Hollow metal fire doors are a popular option for commercial buildings due to their durability and fire resistance. However, proper installation is critical to ensure optimal performance in the event of a fire. In this guide, we’ll walk you through the steps to installing a hollow metal fire door.


Step 1: Measure the Opening

Before you order or purchase a hollow metal fire door, you need to measure the door opening to ensure that the door will fit properly. Measure the width, height, and depth of the opening and make a note of any irregularities or obstacles.


Step 2: Prepare the Door and Frame

Once you have your measurements, you can begin preparing the door and frame. Remove any existing hardware from the door frame and prepare it for the new door. Check the frame for any damage or warping, and repair or replace it as needed.


Step 3: Install the Hinges

With the door and frame ready, it’s time to install the hinges. Start by placing the door in the frame and aligning the hinges. Secure the hinges to the door with screws, then attach the other end of the hinges to the frame.


Step 4: Install the Lock set

Next, install the lock set according to the manufacturer’s instructions. Make sure the lockset is compatible with the door and frame and that it has been rated for use in a fire door.


Step 5: Install the Door Closer

Once the lock set is installed, mount the door closer to the frame. The closer should be mounted at the top of the door and attached to the jamb bracket. Adjust the arm and closing speed according to the manufacturer’s instructions.


Step 6: Test the Door

After installing the door closer, test the door to ensure that it closes properly and latches securely. The door should close smoothly and without any resistance. Make any necessary adjustments to the hinges and closer until the door operates smoothly.


Step 7: Inspect and Maintain the Door

Regular inspection and maintenance of your hollow metal fire door is crucial to ensure its continued fire resistance. Inspect the door periodically for damage or wear, and repair or replace any damaged components. Make sure the hinges are properly lubricated and maintain all seals and gaskets as recommended by the manufacturer.
