Yes, you can put metal outside, but the suitability depends heavily on the type of metal and its properties.
While many metals can be used outdoors, their performance and longevity vary significantly when exposed to the elements like rain, humidity, and temperature changes. Some metals are highly susceptible to rust and corrosion, which can weaken them and reduce their lifespan quickly.
As noted in the reference, "some metals are better suited for outdoor use than others." To ensure high-quality, long-lasting service for items placed outdoors, choosing a metal known for its durability and resistance to environmental factors is crucial.
One excellent option you can consistently rely on for outdoor applications is aluminum. The reference highlights that aluminum is a material you can "consistently count on for high-quality, long-lasting service" when used outside. Aluminum naturally forms a protective oxide layer when exposed to air, which prevents further corrosion, making it ideal for outdoor furniture, structures, and components.
Choosing the Right Metal for Outdoor Use
Selecting a metal for outdoor exposure requires considering its natural resistance to environmental degradation.
- Corrosion Resistance: This is the most important factor. Metals that rust or corrode easily (like untreated steel) will deteriorate quickly outdoors.
- Strength and Durability: The metal should be able to withstand wind, impacts, and temperature fluctuations.
- Maintenance: Some metals require regular sealing or coating to maintain their appearance and prevent corrosion.
Metals commonly used successfully outdoors include:
- Aluminum: Lightweight, naturally corrosion-resistant due to passivation.
- Stainless Steel: Highly resistant to rust and corrosion, comes in various grades suitable for different environments (some grades are better for marine/coastal areas).
- Copper and Bronze: Develop a patina over time, which can protect the underlying metal. Used for roofing, pipes, and decorative elements.
- Galvanized Steel: Steel coated with zinc to prevent rust. Common for fences, pipes, and structural components, but the coating can wear off over time.
On the other hand, untreated plain steel or iron will rust quickly when left outdoors without protective coatings.
Ultimately, putting metal outside is feasible, but selecting a metal specifically engineered or treated for outdoor exposure, such as aluminum or stainless steel, is essential for durability and longevity.
