Thread: D4 Landrover Bull Bar - latest news

There are various grades of aluminium alloys - some of the 'military grade' specs for armour plating are significantly more resistant to impact (I use these for my underbody plates), but I don't know if any of the commercial bar manufacturers use them, as they are considerably more expensive, and difficult to work with.

Cheers,

Gordon

Steel has a greater modulus of elasticity, it bends, aluminiun ally will crack.
When the tree hit mine it bent enough to push the guard onto the tyre. But then returned enough to clear the tyre so I could drive. Alloy bar even of the same strength would have stayed where it was.

Please don't bother

Bother with hitting a roo or with letting you know the result?

I thought about alloy (aluminium), but regardless of what the military do, we are talking about 4wd manufacturers. The steel as I understand is not that much heavier and at the end of the day - you can use thinner guage. I am balancing looks with function. I like the colour coded look personally and think the LR one is honestly pig ulgly. Something for soccer mums with Prados.
The ARB one is a really nice fit, looks good, and offers good clearance. The LR park sensors, lights, UHF antennas and winch fit seamlessly.
If you want a winch...I paid top dollar($1900) for a Warn...you can't from what I've read, fit a winch to the LR bar. I was quoted $6000 for the LR one (made by Warn as I recall).
Still - to each their own...I'm just not into bling. Just getting old I guess!CRW_7844.jpg

Gordon, the issue is not entirely material properties between aluminium and steel as it is about design. But having said that I am certain that Al bar manufacturers would use whatever alloy they can get in buk...Most probably 6106 - T6, no different steel bar manufacturers would use A360 steel plate and NB tube??? The military also have 'plastics' that give carbide tooling a touch up... that doesnt mean they get used in milk containers?

With respect to design:
Most OEM aluminium bars hug the body panels for whatever reasons.
This makes them a liability with respect to animal strike. Full stop the end. Soft malleable Al close to panel work WILL cause damage when skip comes out to say tsu tsu tsu?

Rick would know, he lives in big-badda-boom skip country. Big greays, big swampies and lots of them. I worked in Inverell for a 3 month stint. Drove Inverell Sydney return probably 5 times... 11 roo strikes. In town most vehicles were 4bys of some description. There were steel bars and then bent busted twisted ally bars... plain and simple lesson.
