Selecting the material depends on the environment and load requirements. For retail displays, high-density MDF (Medium Density Fiberboard) is the standard due to its smooth finish and cost-effectiveness. For garage or industrial use, PVC or cellular plastic panels are preferred as they are waterproof, mold-resistant, and easy to clean. If you are looking for high-end interior design, WPC (Wood Plastic Composite) or solid wood slats with acoustic felt backing are ideal for sound absorption and aesthetic appeal.
