It starts with steel.
A vault's door is usually its weakest point of entry and is vulnerable to prying, cutting, and drilling. We negate this weakness with a half inch of solid plate steel. This steel thickness increases with each protection rating.

To ensure maximum lock protection from all penetration based attacks, we completely encase the vaults inner lock with our highest rated penetration resistant ballistic armor plating. Capable of deflecting a direct hit from a 50 caliber bullet, this armor outperforms all known metals in penetration protection.

Our vault door and it's frame incorporate a highly overbuilt interlocking design where each anchor point acts as a redundant interlocked anchor for additional anchor points. The resulting assembly allows for flexibility during installation with unyielding rigidity once the door is locked in place.

The solid welded overlapping steel flanges on both sides of the door's frame firmly binds the door within it's opening while completely sealing out any perimeter vulnerability.

In addition, the solid steel reinforced door interlocks within the door frame, creating a flush surface of solid backed steel that prevents the insertion of any pry bar or hydraulic leverage mechanism.

A solid steel tongue runs the entire length of the inner door parallel to the hinge. It locks in securely behind the door frame when the door is fully shut interlocking the door and frame tightly together. Once closed and engaged, this jamb coupled with the flush frame design and hardened locking bolts creates a door capable of withstanding extreme forms of attack for extended periods of time. With the inner jamb in place, any effort spent cutting the doors exterior hinges wastes valuable time for the criminal while gaining them nothing.

This large hard plate rests between the door and the lock creating an additional barrier against penetration attacks. The plates is comprised of a thick, dense, and costly carbide material, the same ultra dense material that is embedded in the tips of high grade drill bits used to attempt entry into safes, chip carbide hardplate is a safe crackers worst nightmare as it will dull and/or shatter countless drill bits that attempt to penetrate its hardened jagged surface.

The locking bolts responsible for securing the door are fastened at two distinct locations along each bolt. Each paired set of solid steel anchors is spaced wide apart for additional support. The carriage anchors are held fast directly to the plate steel door by seamless welds.

This robust method of bolt carriage reinforcement is rarely seen in the safe industry. The majority of safe companies hold their bolts using a single thin carriage anchor, making the safe extremely vulnerable to pry bar and leverage based attacks.

A solid door requires solid bolt work, and our bolts deliver. Each case hardened locking bolt runs directly through the carriage anchors.

While the locking bolts on most safes terminate just inside the door, each Brown Safe bolt runs over half the length of the door passing directly through the wide set bolt carriage anchors. While in the locked position, each bolt is equipped with a passive anti-drive mechanism that blocks any attempts to mechanically force the bolt back through the use of wedges, taps, drills, and hammers.

Hardened relocking bolts positioned at key locations throughout the safe act as an end all failsafe against intrusion. If an attempt is made to penetrate the lock, all relocker bolts instantly engage permanently pinning the door and its main bolts solidly in place and making it a near impossibility to get the door open within any reasonable remaining time the criminal may have.

Once relocker bolts have activated, the vault door must be opened by a certified locksmith using blueprints supplied by Brown Safe specific to that door. Without these detailed prints and instructions, it takes numerous hours to gain access to the safe, ensuring the safety of the precious contents within.

To best accommodate the mass of our vault doors, all doors come standard with high load bearing ball and roller hinges. The result is an exceptionally fortified door with silky smooth operation.

The E rated (TL-15) vault doors weigh in with a massive steel thickness of 1½". This is triple the steel thickness over the base rating and accounts for the TL-15 protection rating.

This is the highest standard protection rating we offer for a vault door.

S rated vault doors combine a ½" of ballistic armor along with a ¼" of copper layered between a piece of ¼" ballistic armor, bringing the door's total thickness to 1". While only 1" thick, the extreme strength of the ballistic armor provides far more protection than standard steel three times thicker. The addition of a second layer provides a substantial increase in protection from penetration attacks, functioning as a hardplate for the entire door.

In addition to the superior strength of the ballistic armor layers, S rated safes gain significant resistance to torch and thermic lance attacks by the inclusion of a ¼" layer of solid copper. The highly conductive nature of copper rapidly dissipates the heat generated by torch based attacks, negating that means of entry.

Every vault door model we offer is upgradable to a composite cladded fire vault.

Our superior fire protection cladding process encases the entire door in two and a half inches of hardened amalgamate. The resulting fire safe offers substantial fire protection, keeping the interior contents below flash point for 90 minutes at sustained temperatures of 1700°F. Click here to learn more.

Because of the high density, weight, and composition of our fire encasing materials, vault doors with fire protection also benefit from an additional level of burglary protection.

Once the door has been built with the desired level of burglary protection, the door is made fire worthy by encasing the door exterior within 2.5" inches of poured composite material comprised of a high pressure concrete based mixture.

The vault will keep contents within below paper flash point (350° F, 177° C) for 1½ hours at temperatures up to 1700°F (927° C).

Brown Safe is one of the only vault door builders to enhance the density of our composite fire material to provide a high level of increased burglary protection. Our special recipe high-PSI amalgamate is capable of dissipating the concentrated heat from torches, seizing saw blades, and fracturing drill bits.
