How thick is the firebox steel?
Portage & Main Outdoor Water Furnace fireboxes are made from 1/4″ W44 cold rolled mild steel-which has proven to be the longest lasting, most welder friendly and easily accessible steel for outdoor wood furnaces. Ask your local welder friend, if you are not sure of the advantages of mild steel over stainless steel.
