Grade 4 & Bulletproof security Doors

Our Grade 4 / Bulletproof security doors are built for projects requiring elevated security in a seamless, modern form. Reinforced with additional internal steel layers and ballistic-grade materials, these doors are engineered to withstand high-impact force and targeted intrusion. With robust hardware and structural upgrades over Grade 3, they’re ideal for secure residences, embassies, and commercial entrances – delivering top-tier protection without limiting bespoke design.

Next-Level Protection. Unlimited Design Freedom.

For projects that demand an even higher level of security, our Grade 4 and bullet-resistant doors offer advanced protection without limiting creative freedom. Internally, these doors are reinforced with additional steel components and ballistic-rated materials, offering resistance to forced entry, targeted attacks, and – where required – certified bulletproof performance.
Security features include upgraded multi-point locking systems, reinforced core structures, anti-drill protection, and impact-resistant armour – all integrated within a concealed framework designed to accept any finish. Despite the increased strength, every door remains fully customisable in size, finish, detailing, and hardware. Whether blending into a luxury interior or making a bold architectural statement, the exterior is yours to define.

ADDITIONAL features

Door glazing & Biometric system

Security door glazing

Our security glazing is engineered to match the strength and standards of our doors. Whether integrated into the door itself or as side and top panels, it delivers both protection and visual appeal. We use triple-glazed, triple-laminated glass as standard, with a 44mm profile featuring P6B security glass for outstanding impact resistance. An optional bulletproof upgrade is available. For projects with varied security needs, standard glass can be used on the outer layer—without compromising style or performance.

Biometric / fingerprint Access

Security & Convenience at Your Fingertip: your finger is the key. No more lost keys or forgotten codes—your fingerprint unlocks the door anytime with the ekey dLine scanner.
Advanced Biometric Protection: only authorized users can enter—1,000 times more secure than a 4-digit PIN.
Smart Integration: grant access remotely, use voice commands, and get alerts when family arrives. Simple, secure, and connected.
