BBQ Ashpan Heat and Coatings question

[Andy from Workshopshed]

I've a beat up old BBQ I'm repairing, and the ash pan which will house the charcoal needs replacing. It's about 19inches by 12inches

I'm looking at simply folding the edges of a steel sheet to make a new one. Two options I'm looking at are:

Galvanized steel sheet (Ebay)
Scrap Steel from old boiler cover c1990s (white powder coat)

A check online suggests that a "high heat" on a charcoal BBQ is (450 to 650 degrees F) or 230 to 350 deg C.

At these kind of temperatures would the galvanisation or power coat give off fumes?

Any different recommendations for material/coating? I was thinking that stainless would be a waste of money but open to suggestions.

Wife suggested buying a new BBQ but I thought it would be more fun to fix.

DO NOT USE ANYTHING Galvanized or with a powered coating on big NO NO NO
A bit of 2-3mm sheet steel will do you(cheapest) and will last ages as long as your not having BBQ's 24/7,when the bbq season has finished give it a good clean wipe down with veg oil pack away out the eliments be all nice for next year

Stalwart, thanks for the clarification. 2mm might be a bit of a challenge to bend but I'll stick to mild steel with no coatings for this one.
Cheers,
Andy

If 2mm is too thick for you to bend, cut halfway thro' the bend line with a thin cutting disc,
It will then bend easily. you can then run a bead of weld along the bend line to give back the original thickness.

I recently used some Thermacure paint on a BBQ hood. I think its rated to 650 deg supposedly so might do the job youre after. Used a metallic finish one and got a pretty good result. Easy to use.

Agree with the other comment, you could leave it in bare steel but i guess that depends how often you are using it. Mine is everyday so rust doesnt get time to grow!
