Understanding Hollow Metal Doors
Before diving into the installation process, it's crucial to understand what hollow metal doors are and their advantages.
What are Hollow Metal Doors?
Hollow metal doors are constructed from galvanized steel or stainless steel and are designed to provide enhanced security and durability. They consist of an inner core and an outer shell, which can be filled with various materials for added insulation or soundproofing.
Advantages of Hollow Metal Doors
1. Durability: Hollow metal doors can withstand heavy traffic and are resistant to dents and scratches.
2. Security: Their robust construction provides a high level of security against forced entry.
3. Fire Resistance: Many hollow metal doors are rated for fire resistance, making them suitable for fire-rated openings.
4. Low Maintenance: These doors require minimal maintenance, making them a cost-effective option over time.
5. Versatility: Available in various sizes and finishes, they can be customized for different applications.

Preparing for Installation
Proper preparation is key to a smooth installation process. Here are the steps to take before you start installing the hollow metal door.
1. Measure the Door Opening
Ensure that the door opening is the correct size for your hollow metal door. Measure the width and height of the opening and compare it with the door dimensions.
2. Inspect the Door Frame
If you are installing the door in an existing frame, check for any damage or deterioration. The frame must be square, plumb, and level to support the door properly.
3. Gather the Necessary Permits
If you are installing the door in a commercial building, ensure that you have the necessary permits and approvals from local building codes.
Step-by-Step Installation Process
Now that you're prepared, let’s go through the step-by-step process of installing a hollow metal door.
Step 1: Install the Door Frame
1. Position the Frame: Place the door frame into the opening, ensuring it is level and square.
2. Secure the Frame: Use screws to secure the frame to the surrounding structure. Pre-drill holes to prevent the frame from splitting.
3. Check for Plumb: Use a level to ensure the frame is plumb. Adjust as necessary and secure it in place.
Step 2: Attach Hinges to the Door
1. Mark Hinge Locations: Typically, hinges are placed 7 inches from the top and 11 inches from the bottom of the door.
2. Chisel for Hinge Plates: Using a chisel, create recesses for the hinge plates on the edge of the door.
3. Attach Hinges: Secure the hinges to the door using screws. Make sure they are flush with the door surface.
Step 3: Hang the Door
1. Lift the Door: With assistance, lift the door into the frame and align the hinges with the hinge plates on the frame.
2. Secure Hinges: Attach the hinges to the frame, ensuring they are securely fastened.
Step 4: Install the Lockset and Handle
1. Mark the Handle Height: Standard handle height is usually around 36 inches from the floor. Mark this location.
2. Drill Holes: Drill holes for the lockset according to the manufacturer’s instructions.
3. Install Lockset: Follow the manufacturer’s instructions to install the lock and handle.
Step 5: Add Weather Stripping
1. Apply Weather Stripping: Install weather stripping along the frame to ensure a tight seal against air and moisture.
2. Check Alignment: Close the door to ensure the weather stripping compresses evenly without gaps.
Step 6: Caulk and Seal
1. Apply Caulk: Use a caulk gun to apply sealant around the frame where it meets the wall.
2. Smooth the Caulk: Use a wet finger or tool to smooth the caulk for a neat finish.
Final Checklist
Before completing the installation, check the following:
- Ensure the door opens and closes smoothly without binding.
- Confirm that the lock functions correctly and secures the door.
- Inspect the weather stripping and caulk for any gaps.
