China’s extensive industrial infrastructure and skilled labor force contribute significantly to the efficient production of 36-inch cast iron griddles. The manufacturing process begins with the selection of high-quality iron ores, which are melted down in furnaces. The molten iron is then poured into molds to create the griddle shape. To enhance durability and cooking performance, many factories use a meticulous seasoning process that involves applying a layer of vegetable oil and baking it at high temperatures. This not only prevents rusting but also creates a natural non-stick surface.
