Grade 3 security Doors

Our Grade 3 security doors go beyond standard front doors, offering reinforced protection against modern intrusion tactics. Built with high-strength materials, tamper-proof hinges, and advanced multi-point locking systems, they are designed to withstand forced entry while maintaining effortless functionality. Beyond security, we provide endless design possibilities – from classic to contemporary, every door is fully customizable to match your vision. Whether replicating heritage details or creating a modern statement piece, our bespoke craftsmanship ensures that security never compromises style.

Bespoke Outside. Uncompromising Inside.

No matter the design chosen – traditional or contemporary – the internal structure of every door remains consistent: engineered for strength, precision, and long-term performance.
This cross-section reveals the hidden layers that deliver genuine protection. Inside, a welded steel core forms the backbone, paired with custom adjustable Pettiti hinges for smooth alignment and durability. Locking systems from Iseo or Mottura are shielded by a drill-resistant manganese plate and secured with solid cylinder defenders for added resistance.
Every frame is powder-coated steel, finished in any RAL colour, and built to endure without compromising the overall aesthetic.
While the look is yours to define, the strength beneath is always built to the same high standard.

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.
