This site covers the component families that complete a cleanroom envelope: doors, windows, ceiling blind panels, and the aluminium profiles that join them. Foshan Lairun New Building Materials Co., Ltd. is based at the Nanhai National Eco-Industrial Park in Danzao Town, Foshan, Guangdong, and its public product range includes cleanroom doors, double glazed windows, FFU handmade blind panels for ceilings, and purification aluminium profiles. Each family is presented here as a set of components with stated construction facts, so a buyer can compare leaf construction, glazing, ceiling panel cores and finishes, and profile codes before sending an inquiry.
Doors are the most detailed family on this site. The range includes steel panel doors and full steel doors, with a shared leaf structure built around an aluminium door frame and an aluminium leaf frame, a honeycomb core, a rounded lock that can be operated with the elbow, a double-spring rising sweep strip, hinges, internal stiffeners, and an anti-fog double glazed toughened glass vision panel. Steel panel doors use an aluminium alloy rounded-corner design with a shaft and shaft-sleeve arrangement described as dust-free in friction, while full steel doors are formed by one-piece stamping and bending on imported Savanini equipment. Panel options for full steel doors include spray-coated board, colour-coated board, and stainless steel board.
Windows on this site are double glazed cleanroom windows with a purification-grade aluminium alloy frame, PVC beading with desiccant beneath it to absorb moisture and resist fogging, and toughened white glass. Ceiling panels are FFU handmade blind panels that close a cleanroom ceiling, block air movement, and help keep dust and bacteria out of the cleanroom. Their cores are gypsum, magnesium board, or aluminium honeycomb, and their faces can be PE coating, anti-static carbon-coated colour steel board, or 304 and 316 stainless steel anti-corrosion board. Aluminium profiles cover channel aluminium, middle aluminium, outer arc, window aluminium, T beams, and special profiles for particular uses, listed by JH code only.
- Door families: steel panel doors, full steel doors, and the shared leaf structure, locks, closers, vision panels and sealing system.
- Window family: double glazed cleanroom windows with desiccant-backed beading and toughened glass.
- Ceiling system: FFU blind panels, surface finishes, grid and access, and installation nodes.
- Profile families: channel, middle, outer arc, window and T profiles, plus special profiles, by JH code.
- Guides: how to choose doors and windows, a steel panel versus full steel comparison, and a semiconductor ceiling application guide.

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.
