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

Cheaper than the supply house.
Size: 42'' x 28''
I used black pipe similar to this to build some shelves in my man cave. I went looking to build a studio desk and found that Lowe's wanted $8 per floor flange (~$96 just for flanges and not including the pipe, tees, or the other fittings). Even supply house dot com wanted $4 per flange (~$48, but was still missing the other parts AND they didn't offer them because of supply chain issues). For about $65, this was a great buy. Yes everything is greasy. This will be the case regardless of where you buy it. I used some gloves, shop towels, and acetone and it cleaned up easily. For a top, I used a pre-made countertop from Lowe's (~$100) and a 1x4 piece of poplar I had sitting around.

Pipes don't assemble square, nice stand though.
Size: 42'' x 28''
These arent standard SCH40 pipe for starters. Significantly lighter. Easier to move around and sturdy enough to support a table, but this isnt pipe. As such, when I threaded it together, it wasn't square. I was able to flatten it mostly, but I had to use a clamp to bend the assembled piping to sguare so it would attach to the table runners. It's fine, but it surprised me. It looks nice, and it provides plenty of support for the table. All good. Several folks complained that the pipes are oily. They are supposed to be to prevent rust. I wiped them down with a few cleaner wipes, and they are fine. Be aware that this doesn't come with instructions or the wood screws you may need for your table top.

Sturdy & Tuff going on 6 months +
Size: 28'' x 14'', Size: 28'' x 14''
I mounted a thick heavy piece of butcher block to these legs and made a desk. Easy to assemble and install. Mark the holes, pre drill pilot holes and screw them in. I will say I knew they were going to be greasy out of the box. They grease them in the factory to prevent rusting so just wipe them off with an old rag and your good to go. They haven’t felt wobbly or anything like that and butcher block is pretty heavy. I have to say I love them and much cheaper than buying from the hardware store. I’m thinking about building a second one and I would definitely purchase again. Again very sturdy and easy to assemble. People mad about the grease need to realize it’s done as an anti rust measure and it wipes right off and zero rust thus far.
