Looks like real industrial steel
Pipes, excellent quality. Ordered another one for my sons room. I installed this initially where I didn’t want to put on closet doors  partly because of the expense and then because they always come off the tracks and break.

This rack makes the closet area look really modern and stylish.
It’s a look a lot of people are going for, so I think they’re an excellent buy for the price, cheaper than a standard closet rack in much better quality
