Majestic Steel entry doors are an intricate part of home design. All of our Majestic Steel doors are galvanized to resist rust and corrosion, are comprised of 24-Gauge, high quality steel with 22-Gauge steel stiles and rails for additional strength and security. These steel doors come with a one-piece, high density polystyrene core delivering excellent insulation allowing it to meet or exceed current energy code standards. Each door comes with a 10 year warranty on the door component, a Limited Lifetime Warranty on the prehung unit as well as a 10 year glass lite warranty. Failure to finish all six sides of the door component will void all warranties.
