HDF (High-Density Fiberboard) is an engineered wood product made by compressing wood fibers with resin under high pressure and temperature. It is denser, harder, and stronger than MDF (Medium-Density Fiberboard).

HDF has a smooth surface, making it ideal for lamination, flooring, wall panels, and furniture backing. It is cost-effective, easy to machine, and resistant to warping but not suitable for areas with high moisture unless specially treated.
