How to Repair Cast-Aluminum Lawn Furniture

Cast-aluminum lawn furniture is available in many different styles, colors and functional pieces. You can find manufacturers that offer not only chairs, tables and chaise lounges, but end tables, coffee tables, hutches, bars and other pieces to make your patio entertaining experiences both comfortable and complete. Cast-aluminum furniture is both lightweight and durable, making it a popular choice for homeowners. This furniture will not rust even when left outdoors throughout the year. Unlike plastic lawn furniture, which is difficult to repair, cast-aluminum outdoor furniture can be welded and repainted to give many more years of service.
