Service doors are specialized entrances designed for access to areas that require maintenance or service, such as mechanical rooms, storage areas, or utility spaces. They are typically located in commercial and industrial buildings, allowing staff to perform necessary tasks without disrupting the main flow of operations. These doors are often constructed from durable materials like steel or fiberglass to withstand heavy use and provide security. They may include features such as locks, weather stripping, and insulation to enhance functionality and energy efficiency, ensuring that service areas remain accessible yet secure.
