Has anyone seen this on ebay?

I'm wondering if this is good for the exterior or if it's the wrong aluminum

it will work like a champ if you can get it.

super good price. If it is indeed .019, that seems a little thin for my tastes, but someone else should chime in before you take it to heart.

I put .032 on mine, and will go to .040 on my next one

.019 is awfully thin. You would definately need some plywood under it.
But at that price it would be worth it to get them and see if they work, if not then just replace with something heavier. Good luck on your bidding and building.

if that stuff is .019 thousands thick, it would be crumpled on the floor like tissue paper..it's at least .040 thousands.



edit: fixed as per Gage's post.

I believe that would be .040. One thing to remember is that the thinner the alum, the more movement with heat & cold there will be.

Your physics handbook must be different than mine. It says the coefficient of linear expansion for all shapes/thicknesses is the same.

Gus,

Thinner sheets will distort away from the substrate more because they are more flexible at any temperature. The thicker sheets have a tendency to expand in, as you say it, in a more linear way....... different physics handbook? Get a grip man.

Hi Steve,

You came back with a reasonable answer to a "SMART A@@" comment. Sometimes the comments on the forum appear to be based upon "out of this universe" physics. I was just teasing but you came back with a good explanation. Some people have never been introduced to the concept of "linear thermal expansion" (for example a hole in a piece of steel expands when heated just the same as a piece of steel the shape/size as the hole). I find a great many car sound system enthusiasts aren't familiar with the concept of "noise pollution" either. Due to frazzeled nerves, loud sounds cause me a great deal of pain. According to my "therapists" (seen twice a week for neurofeedback therapy) I have a pretty good grip, as I haven't committed suicide (google suicide disease). I'm just having too much fun spending Suzy's money, working on my teardrop, and my other three authorized (by Suzy using "her" money) projects.

Cheers,

Gus

Well Gus, I would tell you about real world physics vs aluminum sheeting. But I've been told not to. So you skin your trailer with .016 sheeting and I'll just laugh later.
