The door leaf is the unit a buyer actually orders, and its structure should be specified as a complete list rather than as a brand name or a single feature. The leaf described here has an aluminium door frame and an aluminium leaf frame, which together give the leaf its edge and its fixing line. The panel is colour-coated or melamine board, and the core is aluminium honeycomb, so the leaf combines a cleanable face with a light, stable interior. Internal stiffeners are built into the leaf to hold its shape over its life.
The lock is a rounded lock designed so it can be opened with the elbow, a detail that matters in cleanrooms where hands may be gloved, carrying, or required to stay clean. The sweep strip at the foot of the leaf is a double-spring rising type that settles smoothly, runs quietly, and seals well, giving the closed door its airtightness at the floor line. The hinges are stated to produce no metal powder over long use while remaining quiet and wear resistant, which protects the room from a slow contamination source that is easy to overlook in a specification.
The vision panel is an anti-fog double glazed toughened glass panel, so the leaf lets staff see through the door without opening it and without the panel fogging in use. Vision panel sizes are listed on the opening sizes page: 250 by 650 mm, 450 by 650 mm, and 400 by 600 mm, all as brochure dimensions. Locks and closers beyond the rounded lock itself are offered in multiple options, and the exact lock and closer types for a project are confirmed in the inquiry, because the product description does not itemise them by model.
Specifying a leaf means listing all of these parts together: frame, panel, core, stiffeners, lock, sweep strip, hinges, and vision panel. A schedule that names only the door family leaves the lock, the closer, and the vision panel size to chance, and those are exactly the parts that cause site queries. List them per opening, per leaf arrangement, and the leaf order can be checked before manufacture.

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.
