Is this unit solid built, I mean metal of some type or just palstic outside the unit?

Outer parts are made of plastic. My opinion, this unit can not withstand the slightest jar. I accidently bumped the disc tray while reloading and it would not retract. Might be a waste of your money.

I like component very much, because of metal construction. The thick glass shelves should have no problem to holding as much weight. I have a few heavy equipment there, unit is stable.

I not using on rail so i can't answer your question. However, if you are looking for solid piece, you might want to look somewhere else.

It's not as thick a piece, but it's solid, welded at the mounting points. I love mine.

Not sure - don't think it is solid, but it is very sturdy. We are pleased with it

Everything appears to be metal. I was cautious about plastic units breaking, which is why I went with this one. So far, it has held up really well, and is very sturdy (and heavy). I could probably use it as a weapon in a pinch. :)

It is made of heavy duty plastic, so the unit itself would be fine for outdoor use, providing you have a wall or surface that you can mount it on.

I don't believe the unit is solid. I bought it for my Grandmother. I installed it into a stud and she used it daily and it had no issues holding her weight as needed.

I don't know, but it's very solid and works great. (Is there a way to tell?)

No the back is solid. I just ended up leaving the back off of mine and its worked just fine.

It has two removable shelves inside, and two towel racks outside. Very solid unit.

Yes, it is. The unit is quite solid and hea y. Nicely finished on one side, the other side being a little rougher.

Metal. Considering how comparatively low priced this product is, it is of comparatively high quality. I installed it in a matter of minutes and have had it in service now for several months with no complaints.

I don't know if it's solid wood throughout but it is very well built! We have been very happy with it.

It appears to be solid, it's a brushed finish and has some heft to it. I'm satisfied with it's design and use.

It's metal, feels more solid than aluminum but not sure. It's a quality piece.

thin metal. it's relatively light (guessing less than 5 pounds) so it shouldn't be mistaken as a public park grade type rack if that makes sense. I personally have mine in the garage, but yes, you could theoretically use it outdoors. I would probably hit the screws and other pivot points with some silicone just to keep water from entering the frame since it comes in multiple pieces and must be assembled. Thinking it would rust out in a season or two if you didn't take this measure. We've had ours for 2 yrs and it's held up fine so far.
