Fire-Rated Steel Security Door — Armored Entrance Door for Apartment & Commercial Buildings
Double-skin cold-rolled steel with internal reinforcement ribs, mineral wool fire core and multi-point locking, supplied as a complete steel door set against the certificate required by the project.
Buyer answer: what to confirm before ordering
For a project quotation, send the door schedule and the approval requirement together. This lets the factory review the complete door set instead of pricing an unsuitable leaf-only configuration.
- Opening size, wall thickness, handing and frame installation condition.
- Required fire-resistance or security standard, destination market and approving authority.
- Lock, closer, hinge, finish and threshold requirements, plus the project quantity.
- Target delivery date, destination port and export packing requirements.
Armored steel entrance door set for controlled project specification.
This Visfurn steel security door is developed for apartment entry, stairwell, office and commercial openings where the door leaf, frame, lock, hinge and seal must be treated as one coordinated assembly. The powder-coated or transfer-printed steel surface gives a clean architectural appearance while the inner construction carries the engineering requirements.
For compliance-sensitive projects, avoid selecting only by appearance or leaf thickness. The approving authority normally checks the full door set, including frame, hardware preparation and installation condition. Visfurn reviews the specification before quotation so the supplied build matches the certificate requested by the buyer.

Certification Guidance
Fire resistance, smoke control, acoustic performance and security resistance are not interchangeable claims. A rating accepted in one market may not be accepted by another project authority. Share the destination country, building type and approval requirement before pricing, and we will quote the construction that can be supplied against the correct certificate package.
- United States projects may require listed assemblies accepted by the local authority having jurisdiction.
- European projects usually review EN 1634-1 / local classification documents by full assembly.
- Other markets may require national standards, project consultant approval or third-party inspection.
Applications
Suitable for apartment entry doors, protected commercial entries, stairwell doors, service rooms and other openings where a robust steel assembly and documented project review are required.
Packaging & Shipping
Door leaves are protected with film, corner guards and export packaging. Matching steel frames and hardware cartons can be packed with the same shipment for easier site matching and project handover.
Frequently Asked Questions
Can you supply certified fire-rated steel doors?
Yes, but the exact build must be selected against the project certificate requirement. Fire-resistance builds are quoted after confirming destination market, approving authority, opening schedule and hardware.
Are fire resistance and security rating the same thing?
No. Fire resistance and burglary resistance are separate test systems. They should be reviewed independently so the project team does not rely on the wrong document.
Why is the frame supplied with the door leaf?
Fire and security performance depends on the full assembly, not only the slab. The steel frame, seal, hinge, lock preparation and installation condition all affect approval and site performance.
Can finishes and dimensions be customized?
Custom size, colour, woodgrain transfer finish, frame depth and hardware preparation can be reviewed against the selected certified build and batch quantity.
What information should buyers send first?
Send the door schedule, wall thickness, handing, lock and closer requirements, required standard or authority, quantity, destination and any consultant specification.
