Construction & Available Sizes

These solid core doors feature a thick internal frame reinforced with a chipboard core, offering superior strength compared to hollow core or medium-duty doors. The surface—made of MDF, Masonite, or Hardboard—is hot-pressed onto the frame. This process creates a smooth, seamless finish that enhances the door’s aesthetic appeal. Additionally, precision CNC-cut horizontal grooves add a sleek, modern look.
