URBAN OUTDOOR FURNITURE

If you are allergic to certain metals, such as nickel, chromium, or cobalt, the powder coating on urban outdoor furniture is typically made from a mixture of finely ground pigment particles and resin, such as polyester, epoxy, or polyurethane. These materials are melted and applied electrostatically to the metal surface, then cured under heat to form a protective layer. Importantly, the powder coating itself is not metallic—it is a plastic-based polymer that does not contain the metals that commonly trigger allergies. However, the underlying metal frame (often steel or aluminum) may still contain trace amounts of allergenic metals. To minimize risk, look for furniture that explicitly states it uses "hypoallergenic" or "non-metallic" powder coating, or ask the manufacturer for a Material Safety Data Sheet (MSDS) to confirm the coating’s composition. Many outdoor furniture brands now use pure polyester or polyurethane powders that are free from heavy metals, making them safer for sensitive individuals. Additionally, ensure the coating is fully cured and intact—any scratches or chips could expose the underlying metal. If you are highly sensitive, consider furniture with a fully encapsulated powder coating over aluminum, as aluminum is generally less reactive than steel. Ultimately, powder coating is a durable, non-allergenic surface finish for most people, but verifying the specific materials used by the manufacturer is key to avoiding allergic reactions.
