UL 752 Bullet Resistant Door Protection

Liberty Shielding offers ballistic metal doors for both handgun and rifle threat protection.

UL 752 Level 3 Bullet Resistant Doors

UL 752 Level 3 is designed to resist the standard's specified .44 Magnum handgun threat.

Level 3 ballistic doors are commonly specified for facilities where protection against handgun threats is required while maintaining the durability and appearance of a conventional commercial hollow metal door.

UL 752 Level 8 Bullet Resistant Doors

For higher-security applications, UL 752 Level 8 provides protection against the standard's specified 7.62mm x 51 (.308) rifle threat.

The higher ballistic rating requires substantially greater protection than Level 3 and results in a heavier door assembly.

The appropriate UL 752 level should be selected according to the ballistic threat requirements established for the project.

Complete Bullet Resistant Door & Frame System

A ballistic opening is more than just a reinforced door.

Liberty Shielding's bullet resistant door and frame assemblies combine the ballistic door with a compatible steel frame designed to maintain protection around the perimeter of the opening.

Bullet Resistant Metal Door Construction

Our ballistic steel doors feature:

  • Minimum 16-gauge steel faces
  • Specialized internal ballistic core
  • Internal steel stiffeners
  • Welded flush edges
  • Steel top and bottom caps
  • Flush door construction
  • Heavy-duty hinge preparation
  • Ready-to-paint primer finish
  • Custom hardware preparation available
  • Bullet resistant vision lite options available

The result is a heavy-duty security door designed to provide ballistic protection without sacrificing the functionality expected from a commercial metal door.

Bullet Resistant Steel Frame Construction

The door frame is an important component of the ballistic opening and is manufactured to complement the protection provided by the door.

Standard ballistic frame construction includes:

  • Minimum 16-gauge steel
  • Ballistic reinforcement
  • Armor plating on the threat side
  • Fully continuously welded construction
  • Welded frame anchors
  • Ready-to-paint primer finish

Frame Anchors

Frames include a minimum of:

  • Four welded anchors per jamb for frames up to 7'0" high
  • Five welded anchors per jamb for frames up to 8'0" high

Proper anchoring and installation are essential to the performance of the complete opening.

Custom Bullet Resistant Metal Doors

Every ballistic opening is different, so these doors and frames are custom fabricated to your selected dimensions and preparation requirements.

Available Door Sizes

  • Maximum Width: 48"
  • Maximum Height: 96"
  • Custom dimensions within the allowable size range
  • Custom door and frame preparations
  • Bullet resistant vision lite options
  • Hardware preparations available

The door and frame should be ordered according to the project's approved opening, hardware, handing, wall construction, and security requirements.

Heavy-Duty Ballistic Door Construction

Ballistic doors are considerably heavier than conventional commercial hollow metal doors because of the protective materials contained within the assembly.

A standard 3'0" x 7'0" bullet resistant door weighs approximately 275 lbs.

A larger 4'0" x 8'0" ballistic door can weigh approximately 385 lbs.

Hinge Requirements

A standard 3'0" x 7'0" door is equipped with at least:

  • Four 4-1/2" heavy-weight hinges

For doors wider than 36" or taller than 84", additional support is recommended, such as:

  • A continuous hinge rated for at least 500 lbs., or
  • Five heavy-weight hinges

The correct hinge configuration is important for supporting the weight and maintaining reliable long-term operation of the door.

Bullet Resistant Doors with Windows

Need visibility through the secured opening?

Bullet resistant door vision lites are available for compatible door configurations, allowing the door to maintain visibility while incorporating ballistic-resistant glazing.

The ballistic rating of the glass and vision frame should correspond with the protection requirements of the complete opening.

Standard architectural or safety glass should not be substituted where ballistic protection is required.

Fire-Rated Bullet Resistant Doors

Certain configurations are available with both ballistic resistance and a UL fire rating, providing two types of protection within the same opening.

Available fire ratings can extend up to 3 hours under UL 10C, depending on the specific door, frame, hardware, glazing, dimensions, and configuration.

Fire ratings are not available for every ballistic door configuration. Where a fire rating is required, the complete assembly must be configured to meet the applicable project and opening requirements.

Where Are Bullet Resistant Doors Used?

Bullet resistant steel doors and frames are used to protect entrances and interior openings where firearm threats are part of a facility's security design.

Common applications include:

  • Schools and educational facilities
  • Government buildings
  • Courthouses
  • Police and law enforcement facilities
  • Banks and credit unions
  • Financial institutions
  • Security offices
  • Pharmacies
  • Healthcare facilities
  • Cash-handling areas
  • Utility facilities
  • Critical infrastructure
  • Guard stations
  • Security checkpoints
  • Commercial buildings
  • Data and technology facilities
  • Safe rooms
  • High-security facilities

Because the finished product resembles a heavy-duty commercial metal door, ballistic protection can be incorporated into a building without making the protected opening visually conspicuous.

Bulletproof Doors vs. Bullet Resistant Doors

You may see these products described as bulletproof doors, bulletproof steel doors, or bulletproof security doors, but bullet resistant door is the more accurate terminology.

Ballistic doors are designed and tested to resist specific firearm and ammunition threats associated with their ballistic rating. They should not be assumed to stop every possible firearm or projectile.

The project's security requirements should therefore determine the appropriate UL 752 ballistic protection level.

Ballistic Doors vs. Standard Hollow Metal Doors

A conventional hollow metal door may look similar to a ballistic steel door from the outside, but the two products are designed for very different purposes.

Standard commercial hollow metal doors are not inherently bullet resistant.

A ballistic metal door incorporates specialized protective materials within the door construction to resist penetration from specified ballistic threats.

The frame and other components surrounding the door must also be appropriately designed when ballistic protection is required for the complete opening.

Complete Ballistic Opening Protection

Installing a bullet resistant door does not automatically make the entire wall or entrance bullet resistant.

A complete ballistic barrier may involve:

  • Bullet resistant door
  • Ballistic door frame
  • Bullet resistant vision glass
  • Ballistic vision frame
  • Appropriate hinges and hardware
  • Ballistic wall panels
  • Protected wall penetrations
  • Proper frame anchoring
  • Appropriate installation methods

The surrounding walls and adjacent building components should provide protection appropriate for the project's specified ballistic threat.

Typical Lead Time

Each bullet resistant metal door and frame is custom fabricated according to the selected dimensions and preparation requirements.

Typical manufacturing lead time: 5–6 weeks.

Actual production time may vary based on the door size, ballistic level, hardware preparation, glazing, fire-rating requirements, quantity, and other custom options.
