Engineered Steel Security Entrance Doors for Global Projects
Novor Front Door Technology Co., Ltd. custom manufactures industrial-grade steel security doors designed for multi-family residential developments, commercial offices, government facilities, and luxury villas.
Built using high-gauge cold-rolled or galvanized steel plates, anti-pry lock channels, and 13 to 17-point vault locking mechanisms, our security doors provide certified protection against forced entry, burglary, and harsh climate conditions.
Each unit is engineered with high-density rock wool or sound-insulating polyurethane core, delivering enhanced acoustic isolation (up to 42 dB) and UL 10C certified fire resistance options up to 90 minutes.

Designed for Security, Fire Safety & Durability
Every steel security door manufactured by Novor Front Door Technology Co., Ltd. undergoes multi-stage structural inspections before export.
Multi-Point Locking System
Reinforced steel locking bolts engage across the top, side, and bottom frame channels to prevent prying, leverage attacks, and forced entry.
Heavy-Duty Anti-Pry Frame
Seamlessly welded steel frames with integrated anti-pry lips conceal hinge pins and locking tongues from exterior tampering.
Thermal & Sound Insulation
Injected with fire-retardant rock wool and perimeter weather-stripping to reduce energy loss and block noise in busy commercial environments.
Corrosion-Resistant Coating
Phosphate anti-rust treatment followed by electro-galvanized coating ensures 15+ years of exterior performance against salt spray and moisture.
Precision OEM Hardware Fitting
Factory pre-drilled for European profile lock cylinders, American standard mortise locks, heavy-duty door closers, and magnetic door sensors.
Export-Grade Packaging
Wrapped with protective PVC film, edge foam protectors, and sealed in heavy-duty wooden crates designed for long sea-freight transport.
Frequently Asked Questions About Steel Security Doors
What steel thickness is recommended for commercial security doors?
For standard residential apartments, a 0.8mm leaf with a 1.5mm frame is typical. For commercial, hotel, or high-security applications, we recommend 1.0mm to 1.2mm steel leaves combined with a 2.0mm galvanized steel frame for maximum structural rigidity.
Are your steel security doors certified for fire resistance?
Yes. Novor Front Door Technology Co., Ltd. manufactures fire-rated steel doors certified to UL 10C and CE EN standards. We provide ratings for 45-minute, 60-minute, and 90-minute requirements depending on project blueprints.
Can you manufacture steel security doors to custom project dimensions?
Yes. We offer complete OEM and ODM customization. Our engineering team creates 2D shop drawings and 3D CAD models based on your architectural rough openings and wall construction specifications.
What is your production lead time for bulk B2B orders?
Our standard production lead time is 15 to 30 days after shop drawing and sample sign-off. For multi-phase building developments, container shipments can be scheduled in staggered batches.
