Which type of fire door is commonly used to protect firewall openings in industrial settings?

The overhead rolling steel fire door is commonly used in industrial settings to protect firewall openings due to its robust construction and space-saving design. These doors can be easily rolled up and stored above the opening, providing clear access when not in use. They are typically made of steel, which enhances their durability and offers a high level of fire resistance, essential in environments that may encounter larger fires or hazardous materials.

In industrial settings, where large openings are often required for machinery, vehicles, or equipment, overhead rolling steel fire doors effectively integrate fire protection while maintaining operational efficiency. This type of door can also be equipped with various safety features, such as automatic closing mechanisms, to ensure compliance with fire safety regulations and to protect the integrity of firewalls.
