HPL (High Pressure Laminate), also called Formica, has often been used as counter tops, flooring, and table tops; areas that need to be tough on the surface and provide impact resistance.

The reason HPL is so popularly used in commercial door applications is because it is tough to withstand heavy traffic areas, especially for school and public facility. It is difficult to damage, easy to clean, and there is a wide variety of designs available.
The substrate, or core, of HPL door panels are commonly made of MDF (Medium Density Fiberboard) or solid wood core. These materials are heavy and warp easily if it is large or very thin door panels. Heavy doors are dangerous for young children to operate. They also tend to be expensive to install due to the extra structure, hardware required, and high labor cost.
