Surface finish is the face a cleanroom actually lives with, and for FFU blind panels the stated face options are three: PE coating, anti-static carbon-coated colour steel board, and 304 and 316 stainless steel anti-corrosion board. Each face should be chosen per room, because the room's cleaning regime, static control needs, and corrosion exposure differ, and a single face across a whole project is a convenience choice rather than a specification choice. Listing the face per ceiling field, on the same layout as the panel size and core, keeps that choice visible.
PE coating is the general face option in the stated list. Anti-static carbon-coated colour steel board is the face option for rooms where static control is part of the ceiling requirement, and its description as anti-static carbon-coated is stated as a face construction, not as a measured performance claim on this page. The 304 and 316 stainless steel anti-corrosion boards are the face options for rooms where corrosion resistance is the governing requirement. This page attaches no test conclusion, rating, or measurement to any of the three faces, because the product description lists the faces without giving test results for them.
Faces must not be confused with door panels. The stainless steel faces on this page belong to ceiling blind panels, while stainless steel board as a door panel belongs to full steel doors, and the two should never share a schedule line. A ceiling schedule should name the panel size, the core, and the face together per field, and a door schedule should name the door family and panel material per opening, so the factory never has to guess which stainless steel item a line refers to. Where a project needs a face outside the three stated options, confirm availability in the inquiry rather than assuming it.
- PE coating: general face option for FFU blind panels.
- Anti-static carbon-coated colour steel board: face option for static control needs, stated as construction, not as a measured claim here.
- 304 stainless steel anti-corrosion board: ceiling face option for corrosion exposure.
- 316 stainless steel anti-corrosion board: ceiling face option for corrosion exposure.
- Not door panels: these faces belong to ceiling blind panels only.
- No test conclusions: no rating or measurement is attached to any face on this page.

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.
