VISFURN is the project-door brand of Tianjin Visfurn Furniture Co., Ltd. This guide supports buyers comparing door packages, specifications and quotation scope.
Steel Security Door Systems
Steel entry door sets for apartments, offices and commercial openings, reviewed around frame, lock, hinge, finish and site specification requirements.
VISFURN reviews steel security door inquiries according to project opening size, door leaf construction, frame depth, hardware preparation, finish color and packing requirements. Any special performance requirement should be confirmed through the project specification before quotation.
Buyer Answer
Steel security doors should be reviewed by opening size, frame depth, lock direction, fire rating or certificate requirement, security hardware and finish color. If a project requires tested performance documents, confirm the target market and standard before quotation.
Buyer Answer
Buyers should verify the complete tested door-and-frame scope, requested fire duration, destination-market standard, hardware, seals, wall condition and supporting documents before ordering. VISFURN reviews these inputs against the requested steel door configuration; certification is specified per project, not assumed from the door leaf alone.

Yes. Fire rating or certification requirements should be stated in the project specification so the product scope can be reviewed against the needed standard and documents.
Send drawings, quantity, finish direction, hardware list and destination port so the steel security door package can be quoted accurately.
Confirm the required performance documentation, door-and-frame assembly scope, opening size, wall construction, hardware, seals, handing, finish and market-specific project requirements. Do not treat a leaf-only quote as a tested-set approval.
For fire-rated and security projects, buyers should usually define the complete opening set: leaf, frame, hinges, lock, closer, seals, threshold and fixing method. Changing components after quotation may affect rating or security performance.
Send the required fire rating duration, local market standard, opening size range, wall type and hardware schedule. VISFURN can then review whether the requested door scope matches available documents.
Specify lock body, cylinder grade, hinge type, anti-pry edge, frame depth and installation substrate. Photos or drawings of the project security target help avoid under-specification.
Confirm corner protection, palletizing, door number labels and mixed-container separation because steel frames and door leaves can be damaged if hardware and edges are not protected.
Fireproof steel doors, steel fire door systems and metal fireproof door sets should be specified with the frame, hinges, lock preparation, finish and verified performance documentation. Interior security door requirements can be reviewed separately from the project fire-rating scope before quotation.
Project-specific documentation
Where a project requires fire, security or certification documentation, provide the project location, requested standard, door-and-frame configuration, wall condition, hardware, seals and required document scope. Requirements must be reviewed against the selected configuration; this collection does not represent a blanket certification or performance approval for every door set.
