Engineering Features

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.

B2B Buyer FAQ

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.
