The cleanroom ceiling grid is the frame that makes blind panels work as a system. The grid member named in the purification aluminium profile family is the T beam, and the joint named for this ceiling is the blind panel ceiling joint. Together they form the ceiling plane into which FFU blind panels are set: the T beam carries the grid lines, and the blind panels fill the fields between them, with FFU openings scheduled in the same layout.
Handling is part of the grid story. Handmade panels in this range are described as easy to remove and refit, which matters above a cleanroom because filters, services, and ceiling voids all need access over the life of the room. The exact access opening construction is not itemised in the product description, so this page does not describe a hatch detail as standard; buyers who need defined access openings should list them in the inquiry with their positions on the ceiling layout, and confirm the construction before ordering.
Grid and panel schedules should be sent together. A ceiling layout that marks FFU positions, blind panel fields, and access positions lets the supplier check panel sizes against grid modules before manufacture, and avoids the common failure where panels and grid are ordered from different schedules and meet on site with a module mismatch. Panel sizes of 1175 by 1175 mm and 575 by 575 mm should be checked against the grid module on the same drawing.
- Grid member: T beam, from the purification aluminium profile family.
- Joint: blind panel ceiling joint.
- Handling: panels described as easy to remove and refit.
- Access openings: exact construction subject to inquiry confirmation; mark positions on the ceiling layout.
- Coordination: send grid module, panel sizes, and FFU positions on one layout.

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.
