4 and very light gauge, with one supported on the ends, 2 people can stand in the middle and they will deflect an inch or 2. but those beams in your pic are much heavier, if you could tie them together like a ladder is constructed, weld pcs of the same beam between the 2 runners I doubt you'd get any deflection.

You could have a nice fairly lightweight walkway.

Thanks, I didn't move fast enough and all the 24 footers were bought by one guy...
