I have posted a couple times about this but i keep changing my mind on my racking. Now i am thinking a taller rather than wider racking system. It would be a rectangular prism about 10ft tall and 3ft wide. There will also be a shelf about every 28 inches. Now in order to solve the capacity of this i can easily look up the compression load allowed for the tubing uprights but i know the cross beams for the shelvs should strengthen it, i just don't know how to factor that in. thanks in advance!!
