This guide covers roll-up doors as a selection question, not as a product on this site. No roll-up door product is stated in the product description used for this site, and no roll-up mechanism, opening speed, curtain material, or size is stated here. A buyer who arrives searching for a roll-up door should therefore read this guide as a map of the question: what a roll-up door would need to do, how it compares with the door families that are stated, and what to ask before assuming one can be supplied.
Roll-up doors are usually considered where a door must open and close frequently, where headroom or side space is limited, or where a fast cycle is wanted between rooms. Those are legitimate operating requirements, and they should be stated in the inquiry in those terms: cycle frequency, clear opening, headroom available, side space available, and any sealing or airtightness requirement at the closed position. Stating the operating requirement, rather than naming a product type and assuming it exists, lets the supplier answer the real question, which is whether the requirement can be met and with what construction.
For comparison, the stated door families on this site are steel panel doors and full steel doors on a shared leaf: aluminium frames, honeycomb core, elbow-operable rounded lock, double-spring rising sweep strip, quiet wear-resistant hinges, stiffeners, and an anti-fog double glazed toughened glass vision panel, with brochure opening sizes from 800 mm single-leaf to 1800 mm double-leaf at a height of 2100 mm. A buyer comparing a roll-up idea against those families should compare cycle frequency, sealing at the closed position, vision provision, and maintenance access, because a roll-up curtain and a rigid leaf differ on all four, and the comparison should be made on operating facts rather than on a product name.
Related search terms for this guide include high speed doors and speed doors for clean rooms, which are treated the same way: as selection questions whose availability and specification are subject to inquiry confirmation. Until a roll-up or high speed arrangement is confirmed for a specific opening, the safe specification is a stated door family from the door pages, with the roll-up requirement recorded as an open inquiry item. Please confirm the minimum order quantity and the lead time in the same inquiry, because this site publishes neither figure.

Roll-up selection questions
| Question | Why it matters |
|---|---|
| Cycle frequency | Determines whether a rigid leaf or a roll-up cycle suits the opening |
| Clear opening and space | Headroom and side space constrain the arrangement |
| Closed sealing | Sealing at the closed position must be confirmed, not assumed |
| Vision and maintenance | Vision provision and access differ between curtain and leaf |
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.
