PLate thinkness for rock sliders, .188 or .120

[legoms013]

Im going to be building rock sliders in the next month or two out of 2x2 sqaure tube but I need to order the steel now and don't know what wall thickness to get.

.120 seems on the smallish size but is light and more affordable.

.188 seems just a little too thick, and is on the heavy side (105LBs total) and over $80 per 20ft.

what is some of your guys experience with what thickness material you've used.

Depends on how you are gonna build it.

its all just going to be butt welded together with side supports for the very ends.

Personally, I would pay more to get the 3/16" (.188) over the 1/8" stuff.

1/8", I believe, is not thick enough to resist dents etc, or to not bend. 3/16" would be much stronger, and more resistant to bending.

80 bucks for 20ft is not bad at all! I remember last January, when I made my rear bumper, I used 2x6 box, and I payed $45 for just over 6 feet.

I personally wouldn't use less than 1/4" if you are using just plate. Plate isn't really that strong in the sense you are trying to use it. 3/16" will bend easily also.

I'd use 2x3" tube.

My sliders are made from 1/8" 2x3", to which I also added a length of 1" x 1/8" cold-roll steel strip on the bottom (making it 1/4" thick right at the outer edge). This saves some weight over using straight 3/16" wall tube.
So far it's held up good (the ones on my Ranger without that strip wound up getting dented up a bit).

Sorry i worded my question in the title with plate, when really I meant "wall thickness" of the tubing.

Ok so the verdict seems to be go with 3/16" wall thickness tubing and i was thinking 2"x2" to keep things small.

And to AKBronco II i made it sound like i was going to use plate/sheet steel but I'll be using box tubing of some sort.

Ok heres another question: I also want to make a replacement transfer case skid plate for the one from the factory. I have a sheet of 1/4" plate steel i could use but is that overkill? In my mind it wouldnt be, but it would be heavy.

Dependent on the design, 0.120" should be more than thick enough. How far apart are your frame supports going to be?

 

[legoms013]

I am going to just mimic the design of the factory plate while extending its length and mount the skid plate to the bottom of the frame rails with 2-3 bolts per rail.
