Direct Answer: Kangye uses high-quality materials across their product lines: SUS430 stainless steel for durability and food safety, cast aluminum for premium BBQ chambers and lids (excellent heat retention), cast iron for cooking grids and plancha plates (superior searing), enamel-coated steel for easy-clean fireboxes, and BPA-free stainless steel trays for food dehydrators. All materials comply with LFGB and FDA food safety standards.
