When choosing a metal garden bench, the finish isn't just about color—it's about long-term performance. The core difference lies in the application process and final result. Powder coating involves electrostatically applying a dry powder to the metal, which is then cured under heat to form a hard, seamless skin. Painting typically involves spraying or brushing liquid paint onto a primed surface, which air-dries into a film.
Powder coating is renowned for superior durability. The thermal bonding creates a thicker, more uniform layer that resists chipping, scratching, and fading far better than most paints. It's exceptionally resistant to rust and corrosion, making it ideal for benches exposed to harsh weather. The finish is also more flexible, allowing it to withstand minor impacts without cracking.
Painted finishes, while often more affordable upfront, generally require more maintenance. Traditional paint can chip or peel over time, especially if the metal wasn't properly pre-treated. Touch-ups are often needed to prevent rust spots from forming. However, painting allows for easier custom color matching and can be simpler for DIY repairs.
For longevity and minimal upkeep, powder coating is the clear winner for permanent outdoor fixtures. It withstands UV rays, moisture, and temperature swings with grace. Painted benches can be a good budget-friendly choice for covered or seasonal use, where they face less direct weathering. Your decision ultimately hinges on your climate, budget, and willingness to perform periodic maintenance to preserve the bench's appearance and structural integrity.
