Steel panel doors and full steel doors share most of their construction, and a fair comparison starts by naming what is shared before naming what differs. Both families use the shared leaf: aluminium door frame and aluminium leaf frame, colour-coated or melamine board panel, aluminium honeycomb core, rounded lock operable with the elbow, double-spring rising sweep strip, quiet wear-resistant hinges, internal stiffeners, and an anti-fog double glazed toughened glass vision panel. A buyer comparing the two families is therefore not comparing two different leaves; the buyer is comparing two family characters built on one leaf.
The steel panel character leads with the aluminium alloy rounded-corner design, the shaft and shaft-sleeve arrangement whose friction is described as dust-free, and the frame sealing strip stated to seal strongly with noise reduction and sound insulation. Its panel is colour steel board, described as impact resistant, not easily deformed, and easy to clean, and size customisation is supported. The full steel character leads with one-piece stamping and bending on imported Savanini equipment, a panel choice of spray-coated, colour-coated, or stainless steel board, a flanged snap-in window formed as one stable unit, and a customised Class A fireproof hexagonal aluminium honeycomb core.
No superiority conclusion is drawn on this page, because the product description does not rank the families. A corridor door that takes trolley impact and frequent cleaning may weigh the steel panel description more heavily, while a door that needs a stainless panel or a one-piece formed shell may weigh the full steel description more heavily, but those are project judgements for the buyer to make against the stated facts, not conclusions this page asserts. What this page does assert is the comparison table below, which keeps each fact attached to its family, and the shared leaf facts attached to both.
Scheduling advice follows the same discipline: schedule steel panel openings and full steel openings on separate lines, record the panel material per full steel opening, and record the vision panel size and lock and closer requirements per opening for both families. That way the factory schedule, the lock schedule, and the vision panel schedule all stay consistent, and the comparison on this page remains a decision aid rather than a source of schedule errors.
- Shared: aluminium frames, honeycomb core, elbow lock, rising sweep strip, quiet hinges, stiffeners, anti-fog vision panel.
- Steel panel leads: rounded corners, dust-free friction description, strong frame sealing, easy-clean colour steel board.
- Full steel leads: one-piece forming, three panel options, flanged snap-in window, Class A fireproof hexagonal honeycomb core.
- No ranking: no superiority conclusion is drawn where the product description gives none.
- Scheduling: separate lines per family, panel material per full steel opening, vision panel and lock lines per opening.
Side-by-side comparison
| Feature | Steel panel door | Full steel door |
|---|---|---|
| Forming | Aluminium alloy rounded-corner design | One-piece stamping and bending, Savanini equipment |
| Panel | Colour steel board: impact resistant, easy to clean | Spray-coated, colour-coated, or stainless steel board |
| Window | Anti-fog vision panel in the shared leaf | Flanged snap-in structure, one stable unit |
| Core | Aluminium honeycomb core in the shared leaf | Customised Class A fireproof hexagonal aluminium honeycomb |
| Sealing | Frame sealing strip: strong sealing, noise reduction | Shared leaf sealing: frame strip and rising sweep strip |
How to read the specifications on this page
Dimensions and construction details on this page follow the Lairun product description for the component family shown. Door opening sizes quoted on this site are brochure dimensions: they describe the opening sizes listed in the product brochure, and any non-standard size should be confirmed in the inquiry. Aluminium profile codes are listed by code only; no profile dimension is stated where the product description does not give one. Items that the product description does not specify are marked for inquiry confirmation rather than described as available options, so buyers are not led to assume a mechanism, a load figure, or a material variant that has not been evidenced.
What to put in your inquiry
Send the opening sizes you need, the leaf arrangement, the surface finish you prefer, and the ceiling layout where the components will be installed. State the quantities per size, the site conditions, and the delivery location so the component list can be checked line by line. Where this page lists an item as subject to confirmation, include that item explicitly in your message so it is answered before any order is placed. Please confirm the minimum order quantity and the lead time in your inquiry, because this site does not publish those figures. Certificates are available upon request; please ask for the documents you need and state which project they are for.
