Wrought iron urban outdoor furniture can develop rust over time when consistently exposed to rain and snow, though its durability makes it more resistant than other metals. The iron contains a small amount of carbon, making it stronger than pure iron, but without proper protection, moisture will eventually cause oxidation.
Several factors influence rust formation:
- Protective coatings: Powder-coated or galvanized finishes significantly slow rust development
- Maintenance frequency: Furniture receiving regular care resists weathering better
- Climate conditions: Coastal areas with salt air accelerate corrosion
- Quality of iron: Higher quality wrought iron contains fewer impurities that promote rust
Preventative measures include:
- Applying specialized metal sealants annually
- Using waterproof covers during harsh weather months
- Cleaning with mild soap and water regularly
- Addressing scratches immediately with touch-up paint
- Storing indoors during extreme winter conditions
While all iron can eventually rust, properly maintained wrought iron furniture typically lasts decades outdoors. Many urban designs incorporate modern protective technologies that dramatically extend its lifespan despite exposure to precipitation. The characteristic strength and classic appearance of wrought iron continue to make it a popular choice for outdoor furnishings, with many manufacturers offering extended warranties against rust through proper maintenance.
