Hi-Flame Tray Ash Pan Clean-Up Expandable for up to 30" Basket Fireplace Grate, Sliver Color

do you offer a rectangular pan that's as wide is the back as it is in the front for see thru fireplaces?

what material and thickness is this made out of? my last ash pan slowly melted away.

Will this pan work without using grill?

Since this pan is made from galvanized steel (zinc coated), would this be an inhalation hazard using this in an enclosed space when heated?
