Choosing a cleanroom door starts with the opening, not with the catalogue. List each opening with its function: personnel access, material transfer, equipment route, or viewing. Then assign a leaf arrangement from the brochure sizes: single-leaf at 800 or 950 mm, unequal-leaf at 1200 or 1350 mm, or double-leaf at 1500 or 1800 mm, all at a height of 2100 mm. An opening that falls outside those sizes is a custom size to confirm, not a size to approximate, because the leaf, the frame, the lock, and the sweep strip all follow the opening.
Next choose the door family. Steel panel doors lead with an aluminium alloy rounded-corner design, a shaft and shaft-sleeve arrangement described as dust-free in friction, a strong frame sealing strip, and a colour steel board described as impact resistant, not easily deformed, and easy to clean. Full steel doors lead with one-piece stamping and bending, a choice of spray-coated, colour-coated, or stainless steel board panels, a flanged snap-in window, and a customised Class A fireproof hexagonal aluminium honeycomb core. Both families share the leaf structure: 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. The family choice is therefore a choice of forming and panel character on top of a shared leaf, and the schedule should record both the family and the panel material.
Then choose the vision panel size per opening from 250 by 650 mm, 450 by 650 mm, or 400 by 600 mm, and record the lock and closer requirement per opening, noting that exact lock and closer types are subject to confirmation. For windows, the choice is simpler and should stay simple: a purification-grade aluminium alloy frame, PVC beading with desiccant beneath it to resist fogging, and toughened white glass stated as three to five times ordinary glass strength. Any window requirement outside that construction, such as a different frame material or a flush installation method, should be listed as a confirmation item rather than assumed.
Finally, list everything this guide marks for confirmation in the inquiry, in one list, so each item gets an explicit answer before ordering. That list includes sliding drive types, automatic mechanisms, roll-up arrangements, airlock interlock and pressure behaviour, walkable load figures, stainless steel window frames, flush installation methods, and access opening constructions. A guide that pretends those items are standard would mislead the buyer; a guide that names them as confirmation items lets the buyer order with the unknowns visible. Please confirm the minimum order quantity and the lead time in the same inquiry, because this site publishes neither figure.
- Step 1: list each opening by function, then assign a leaf arrangement from the brochure sizes.
- Step 2: choose steel panel or full steel family, and record the panel material.
- Step 3: choose the vision panel size per opening, and record lock and closer requirements.
- Step 4: for windows, confirm frame, beading with desiccant, and toughened glass per opening.
- Step 5: list every confirmation item explicitly in the inquiry, including drive, automation, interlock, load, and frame variants.
- Step 6: please confirm the minimum order quantity and the lead time in your inquiry.

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.
