ENTRY DOORS The Learning Center A steel door isn't as industrial as it sounds. Most steel doors have surfaces of heavy-gauge galvanized steel that has been embossed with a wood-grain pattern. Some types are given a wood-fiber coating that allows them to be stained. High-end doors may even have real- wood veneer laminated to their surfaces. Conventional steel doors are factory primed with a baked-on polyester finish; they generally require periodic repainting. Some are given a vinyl coating for greater weather resistance. All have an inner frame that may be made of wood or—for greater strength—steel. There is a huge range in quality and price when it comes to steel doors. The gauge of the steel will tell you how strong the door is: the higher the number, the thinner the steel. While 24-guage steel doors are common, they should be considered temporary as they can rust and fall apart. Look for at least a 22-gauge door, which offers thicker steel that won’t bend or flex and holds paint well. Gauge numbers lower than 22 are generally used for commercial or industrial applications. If security and durability are your top priorities, a steel door might be your best choice. A steel door is far stronger than either fiberglass or wood. In addition, it won't crack, warp or come apart.     5.
