Leaving metal urban outdoor furniture outside throughout the year is a common concern, as exposure to rain, snow, and humidity can lead to rust. However, whether your furniture will rust depends heavily on the type of metal and its protective finish.
Stainless steel and aluminum are highly rust-resistant and are excellent choices for all-weather use. They form a protective oxide layer that prevents corrosion. Wrought iron, while sturdy, is prone to rust if its protective coating is scratched or damaged.
The most critical factor is the protective finish. Powder coating is a durable, baked-on finish that creates a robust barrier against moisture. Regular paint or a simple sealant offers less protection and will require more frequent maintenance.
To prevent rust, place furniture in a covered area when possible and use protective covers during harsh weather. Regularly clean with mild soap and water, and immediately touch up any scratches in the finish to seal the metal from moisture. With the right metal and proper care, your urban outdoor furniture can withstand the elements year-round.
