A garage door is a large door that provides access to a garage, which is typically used for parking vehicles or storing items. These doors can be made from various materials, including wood, steel, and aluminum, and come in different styles, such as sectional, roll-up, and tilt-up. They are designed to open and close either manually or automatically, often using a remote control or wall switch. Garage doors are equipped with safety features to prevent accidents, such as sensors that detect obstacles in their path. Regular maintenance, including lubrication and inspection of springs and cables, is essential to ensure their proper functioning and longevity. Proper installation and operation are crucial for the safety and security of the garage space.
