Definately want to avoid heating up galvanized metal, especially around food. Very toxic. Never use hardware cloth as a grate to grill your meats either. And if you weld galvy make sure the area is well ventilated.
Tried a similar factory built stove that a friend had. Forget the name. "Gassifies" the combustibles which is supposed to be more efficiant. It worked O.K.
