Kinda flimsy…
Thought the assembly was metal, it’s some kind of PVC.

Quality pipes for a good price
Size: 42inch Tall (NOT included wood planks), Color: Black
This item is just as described. It is the pipe fitting portion of a 3 shelf unit. You must buy your shelving separately once the rails have been installed. Purchasing the pieces this way was much more cost-effective than separately buying each part from the hardware store, and all the pieces were clean and ready to be mounted unlike the pieces from the hardware store. It was moderately difficult to hang, since you are trying to keep everything very level. I imagine the distance between each rail will be a factor in how easy this is to level. The difficulty may have also stemmed from the fact that we were mounting it in a small toilet room and had little room to maneuver during the installation process. Still, it is a good product and we are considering purchasing a second one for another location in our home.

Not real Black Iron, but works just as well
Size: 42inch Tall (NOT included wood planks), Color: Black
First, these parts that I got were not real Black Iron pipes like you would pick up at a hardware store, they are like furniture grade tubes for an IKEA shelving system. The thread would fit 3/4 pipe from like HD, but they are not the same, I know this because I just bought some of the pipe and parts for a small shelf right before ordering this. I should have known from the price, the real stuff is kind of pricey, but nicer. The elbows and T-connectors as well as the flanges seem more like galvanized steel painted black. HOWEVER, the end product is pretty nice and very versatile as to where you would want to put it. It is still pretty sturdy, and if screwed into a stud, I believe it would hold a lot of weight. The entire shelving system is painted black, so unlike Black Iron, it will not stain your hands black when handling it. Putting this together took about 30 min, the longest part was adjusting angles and lengths to get it flat and squared, but was not hard at all. This kit does NOT come with shelf boards, so length of that is up to you. It also came with mounting screws, but they are thin and I would suggest as your getting boards for shelves, also pick up some beefier screws, U used #12 - 1 1/4" wood screws with the sleeves for drywall and a little longer for securing it into a stud. All in all, this black pipe shelf looks nice, is nice and will work out great, just know, it is not the real Black Iron pipes and parts you would get from a hardware store, but the threads would fit if you wanted to add to this. I only knocked down one star because of this, and if I am going to buy more of these, I would prefer the real stuff and not go with this one.
