Stainless or copper fire pit

I don't reccomend an open fire of any kind on a wooden patio regardless.

So what do you recommend for a stone or concrete patio?

I make no reccomendation. This person has not mentioned a masonry patio. Opinion: any commerical fire pit would do with a stone or concrete base. Why do you ask? Just to be a smartass? I prefer you address your comment to the OP rather than to me.

You don't get to make choices on a public forum; you join in as part of a conversation. You made a statement. It did not answer the original question. I was curious about it. That is the purpose of the newsgroup, to learn.

Now it may vary by region, but around here, a patio is usually a stone, concrete, or other masonry area on the ground. Wood is used to make a deck, generally a raised structure. When the OP mentioned "patio" I assumed he was talking about a masonry structure of some sort.

PATIO A patio (from the Spanish: patio meaning 'back garden' or 'backyard) is an outdoor space generally used for dining or recreation that often adjoins a residence and is typically paved. It may refer to a roofless inner courtyard of the sort found in Spanish-style dwellings or a paved area between a residence and the garden. Patios are typically made of concrete or stone slabs laid over a firm base. This base is often formed of a layer of compacted hardcore (stone chips), a layer of sharp sand, and a layer of cement mortar. The firmness and stability of the base is essential to the robustness of the top layer of slabs - an infirm base will typically result in cracked slabs. Patios that hold a lot of weight, such as driveways, require stronger foundations than those that are designed for light use.

...I have a patio made from concrete pavers. ...Lawrence ("professional asshole" per your user profile)... I'm aware of the corrosion/heat problems with thin gauge plain steel, and that a thin steel screen will literally burn up, I'm considering manufacturing making my own spark screen from heavy gauge stainless mesh... I think I know not to build a fire on a wood deck. ; )

I'm still concerned that the thin gauge stainless and copper bowls ($99 range) may still be junk (short life span). Anyone have some direct experience?

What you need is a butt weld end cap in one of the larger sizes. I guarantee you that these will last a while. They are not something that you can just pick up anywhere and they are expensive, but if you want a fire pit to last, they are the way to go.
