Metal outdoor furniture can typically withstand winter conditions, but proper care is essential to prevent damage from moisture, temperature fluctuations, and corrosive elements. Whether you should store it or leave it outside depends on several factors including your climate, furniture quality, and protective measures available.
For harsh winter climates with heavy snow, ice, and road salt, storing metal furniture is highly recommended. Moisture accelerates rust formation even on powder-coated or aluminum surfaces. If you lack indoor storage space, use waterproof covers specifically designed for outdoor furniture, ensuring they are breathable to prevent moisture trapping.
Before winter arrives, thoroughly clean your metal furniture with mild soap and water, removing all debris. Apply a protective wax or sealant designed for metal surfaces to create an additional barrier against moisture. For furniture with moving parts, apply lubricant to prevent freezing.
Elevate furniture pieces slightly to prevent water pooling, and avoid placing them directly on wet surfaces. If leaving outside, position furniture in sheltered areas away from direct exposure to elements. Regularly remove snow accumulation to prevent excessive weight stress and moisture penetration.
High-quality aluminum and powder-coated steel furniture generally withstands winter better than untreated iron or cheap metals. However, even quality furniture benefits from protection. For moderate climates with mild winters, leaving furniture outside with proper covers may be sufficient.
Ultimately, storing metal outdoor furniture in a dry, covered space like a garage or shed provides the best protection against winter damage and extends your furniture's lifespan significantly.
