I wouldn't use that stuff got to many . . . It's.!!

It's light duty thin wall stuff.
It's too narrow in middle with potential to twist.
It doesn't provide ideal or easy rail fastening because slots are in wrong places.
It will fill with and collect chips if plan is to face forwards, (say this because of your simple Z plate ref.?)
It won't allow for simple Z plate if rear facing has the top of channel restricts access to ballscrew so placing ballnut bracket further back than needed.
It's not going to provide anything extra the L shape does.
It's going to cost 3 times the price of L shape.
It's going to be weaker than L shape has it's thin walled and narrower.

Bottom line is It's inferior and 3 x the price.!!! . . So why bother.!
