Stainless steel is resistant to corrosion and can withstand exposure to the elements without deteriorating. It is also easy to clean and maintain, making it a great choice for outdoor kitchens. Other materials that can be used for outdoor kitchen cabinets include teak, marine-grade polymer, and powder-coated metal. However, stainless steel is often the preferred choice due to its durability and resistance to corrosion.
