For outdoor environments, Fiberglass (FRP) and Bronze are the premier choices. Fiberglass is lightweight, weather-resistant, and highly customizable in terms of color and texture, making it ideal for realistic life-size replicas. Bronze or Brass offers the highest durability and a premium antique aesthetic, though at a higher cost. If you are looking for a cost-effective option for gardens, Resin or Magnesium Oxide (MgO) is suitable but requires UV-resistant coatings to prevent fading and cracking over time.
