Door Slabs

Every MASTERGRAIN™ door is engineered and built in North America by skilled technicians to ensure the highest quality. Unlike other manufacturers, the processes and technologies that MASTERGRAIN™ employs eliminate the need to compromise strength for lasting beauty. MASTERGRAIN™ doors don’t warp, rot or crack like wood doors and requires less maintenance. They don’t rust or dent like steel doors, and are engineered for the extreme temperatures of North America with excellent grain and stain matching across fiberglass components.
