Will teflon-coated sheet metal flake when bent?

I’m considering having a metal shop bend some sheet metal to make trays for rising and baking french bread similar to this:

donald has kindly suggested that I start with a piece of teflon-coated metal like an edgeless baking sheet. I would have to ask the metalworker to take care not to scratch the surface, I imagine, and perhaps use a water-based glue or tape to temporarily affix a protective coating or cover like cardboard to it.

My question for you is, will a teflon coating flake off when the metal is bent? (I.e., does the coating have to be applied AFTER the metal is shaped?) Or does my plan sound reasonable?

I’m not sure about the flaking off,but what i can see is that if you do it with a piece of Teflon-coated metal like an edgeless baking sheet,even if you are successful in bending it,you’ll still have to make the 1000’s of tiny holes that are necessary to replicate the true purpose of those special trays.drilling a coated sheet will damage the integrity of the coating.

actually,i wonder why you want/need teflon coated ones…
we use uncoated metal ones,their non-stick properties come from the fact that it’s important never to wash them after use…a bit like IrishStu and Sandman

Yeah, I thought about drilling them, but wasn’t sure how useful the holes are in baking. After all, the steel is a good heat conductor.

I know I could just oil them and add cornmeal.

Maybe I’ll use stainless then, and drill it first?

And we get put away wet.

How do they make the bends in frying pans ?

I imagine they’re stamped or spun, since they’re round.

Dragonbones: Silpat Bread Forms. Flexible and durable, reasonably inexpensive and non-stick.

Oh, like this? http://www.jbprince.com/index.asp?PageAction=VIEWPROD&ProdID=1305 Interesting…

I might have to cut it down to size for my small electric oven. You wouldn’t happen to have any broken ones that I could trim down to a shorter 2-loaf size, would you? :smiley:

Did I mention how durable they are?

:laughing: Shot in the dark… But are they cuttable? I’ve been surfing online and most look to be too big for my oven.

I have an axe…

I don’t see why not. They are made of silicone and look like they could be cut fairly easily. By durable I mean that you can use them thousands of times, whereas teflon bread pans need to be resurfaced regularly.

you can cut them yes
