The thickness/diameter of the piping on the DeeZee Nerf Bars - 3" Round - Black Powder Coated Steel - Cab Length # DZ373531 is 3 inches. I went ahead and attached a diagram that shows this dimension. These nerf bars are confirmed to fit a 2021 Chevy Silverado 1500 (crew cab only).

Yes. The # DZ373531 mounts directly to the frame with the included mounting brackets. There is no drilling required for installation. I went ahead and attached a picture from the installation manual that shows the mounting process of the bars.
