Wire mesh fire proof for bbq

Stainless steel weldmesh.

This is harder to find and more expensive than galvanised mesh but galvanized mesh may give off toxic fumes when exposed to high heat.

I've most commonly seen stainless mesh in the form of insect mesh, but that's expensive and probably much too fine for your use.

Maybe make your own cage using stainless wire.

I was looking for expanded metal/woven wire mesh (stainless or galvanised) and found this thread. Can't seem to find any suppliers dealing in small diy quantities. Any help please? Looking for something for the bottom of my bbq, also a few different aperture sizes for soil/compost. Handy sizes of say 500x800 or so.

its more like a crematorium or this

One handy source of "mesh" is the local tip (sorry recycling center) and grab the trays out of any ovens they have. Any big electrical store may also have old cookers for recycling.

For stainless steel with a few holes in it an old washing machine drum is another option.
