Make Grill for gas stove top

Hi All,
I would like to make a grill that will cover my gas stove top. Average size of a 4 burner stove but it has 5. It could even be a little larger. Can sheet steel work? Can it be sanded to an appropriate finish so as not to stick. 3/16" or 1/4" thick? I really like the Hiroshima Style Okonomiyaki, I saw on YouTube. Basically a japanese pancake with a massive amount of cabbage sprouts, noodle fried, bacon, topped with an egg with 3 oysters. Would also be handy for get togethers. Grill steel looks milled and grills are quite expensive. Any suggestions? Thanks, Fred

Fred, The sheet steel would be too thin I believe. Plate steel might work better. Longer to heat but even distribution. I would not bother with sanding either. Season it as one would with Cast Iron or use oil to keep from sticking. I think Lodge sells a cast iron grill sheet for pancakes, etc...

Thanks Greg,
But I need more room than a lodge grill or any other grill top that I've seen.
This is what I'd like to make and it takes a lot of space.

It's 12 minutes and only someone interested in food porn would sit threw it.
Pancake, cabbage, 2 types sprouts, bacon, noodles, eggs, oysters, sauces and sprinkles of ...

Thanks again for the reply.

Try going to a restaurant equipment supply. If they don't have one, perhaps they could get you a 'replacement' grill from a manufacturer.
Or better yet, if they have a trade-in that cannot be repaired, they may be happy to "part-it-out".

Hi John, I think you're right. I was just hoping for a cheap solution.
Thanks,
Fred
