Profile families are best understood by the joint or edge each family serves. Channel aluminium and middle aluminium serve panel joints: the channel receives a panel edge, and the middle joins two panels in a run. Outer arc profiles finish external corners with a rounded line that is easier to clean than a sharp corner. Window aluminium frames the cleanroom window, and T beams carry the ceiling grid into which blind panels are set. Special profiles are made for particular uses that the standard families do not cover, and they should be described by use in the inquiry rather than by an invented code.
The codes recorded for this range are JH001A, JH009, JH025, JH010, JH011B, JH039, JH006D, JH014B, JH024, JH022, JH164, and JH258. They are listed by code only throughout this site, because the product description records the codes without giving a dimension for each one. A buyer who needs a dimension for a code should send the code with the application and the required length, and confirm the section against the code, rather than reading a dimension from another family's page or from a generic profile table.
Families are not separate thin pages on this site, by design. A single families page lets a buyer compare the joint, corner, window, and ceiling roles side by side, and lets a schedule list the family, the code, the quantity, and the length on one line per section. Where a project needs profiles for walls, doors, windows, and ceilings together, send one profile schedule that groups sections by the family page they serve, so the supplier can check the whole joining system at once. The diagram below is a structural exploded diagram, not a finished product photograph, and it shows how a panel, a core, a profile, and a corner piece relate in an assembly.
One caution applies to every family: profile dimensions, wall thicknesses, and lengths are not stated on this site, and no dimension should be copied from a drawing, a listing, or another supplier's table into an order for these codes. Confirm the section by code and by application in the inquiry, and the order will rest on the code that was actually confirmed.
- Channel aluminium: panel edge and joint family.
- Middle aluminium: panel-to-panel joint family.
- Outer arc: external corner finish family.
- Window aluminium: cleanroom window frame family.
- T beams: ceiling grid family for blind panels.
- Special profiles: particular uses, described by use in the inquiry.

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.
