pipe deflection Question

Hey, I'm preforming an engineering internship for the summer break and have ran into a design problem. I'm building a rack system to layer 1" solid steel bars. I need 60 1" bars per layer with multiple layers. I want to use standard black pipe for layering, and the pipe will be supported on both ends. Each individual 1" bar weighs 14lbs. The reason for wanting to use black pipe is due to weight, because the opporator will lift and hinge the pipe to get to the next layer. My concern is will 1" standard schedule 40 bend due to this weight? Keep in mind that there are two pipes assembled parallel and the 1" bars are laid across them.

Thanks

Assuming you would load the racks evenly, could you just do a simple beam deflection calculation (60x14)/2=420 lbs, evenly loaded along each bar, you can find the cross section of the pipe, and material properties, and plug them into the formula /beam_bending/beam_bending1.htm . Am I missing something??

I'm fairly new to the industry, this is actually my first related job. I'm still in school and haven't had "Strength of Materials" yet, but I did research deflection and wasn't sure if you could use the beam formula, just due to thinking of a beam as an "I-Beam". But your saying this is the right formula?

Thanks
