Gas stove top burner covers?

I have a fairly small kitchen, and as such, I would like to make a burner cover for it.

What I was thinking was something could be folded. Not only to save space when I don't need it on the stove at all, but in hopes of being able to keep it on half the stove, fold it up, and have access to two burners.

However, I am unsure what to use to do this. I know that the heat from an active burner would burn most woods, and produce a fire hazard. But, I don't know what other materials would be workable enough to do such a thing.

I was thinking of just covering the bottom of some MDF to reduce heat transfer through the MDF, as right now, that is what I am using when I am not using the stove at all.

Are the burners electronically lite or does it use a pilot light? Not many stoves now days use a pilot light for the burners just the oven. If it's a pilot light then a cover isn't a good idea. There is always heat coming off the surface of the stove with pilot lights. May not be noticeable now but once you put a cover over it it could start a fire with any flammable cover. If the cover fully covers the burners the removal and replacement of the cover could cause a bit of a breeze or vacuum that could put the pilot light out. Causing a problem with gas leaking into the space.

With the intention to cover 2 burners while still using the other 2 you'll have to make the cover out of all metal. If it's on a stove with a pilot light be sure to vent the cover. Lets say the cover is one large square. You'll want a 1" or so lip around the sides to fully cover the burners and make contact with the stove surface right? Add the venting along those edges. A piano henge down the center will allow you to fold it over to use only 2 burners. You may need to have some angle brackets running the length of it for support.

With metal in mind careful what you pick up at the hardware store. Don't use anything galvanized. I'm sure the stove won't produce enough heat to make it a problem but better safe than sorry. The galvanized coating on the metal is zinc. When heated/vaporized the resulting gas is toxic. But you should be able to find aluminum with little problem. You could try tracking down a local roofer who specializes in high end tile and slate roofs or does metal roofing. They should have the equipment and be able to source stainless or copper and get it folded for you.

They have pilots lights (oh the joys of living in an old building!). And it does produce heat, which is actually what spawned this question. I know this sounds unsafe, but I ensured the heat being produced would not burn the wood . I did this over a four day weekend when I never left the house. Due to how my apartment is built, I can maintain consent eye contact on cover, with a fire extinguisher on hand and the gas shut off cleared. I did stick some dowels on it [the MDF board] to ensure that there was air flow.

As for the covers, I'm not too picky on design, just so long as I can ensure that heat will stay on the bottom, so the top doesn't become warm to the touch. As I found out the hard way, it will toast bread...

As for metal, I know not to use galvanized metal. I feel stupid for not thinking of this, but I actually learned that tid bit from my dad who works with seemless siding. So he'll have access to sheet metal and breaks to do just such a thing.

In terms of safety your only option is going metal here.
Wood or plastic is no a god idea IMHO.
If you give the measurements to a metal joint they will be able to bend the corners for you on the two hafs, you can do it with a vice and a nice piece of angle iron as well but usually not as clean as on a bending machine.
All that is left is adding some hinges and silicone pads on the corners.
For the finnish you get spray enamel paint with a higher temp rating.

I kinda figured, I just didn't know if there was a species of tree that wouldn't burn (which...typing that out just sounds stupid...). Either way, these three answers have pointed me to sheet metal.

Assuming it is safe to cover the stove I would ideally use a sheet of stainless steel, 1.5 to 2 mm thick with the edges folded over.

If that is too costly then aluminum although it will scratch much easier.
