Selecting the appropriate material is critical for balancing cost and perceived value. Solid Wood (Oak, Pine, Walnut) is preferred for high-end galleries and premium home decor due to its durability and natural grain. MDF (Medium Density Fiberboard) with veneer is the most cost-effective solution for mass-market retail, offering a uniform look at a lower price point. For modern or minimalist styles, Aluminum Alloy frames provide a sleek, lightweight, and corrosion-resistant option, while PS (Polystyrene) is the go-to for ultra-low-cost, high-volume promotional items as it mimics wood but is significantly lighter.
