Is the firewood stove made of iron or steel?

There are several kinds of firewood stoves in rural areas, the most commonly used ones are iron stoves and brick stoves. They have their own advantages and disadvantages. The iron stove is easy to move and does not take up much space, but its disadvantage is that it is not durable and easy to break down if it is not used often. The brick stove is fixed in one place, but it is relatively stable and will not break down for decades. It is also convenient to put seasoning next to it.
