All of our Stainless Steel furniture is 304 grade, this is one of the strongest metal for exterior applications. Please note slight surface corrosion can occur due to salt and chlorine but can be removed with cleaning.
Grade A Teak is the most durable wood for exterior use. We recommend letting your teak grey naturally for that timeless classic look. Natural teak can absorb moisture and may develop cracks as it expands and contracts with hot and cold temperatures. UV will patina your teak to a silver/grey within months to a year depending on it's UV exposure creating that rustic teak look loved by many.
