Need help chosing material for light bar

Hello, I will be mounting a 43" led light bar on top of my Commander. The bar is not big enough to cover from one siderail to the other. I will therefore have to make a 53" wide mounting bar that I can mount the light bar on to.

The light bar is about 10 kgs in weight. I'm think of using an L shaped piece of steel or alu. to make the mount. The sides of the L would be 2" and 1". They could be longer if needed.

Should I use steel or alu ?

What thickness is needed ?

I don't know the weight of your light bar, but considering those I've actually worked with, I'd choose aluminum for your mount. Square or rectangle may be a bit more rigid structurally.

Sorry, I just noticed you did have the weight in your first post. I wasn't just being lazy and not doing the math. Are there any aftermarket add ons for the roof rails that you could simply mount the lightbar to?
