What materials are U-shaped desks typically made from?

Commercial U-shaped desks are most commonly constructed with a particleboard or MDF substrate, high-pressure laminate surface, and steel leg frames. Executive-grade U-desks may use veneer surfaces. Steel frames are preferable to wood frames for large U configurations. FindOfficeFurniture.com carries commercial-grade U-desk materials — call 888-719-4960 for specifications.
