When security requirements are paramount and a standard residential entrance is insufficient, Premium High Security Doors represent the pinnacle of structural fortification. These systems are engineered to withstand sophisticated forced-entry attempts that would compromise traditional hardware.
Our premier RC4-rated best security doors represent the highest standard of structural fortification, featuring a comprehensive assembly of stainless steel for the frame, leaf, and threshold. These units are precision-engineered from top-tier RUUKKI galvanised stainless steel, ensuring maximum resistance against sustained mechanical attack.
The architectural integrity of the door is further enhanced by: Engineered EDM Wood: Utilizing advanced technology, this material provides a 50-year life expectancy, ensuring long-term durability and aesthetic refinement.High-Performance Hardware: The assembly is supported by heavy-duty PETTITI adjustable hinges, designed to maintain perfect alignment under the weight of reinforced materials. Advanced Glazing Options: For designs requiring vision panels or side-lights, we utilize P8B burglary-resistant glass. This triple-glazed, laminated security glass is certified to EN 356 standards and can be upgraded to ballistic-rated specifications upon request.
By combining rigorous metallurgical standards with sophisticated wood engineering, these systems provide an uncompromising barrier for high-risk environments.
Our distinguished range of high security doors delivers a sophisticated synthesis of robust perimeter fortification and refined architectural elegance.
120 MINUTES FIRE RESISTANT UPGRADE – This door can be upgraded to provide fire resistance for up to two hours.
RESISTANT TO POWERED TOOLS – Our Premium security doors are precision-engineered to withstand heavy-duty tools, including power saws, drills, and sledgehammers.
CROWBAR RESISTANT – The Premium security door is engineered to withstand heavy-duty forced entry implements, including 700mm steel crowbars. The door frame incorporates a unique steel box section designed to compress upon impact; in the event of a crowbar attack, this mechanism deforms to create a physical deadlock, effectively halting the intrusion.
FRAME INSTALLED WITH 24 BOLTS – A 115 mm stainless steel frame is integrated into the wall structure using a minimum of 20 fasteners, reinforced with specialised steel liners and secondary screws to prevent breach via the wall. This configuration ensures optimal frame alignment, supported by two floor-anchored screws and four concealed fixings for enhanced structural security.
PETTITI ADJUSTABLE HINGES – With PETTITI adjustable hinges, the height of the door leaf can be precisely configured to accommodate various floor coverings or mats. As a standard specification, all RC4 doors are equipped with four hinges per leaf to ensure superior structural integrity and smooth operation.
10-YEAR WARRANTY – Every door is supplied with a standard 10-year guarantee covering the steel construction; however, they are engineered to last for several decades to come.
LOW MAINTENANCE – Designed for durability, our doors are exceptionally easy to maintain; a simple wipe down with a damp cloth is all that is required to keep them looking their best.
Multi-point locking system – The system incorporates comprehensive security features, including a multipoint locking mechanism and a Grade 7 MOTTURA 8th series lock protected by a manganese anti-drill plate. The configuration employs vertical bolts and eight lateral bolts, providing an auxiliary lock compared to the RC3 PLUS. Ten fixed bolts secure the hinge side (extra 6 compared to our RC3 version), neutralising attempts to compromise the heavy-duty hinges. The escutcheon includes an anti-drill spinner, while an external magnetic lock blocks keyhole access against picking tools or decoders. Consequently, the RC4 is recommended for high-risk environments, combining impenetrable physical resistance with advanced technology to prevent silent or rapid forced entry.
UNFORGEABLE KEYS – We only use Yale type security cylinders which are impossible to duplicate, copy keys without secret code card or pick with manual lock picking tools. Additionally, an auxiliary lock with no external keyhole can be installed; when secured internally, this renders the door entirely impenetrable from the outside.
Stainless steel hinge caps – Furthermore, these units feature precision-engineered steel hinge covers, available in bronze or stainless steel finishes. Even on internal doors, these covers serve as an additional protective layer for the hinge mechanisms.
NOW ANY SHAPE – In contrast to standard security doors London, highest security doors manufacturing allows for integration with side and top panels. These units can be configured as double-leaf doors, incorporate top fanlights, or be engineered as passage doors.
FIRE RESISTANT – Premium security doors provide a 30-minute fire resistance rating as standard. This specification may be further enhanced to a 60-minute or 120-minute fire rating (*available upgrade).
THERMALLY INSULATED – Our doors offer outstanding thermal performance, achieving a U-value of 1.5 W/m²K.
SOUND INSULATED – Tested for 45 dB acoustic protection and are flawless to be the security front entryways for boisterous lanes
TESTED FOR DURABILITY – Our doors have been rigorously tested for durability, completing 200,000 opening and closing cycles while remaining fully operational and structurally sound.
PROTECTED FRAME SCREWS – The edge bolts are secured with reinforced steel sleeves to mitigate the risk of tampering or cutting, providing a secondary layer of protection should an attempt be made to compromise the mechanism from the masonry wall.
PATENTED CONSTRUCTION – With a 120mm steel frame and a door leaf thickness of 100mm, these security doors can comfortably withstand the impact of an SUV. The stainless steel frame incorporates eight reinforced edges, providing superior structural integrity compared to any other British-manufactured frame. This advanced profile also ensures it is more straightforward to infill with stone wool, silicone, expanding foam, and other hermetic materials.
ANY SHAPE, DESIGN and MEASUREMENTS – These highest security doors can be engineered to any shape, profile, colour, and dimensions.
CERTIFIED and TESTED FOR HIGHEST STANDARDS –Tested significantly beyond the requirements for RC4 classification in accordance with EN 1627.
Our highest security doors represent the finest protection money can buy to safeguard you and your family from an intruder’s attack.
CUT PROTECTIVE DOOR HINGE PINS – 8 units of 16 mm hinge bolts fixed to the door leaf edge allows this door to achieve the same security rating for inward and outward openings.
SUPERIOR SOUND INSULATION – Our doors are tested to serve as a definitive sound barrier against the outside world. Certified for over 44 dB of sound resistance, they are the ideal choice for anyone who values peace and quiet.
