Aluminum tubing strength
Aluminum tubing strength
(OP)
I am wanting to manufacture a prototype aluminum ladder. A ladder we currently manufacture uses 1.750 x .750 x .125 6005 T5 channel. I would like to use a 1.750 x .750 x ? 6005 T5 rectangular tube. My question is, what wall thickness can I use on the tubing that would match the strength of the .0625 wall thickness of the channel? Thank you very much in advance for any replies.

There are also ANSI standards for various kinds of ladders.

Second - if you change from a channel to a tube keeping the width, depth and thickness the same, then the tube will be stronger.
Third - if you halve the thickness but double the quantity, the strength will in theory be the same. You will have to review the thinner sections for web cripling, shear and local buckling.
Fourth - for a small item as this, go with the same thickness but a tube. The couple of dollars won't really matter unless you are making a lot of them. Welding the rungs will be easier in thicker material. When human life or safety is at risk, don't even think of skimping.
