Buyers should prioritize materials based on the target market's price point and durability needs. Solid wood (Oak, Pine, Walnut) offers premium appeal and longevity, while MDF (Medium-Density Fiberboard) with wood grain veneers provides a cost-effective alternative for mass-market retail. For modern aesthetics, Aluminum frames are preferred for their lightweight and rust-resistant properties. Ensure that PS (Polystyrene) frames are used for budget-friendly, shatterproof options, particularly for high-volume promotional items.
