When sourcing ornate frames, the material dictates both the aesthetic and the price point. Solid wood (such as pine, oak, or paulownia) is the premium choice for durability and authentic grain. For complex baroque or rococo patterns, high-density polyurethane (PU) or resin is often used because it allows for intricate detailing that is lighter and more cost-effective than hand-carved wood. For budget-friendly bulk orders, PS (Polystyrene) is a common lightweight alternative, though it lacks the structural weight of premium materials.
