Discovery TJM Bullbars

Can anyone tell me why do the TJM and ARB aluminum bullbars cost more than the steel bullbars

I'm in the market for one very soon I would think that the aluminum would be less than the steel bullbars

since aluminum is lighter than steel. I do know that aluminum can be made very strong other wise land rover bodies would bend easy which they don't I know this for a fact.

hit me up with feedback.

Harder to make and aluminum cost more in larger sizes.

Thanks Landzu very much

I really appreciate it
