Angle bars vs flat bars stregnth

I need to put some support under a granite countertop. Instead of making actual support brackets, I want to use steel bars running across the counter extended out 10" to support a 12" over hang. Should I use angle bars or 1/2" flat bars for this?

Angle iron is always stronger than flat steel of the same thickness. Anytime you put a bend in steel it becomes stronger.

Below "rods" are what we use as a rule. The 3/4" height closely matches the thickness of the plywood underlayment.
If you are installing 3cm granite, there will be no underlayment and rods need to be recessed into top of cabinet.
Best to go over this with your installer.
