Grade 3 security Door
We merge high-level security with bespoke craftsmanship. Our Grade 3 security doors are UK-made, offering unmatched protection and timeless design
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.
Door structure
1. Medite Tricoya Extreme (MTX) Board
High-performance engineered wood panel offering exceptional durability, moisture resistance, and design flexibility. Its advanced composition allows for intricate detailing, custom finishes, and unlimited bespoke designs.
2. Door Leaf with Welded Galvanised Steel Frame & Rockwool Insulation
The door leaf is built from precision-bent, welded galvanised steel profiles, ensuring maximum strength and rigidity at its core. A multi-point, four-directional locking system provides superior security, while high-density Rockwool insulation enhances thermal and acoustic performance.
3. Door Shield 1.5mm Mild Steel
The Cold Reduced Oiled Steel forms the structural backbone of the door, delivering reinforced protection against physical attacks. Its strong yet lightweight composition ensures durability while maintaining smooth functionality.
4. Internal Umidax / Medite Tricoya Board
An internal board layer crafted from Umidax or Medite Tricoya, enhancing the door’s strength, moisture resistance, and fire protection.
5. Door Frame 2mm Galvanized Steel
The reinforced single “L” frame, made from 2mm galvanised steel, ensures exceptional strength, security, and longevity. Integrated Rockwool insulation enhances thermal and acoustic performance.

Door glazing & Biometric system
Security door glazing
Our security doors feature high-performance security glazing, seamlessly integrating within the door, or as side and top panels to accommodate any design specification. Engineered for both protection and aesthetics, our glazing options ensure that security is never a weak point, offering strength without compromising on style.
To ensure our glazing meets the same high-security standards as our doors, we use triple-glazed, triple-laminated glass as standard. With a 44mm profile, the outer layer features P6B security glass, providing superior impact resistance and intrusion protection. Optional upgrade to bulletproof glass. For projects with varying security requirements, the outer layer can be adjusted to standard glass without compromising the door’s aesthetic or overall design. This ensures seamless integration of security and style, meeting both functional and architectural needs.
