Fire-rated access doors are specialized doors designed to withstand high temperatures and prevent the spread of fire and smoke between different areas of a building. They are typically made from materials like steel and are tested to meet specific fire-resistance ratings, which indicate how long they can hold up against fire. These doors are commonly used in commercial and industrial settings, such as hospitals, schools, and warehouses, where safety is a priority. Installing fire-rated access doors helps ensure compliance with building codes and enhances overall fire safety by providing secure access to critical areas like mechanical rooms and utility spaces.
