Hinged cleanroom doors are the default leaf arrangement for personnel doors, and their hinge is a cleanroom component in its own right rather than a commodity fitting. The product description states the hinge fact directly: over long use the hinges do not produce metal powder, and they remain quiet and wear resistant. In a cleanroom, metal powder from a wearing hinge is a contamination source that no cleaning schedule can fully excuse, so a hinge that holds that line over time is a genuine selection criterion, not a cosmetic one.
The hinged leaf around that hinge is the shared cleanroom 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, internal stiffeners, and an anti-fog double glazed toughened glass vision panel. The sweep strip matters as much as the hinge for a hinged leaf, because a hinged leaf meets the floor on a single line and the strip must settle smoothly, run quietly, and seal well every time the door closes.
When specifying hinged doors, list each opening with its leaf arrangement, its vision panel size, its lock and closer options, and its floor finish, because the sweep strip meets the floor and the hinge carries the leaf weight over its whole life. The brochure opening sizes for single-leaf doors are 800 mm and 950 mm wide with a height of 2100 mm, and unequal-leaf and double-leaf sizes are covered on their own pages so the schedules do not blur.

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.
