Aluminum is a very strong yet lightweight alloy that is well suited for construction of large metal planters. Aluminum is naturally rust-resistant and can be powder coated in just about any color. Powder coating is a durable and environmentally friendly coating process that contains no volatile organic compounds.
Unlike some plastic planters that can crack in freezing weather, or bow in hot sunny conditions, aluminum retains its structural integrity. See some pictures below of a 20”x20”x20” aluminum planter enjoying the sunshine, and in the winter being frozen solid. Planting in durable metal planters eliminates the need to winterize the containers by moving them inside to shelter the planters from extreme weather.
