Overhead doors, commonly known as garage doors, are large doors that open vertically and are typically used in residential and commercial buildings. They are designed to provide easy access to garages, warehouses, and storage facilities. Overhead doors can be made from various materials, including steel, aluminum, wood, and fiberglass, and they come in different styles, such as sectional, roll-up, and tilt-up. These doors operate using a system of tracks and rollers, allowing them to slide up and down smoothly. Many overhead doors are equipped with automatic openers, which can be controlled via remote or smartphone apps for added convenience. Proper maintenance, including regular inspections and lubrication, is essential to ensure their longevity and safe operation.
