What are commercial office bookcases actually built from?

Most commercial bookcases use a particleboard or MDF core covered in thermally fused laminate (TFL), which delivers durability, moisture resistance, and consistent finish quality. Steel units handle industrial and high-capacity environments, while solid wood or veneer bookcases are reserved for executive offices.
