I am going to build a fire pit, and ran into a few difficulties with alien things I have read online. When looking up various DIY projects or 'how to' videos on building a fire pit, a galvanized steel ring is set on the inside of the brick band. I accept read that heating up galvanized steel releases dangerous fumes, and also read that the zinc layer on the steel will be removed at under 400 degrees F. We know a bonfire will vary in temperature, but a few sources I take read say over 1500 degrees F. Steel melts at around 2500 degrees F, so I imagine the burn down ring would non end up melting. Does the thickness of the ring have an impact on how constructive it is containing the burn down? Is using this galvanized steel ring safe / smart / required at all? If so, I was planning on buying steel sheets and riveting them together to build the ring myself as it is cheaper. What are my alternatives?

  • Are you planning to build some other enclosure effectually the fire? You tin brand that out of a diversity of materials, or you can choose not to have one (after all, yous can build a burn down on just a flat surface). You certainly don't have to utilize a metal band. If yous're going to install a commercial enclosure, it may crave a band or it may be useful to ensure you've left the right space for it.

  • @ShimonRura, Going to surround the band with some sort of landscaping bricks. I think the idea behind it is "information technology is ameliorate for a ring to burn down that all the bricks" ?

Galvanized gives no do good. However.the tiny mount of zinc oxide produced would be no problem . I would suggest a local weld shop may take some stock to brand yous something. Material at least 1/eight" ( 3 mm) thick if y'all want it to last awhile. Stainless steel is pretty common, either the magnetic ( similar auto frazzle) or non-magnetic. Stainless would non need to exist every bit thick. Endeavor a local junk m.Bolts would be much more applied than trying to rivet. If you could detect information technology, brusk length cutting from big pipe like 24" diameter. Or , the sometime stand-by, 55 gal drum , cut off a human foot of drum.

  • I would use mild steel much easier to piece of work with than stainless. In the base I would utilise a fire clay or mortar mix like we put in the base of operations of sheet metal wood stoves. The 55 gallon idea gets a + for me as we have used them for burn drums on the farm for many years.

I answered your question. 1 Steel is a improve pick than galvanized for the reason you gave. 2 A weld is preferred to bolts. What is it you need assistance with cut steel or, using a drill scrap? Making a circle is easy. You also need fire rated paint if y'all don't want rust. I also gave other options, including purchase of one, that will not rust for a long time. Information technology besides has no gamble of fumes. Grass removal is also primal. I guess yous need to be more specific.

  • No paint volition hold upwards at the base of operations where the coals are if in direct contact with the steel. bolts will work only fine equally will rivets if made of steel aluminium rivets will melt close to the base.
