Owl Bull Bar

As far as I’m aware you can change your bumper to accommodate a new winch and winch bumper but we can’t have bullbars now in the UK
 
Bull bars have always been limited in this type of functional test. Fully welded, one-piece construction like the old ARB’s is the solution, especially with the heat exchangers hidden in the number.
I consider it an engineering problem. Think of it all like an inline fuse. Look at the design, and look at where the weak point will be when force is applied. Depending on the material, especially here in cost driven aftermarket part fabrication, a high tension fastener properly placed is likely to be stronger than a weld.
i wonder if the percpetion that the upper area was stronger is correlated to the location of the first radius bend in the tubing.
Note how the bottom straight portion did not seem deformed or bent at all, the bent part seems to be after the radiused portion of the bottom bar.
The upper bar appears to have bent also only from the radiused area and outwards and not along the long straight area.

To me, this suggests that the weakness wasn't uniform along the bar but was mainly found in the radiused areas. It makes me wonder if that is an expected behavior or if the radiused area made the steel much weaker than anticipated.
look at the thickness of the mounting plate its welded to. I would have made the plate 2x that. also the upright has no lateral dimension to it.

look at the arb pictured above, the uprights don't have those strips welded around the outside for looks. they provide lateral rigidity and resist twisting like this fella suffered. you'll also notice if you look at the arb, the outer hoops don't terminate at the top plate and get welded, the top plate has a hole in it and hoop goes thru the hole to the bottom plate, and is welded on both sides of the top plate to prevent tearing off and to provide more rigidity to the outer edge of the bumper.

You get 2x the engineering and strength for the same weight and 1/2 the price with an arb bumper. These are all just dudes with cnc/waterjets and a welder making shit they think looks good. There seldom seems to be a functional purpose to the shapes. I'm sad arb isnt making the quick and easy well engineered option for these rigs.

I think you're referring to the Toyota bumper (I assume that's the arb bumper being referred to). Yeah that is a stronger designs. It's welded to solid surface in 3 locations adds a lot of strength, particularly the one on the outer edge will make that bull bar much stronger.

I was initially confused by the mentioning of a metal strip, i thought you meant it was gusseted as a form of reinforcement but I now get that you mean the connecting tube that is welded to the outer bumper. Yes, that adds a lot of strength.
 
The bars are not for vehicle impacts...they are there to keep collisions with brush and some animals from creating vehicle killing damage. Hitting a kangaroo, a deer, a dog....brushy, grassy, tree limb encroached trails, etc. Looks like the Grenadier was going a bit faster and slammed on breaks and the nose dive caused the bar and bumper to hit the Tesla like that. I dont put guards over tail lights as they are truly force multipliers.
I have had brush bars both add on and integrated into full blown front bumpers on a couple different vehicles. Fully welded as integral unit is best.... Ineos never said that a bolt on was stronger than a full system like ARB, Demello Offroad, Expedition One, Ironman Offroad, etc.....
Never seen factory option that was MORE robust than an aftermarket version.....no matter if rock sliders, front bumpers, rear bumpers, roof racks, etc.
The same people worried about third tailights in rear, air bag operation with front impact or side impact while using heavy duty bumpers and sliders.....are the same ones that are the reason the OEM offerings and bolt on offerings are not as tough as what some want. The nannies are at fault...LOL
 
@Brock63, thanks for the heads up about Expedition One. Somehow I missed the news they had a Grenadier bumper/bullbar combo available:

I saw that exact Grenadier (the full Expedition One shop build that was on YouTube and featured on their website) at a rest stop outside of South Bend. Expedition One unloaded it through Warner Ineos (maybe they’re working on a QM or something???) and a guy from VT purchased it out there and was driving it back from Utah to Vermont. He was inside the rest stop, so I had a chance to look at it up close for a while - looked really good. Maybe he’s here on the Forum and can share his opinion - this was around May, so he’s had it a few months.

I had expedition one on previous Toyota build, love them. This bar does not have a center horizontal bar for me to mount my zombie lights, so it was axed from consideration.

If that bumper is fully welded it’s currently the only choice. Throw a light bar on your roof rack.
