Unistrut or wood?

[smg980]

Trying to decide which would be stronger with a lesser "unloaded" weight. Looking to add sliding doors, and believe I could add them to the unistrut as others have with the wood shelving. Thoughts, ideas, etc.?

A 10' 12 gauge 1 5/8" stick will support 340 lbs uniform load.
Although most applications don't span that much with out extra support.

Here's a chart. http://www.unistrutohio.com/techtalk/unistrut-p1000.html

That chart is helpful for the unistrut, but we still don't have numbers for wood. How heavy is it spanning a 14' section, etc.

Not sure exactly what you are doing but this might help.
