“Stainless Steel is a corrosive-resistant alloy of iron, chromium, and, in some cases, nickel and other metals.” It is commonly used in kitchen appliances, cookware, medical equipment, and surgical tools because it won’t rust, is easy to clean, and very durable in those environments. Stainless steel is a poor conductor of electricity so it’s used often in buildings, bridges, and airplanes but you won’t find many boats made of it. Stainless steel won’t rust in rain but it will rust around saltwater so we don’t recommend this material for coastal areas. Even though it’s as recyclable as aluminum, the price point is much higher. It’s a thicker metal, stronger, and can last up to 60 years or longer. It also won’t expand or contract in the summer and winter so you don’t have to worry about it cracking or warping.
