Selecting the appropriate material is critical for balancing aesthetics and durability. For high-end galleries or luxury decor, prioritize solid hardwoods like oak, walnut, or cherry, which offer superior longevity. For cost-sensitive promotional projects or high-volume retail, MDF (Medium Density Fiberboard) or PS (Polystyrene) frames are more economically feasible. If the frames are intended for moist environments like bathrooms or coastal hotels, aluminum or high-quality plastic frames are recommended to prevent warping and corrosion.
