Use this page to assemble a component inquiry that can be answered without a round of clarifying questions. Start with the component family: doors, windows, ceiling panels, or profiles. Then give the schedule: for doors, each opening with its leaf arrangement, width, height, vision panel size, and lock and closer requirements; for windows, each opening size and wall; for ceilings, the layout with FFU positions, panel size, core, and face; for profiles, the JH codes with quantities and lengths. A schedule sent in that form can be checked line by line against the stated facts on this site.
Then list every item this site marks for confirmation, in your own words, so each one gets an explicit answer. That list may include a sliding drive type, an automatic mechanism, a roll-up arrangement, an airlock interlock or pressure behaviour, a walkable load figure, a stainless steel window frame variant, a flush installation method, an access opening construction, a special profile dimension, or a non-standard door or panel size. Naming those items explicitly is not a formality: it is how a buyer avoids ordering a component on the assumption that an unconfirmed option is standard.
Please confirm the minimum order quantity and the lead time in your inquiry. This site deliberately publishes neither figure, and no figure should be inferred from any other page, listing, or third-party snippet. Certificates are available upon request; if your project needs documents, state which documents and which project they are for. Send your inquiry to official@lairungroup.com or call +86 13929918930, and keep the schedule, the confirmation list, and the project location together in one message.
- Step 1: name the component family and send the schedule.
- Step 2: list every item marked for confirmation, explicitly.
- Step 3: please confirm the minimum order quantity and the lead time in your inquiry.
- Step 4: for documents, state which certificates you need and which project they are for.

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.
