Opening & handing
Structural opening, finished door size, wall condition, handing, single/double leaf and threshold.
Functional steel doorsets
Steel Service Doors.
Evidence Before Claims.
Functional steel door programs for utility, back-of-house, commercial and security applications. Any fire, acoustic or other rating is offered only through an exact, valid and destination-accepted assembly route.
Procurement boundary
A door image cannot carry a rating.
Performance belongs to the complete doorset and installation conditions, not to the core or leaf image alone. Leaf, frame, seals, glazing, hardware and field installation must remain within the exact tested, listed or otherwise accepted configuration.
LANDO does not market an unverified fire rating. Where suitable evidence is unavailable, we quote the product only as a non-rated steel service doorset.

Visual directions
Service and steel-door starting points.
These images support design discussion only. They do not represent a tested rating. Send the destination, opening and performance requirement for a valid sourcing review.
Minimum brief
Define the doorset, not only the leaf.
Steel service doors and fire-resistant assemblies require an opening-level schedule and a disciplined hardware/evidence review.
Leaf & frame
Steel material and thickness, reinforcement, core, frame profile, anchors and finish system.
Hardware set
Hinges, lock, panic hardware, closer, coordinator, seals, glazing and factory preparation.
Evidence & installation
Destination code, accepted test/listing route, field installation, labels and documentation.
Current supply policy
Fire-resistant doors are not a default catalog line.
LANDO will first check whether the selected manufacturing route has current evidence for the exact assembly and whether that evidence is accepted by the destination authority, consultant or buyer.
- No rating inferred from domestic product descriptions
- No substitution of core, frame, hardware or seals outside evidence
- No claim based only on a supplier relationship or previous project
- Written approval route before deposit where performance is contractual
