Certificates for the components on this site are available upon request. That is the complete certificate statement this site makes: it does not publish a certificate number, an issuing body, a scope, or an expiry date for any certificate, and no such detail should be inferred from any product description, listing, or third-party page. If your project needs documents, ask for them by name in your inquiry and state which project they are for, so the correct documents can be supplied for that project.
This restraint is deliberate. Certificate details belong to the document itself, and publishing a number or a body without the document in hand would turn a requestable document into an unverified claim. The same restraint applies to test reports and to any product performance claim that would normally be evidenced by a document: where this site states a performance fact, it states the fact as given in the product description, and where a document is the evidence, the document is requested rather than summarised.
When you request certificates, include the component families in your order, the project location, and any document format your project requires, such as a copy for a submittal package or a copy for a client file. Please also confirm the minimum order quantity and the lead time in the same inquiry, because this site publishes neither figure. Send certificate requests to [email protected] or call +86 13929918930.

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.
