Metal Selection for Rock Sliders

OK, so I've been reading up on and looking at lots of pictures of rock sliders, and I'm pretty confident about fabricating this project. My question is in the selection of metal.

The end product is an angle that fits against the rocker panel. Is it better to buy sheet goods and have a machine shop break it to the 90 degree angle, or is it better to buy angle of the right size and eliminate the break work? From experience, I know that angle is not completely uniform in it's shape, meaning, the valley of the angle has a very slight radius, as does the two opposing ends of the angle. (Basically, the angle rounds off at the ends)

Will I get a better & tighter fit with a piece of sheet broke to 90 degrees? I don't want the end product to look questionable and not fit as well as it could?

A peice of sheet broke to 90* will still have the radius. The only way to get a sharp angle is to weld together two seperate peices at 90*

Get architectural angle. It differs from structural angle in that it doesn't have the radius on the inside.

5/16 is pretty thick, but if you have it layin around....why not?

I just dug this up from search because im looking into getting angle aluminum for this and wondering if that will be strong enough. I was thinking 1/4" 6061 T6 would do the job and wanted your guys opinions. Would not be running side steps off them, just straight rocker guards.

Good to know about the arcitectural v. structural. However, could you not run a grinder on that inside edge maybe to cut down the radius a little?

The one thing I don't like about aluminum is that, it sticks to the rock.. doesn't slide like steel or plastic.

I could see that since aluminum is very gooie. i was just looking for a quick and easy route since 4x4 angle 6061 1/4" is fairly inexpensive. I would like to do a 4x6 angle A36 hot roll, but I can only get it in 5/16 which seems a little excessive, and fairly heavy

if you do it properly and run the rocker onto the subframe towards the bodymounts then the radius won't come near the bottom of the rocker panel. It sits around half an inch below it.

Hmm, if I am understanding you correctly, then you are saying to hold the angle down a bit from the edge of the rocker panel before bolting to it.
This won't work, as you loose alot of strength by relying completely on the strength of the metal around the bolts to hold the weight of the jeep on impact. Preloading the rockers and creating a physical touching connection takes the weight and distributes it across the entire panel, and the bolts are only holding the rocker in place and preventing a moment force movement (rolling under the tub). If you read A to Z fabrications install instruction, it requires a preloading of the rocker guard.

Don't know how close you are to Seattle, but http://www.onlinemetals.com/ is based out of there. Should be able to find some decent hot rolled from there, and a machine shop should be able to do a brake for cheap.

I just did mine with 1/8" hot rolled (not a lot of rocks in Wisconsin), and the local machine shop did a 90 degree for me for free. Total for the metal was $47 and change.

EDIT: http://www.onlinemetals.com/merchant...owunits=inches
4x4 1/4" hot rolled is $9.15/foot. You need about 10 feet total. Ouch.
