Profile rails on the front face, ball screw in the middle.

Very expensive, but very simple.
Don't waste your money is my answer.!! . . . . . What width Gantry do you want.?

Because I can tell you with 100% certainty thru building several machines with the L shape gantry using 45x90 profile that it is more than capable of handling cutting wood at 4' width and that's with using tall style gantry sides not sat direct on bearings like I do for machines mostly cutting harder materials.
On the narrower machines I've built with 700mm cutting width so 900mm wide gantry and tall style gantry sides it handles cutting aluminium no problem at lower DOC.

From KJN it's £25mtr and another bonus is the 45mm slot spacing fits the BK/BF bearing holes so easy fastening of ballscrews.

Also agree that Steel is much cheaper and I use it all the time but also see the Profile appeal for ease of building and neatness. For a wood router it works very very well and more than strong enough.
