Heavy-Duty Deadbolts: Metal doors can accommodate reinforced deadbolts, which provide extra strength and security against prying or forced entry.

Electronic & Keyless Locks: Many metal doors are compatible with keycard access, PIN codes, and biometric locks, adding a layer of security and controlled access.

Panic Bars & Exit Devices: Common in commercial and emergency exit doors, panic bars allow quick egress while preventing unauthorized entry from the outside.

Continuous Hinges & Reinforced Strike Plates: To prevent tampering, metal doors often have continuous hinges and reinforced strike plates, making it harder for intruders to force the door open.

Magnetic Locks (Maglocks): Used in high-security environments, maglocks rely on an electromagnetic force to keep the door securely closed until released by an access system.

Because of their durable construction and ability to integrate advanced locking mechanisms, metal doors provide significantly better security than wooden or fiberglass alternatives.

Can metal doors be bulletproof?

Yes, metal doors can be bulletproof when designed with specialized materials and construction. These doors are commonly used in banks, government buildings, military facilities, and corporate offices where protection against gunfire is essential. They are built using hardened steel, ballistic-grade stainless steel, or composite materials that absorb and disperse the impact of bullets.

Bulletproof metal doors typically feature ballistic steel cores, multiple layers of Kevlar, ceramic, or fiberglass, and reinforced frames and hinges to maintain structural integrity under attack. They are tested and rated according to UL 752 (Underwriters Laboratories) or NIJ (National Institute of Justice) standards, with protection levels ranging from handgun resistance (Level 1-3) to military-grade, armor-piercing rounds (Level 7-8).

For added security, bulletproof doors can be equipped with ballistic-rated glass panels, heavy-duty locking systems, and fire or blast resistance. These enhancements make them an ideal choice for facilities requiring maximum protection against armed threats.
