Service stairs are stairs that serve areas only used for service rooms or service spaces, such as mechanical rooms, storage rooms, or utility rooms. Service stairs are usually located away from the main circulation areas and are not intended for public use. Service stairs are often designed to be more functional and durable than aesthetic, and they may have different requirements for fire safety, lighting, ventilation, and accessibility than other types of stairs. Service stairs can be made from various materials, such as concrete, metal, or wood, and they can have different shapes and sizes, depending on the space and the load they need to support.
