The product description states that each leg has a maximum weight capacity of 220 lbs, and the set of 4 legs can support up to 880 lbs in total. This suggests that the hairpin legs are suitable for supporting heavy furniture like desks.

The product description states the mounting plates are 0.16 inches thick and made of carbon steel, which helps prevent bending.

The product description doesn't mention anything about suitability for outdoor use. However, it does mention that the hairpin legs are made of carbon steel with a powder coating finish.

Yes, the hairpin table legs come with rubber floor protectors to prevent scratches and dents on floors. The product description states, "Comes with 4 hairpin leg feet protectors to keep your floors away from damage and allows you to silently move the table."

I would do a little searching I know what you're talking about they come with the legs when you buy them I'm sure if you reach out to one of the sellers maybe they could help you out with that?

I doubt it. I received a set without the non-slip rubber feet and the manufacturer was unable to provide me with a replacement set. They suggested I return the set and order a new set. I chose not to do so.
