Residential vs. Commercial
Metal swing sets are available for both residential and commercial applications. Commercial swing sets are generally much larger than residential swing sets and require more outdoor space. They also tend to be constructed better, as they have to meet certain American Society for Testing and Materials (ASTM) safety standards for commercial use, according to Component Play Grounds.com.
Finishes
Metal swing sets may be constructed of galvanized metal or painted metal. Galvanized metal swing sets do not rust and are generally more durable than steel. Standard, steel swing sets often feature a powder-coated finish, which provides protection against the oxidation of the metal.
Age Recommendations
It is important to choose your metal swing set based upon the age of your children. Metal swing sets vary greatly according to size and design, so it is important to follow the manufacturer's age recommendations in order to prevent injury and to ensure maximum enjoyment.
