HBLYJS Industrial Pipe Shelving System
This shelving system gave my room a cool industrial look. The metal brackets feel heavy-duty and very stable. Installation took a little time but wasn’t difficult. I like that I can choose my own wood planks for customization. It holds a good amount of weight without sagging. The black iron finish looks great against the wall. This was a solid DIY upgrade for my space.

Easy storage, good holding power
This industrial pipe shelving system is a very nice way to add DIY storage to any room. The parts come well protected and are easy to assemble. They come with all the hardware one needs to install, though I used my own wall anchors because I like the ones I use and I know they work very well. I also decided in the end not to use the support legs because they would have had the shelves too low when mounted from the ceiling. Instead, I took those off and flipped the frames over so nothing would get in there, and I'll probably get nipples and caps from the hardware store to finish off the bottoms.
The frames are finished in black, and resemble old galvanized gas pipes. As previously mentioned, assembly is easy enough and they accommodate whatever width of shelf you want to put up, within a reasonable limit. I used 36" shelves because that's the space I had to work with. The fact that each flange has three screws, assuming this is installed correctly, it should be rock-solid. I know mine is. I installed this in our laundry room / craft room in order to get more storage space, because it is so very busy in there.
Given one could purchase the parts needed to build one of these for less, it's still a good value for the money because then after you buy those parts you have to clean and paint them, as well as prepare the boards. All I had to do was assemble these, and then prepare the boards, which made my life easier and the time saved was well worth the little extra. They also look fantastic with natural-colored oiled pine. I recommend these racks for their aesthetic, ascetic appearance, and their ability to hold a good amount of weight and storage, and not to mention if they're installed like mine, they will hold rolled leather hides like nobody's business.
