Do you have a minimum order quantity (MOQ)?

Yes, the minimum order quantity for doors and windows is 7 sets. This is because it is also the lowest charge from freight companies, which ship at a rate of 1 cubic meter, approximately equivalent to 6 sets of doors.

AI-Powered supplier vetting

SummaryThe supplier is an aluminum-profile manufacturer based in Shandong, China, producing profiles for windows, doors, and industrial applications. It reports OEM service for well-known brands, customization options, six production lines, extrusion, painting, and oxidation facilities, and 11–20 quality-control staff. Written procedures and records exist for service assessment, corrective and preventive actions, and customer complaints. However, the supplier has no stated supplier-management-system certification, no available SDK, only one year of R&D engineer experience, and no overseas warehouses, showrooms, agents, branches, or offline trade-show participation. Export sales represent 31%–40% of total sales, while overseas service coverage is reported as zero. Financial information is represented only by years rather than financial results, so credibility cannot be determined.

Supplier typeThe supplier is identified as an aluminum-profile manufacturer specializing in window, door, and industrial sections. Its stated operations include extrusion molding, painting, and oxidation treatment, indicating a manufacturing supplier rather than a purely trading or service company.

CertificationsThe supplier-management-system certification field is explicitly recorded as NIL. No certification holding is evidenced in the provided information, but the record does not establish whether other product or process certifications exist.

After-Sales capabilityThe supplier has written procedures and followed records for service capability assessment, corrective and preventive actions, and customer complaints. However, it reports zero countries with overseas services and no overseas warehouse, showroom, agent, or branch, limiting demonstrated international after-sales coverage.

R&D capabilityThe supplier reports no available SDK and only one year of total R&D engineer experience. It does report an AI model for big-data processing and management decision support, but this does not sufficiently demonstrate strong product or engineering innovation capability.

Production capacityThe supplier operates six production lines, including extrusion molding, painting, and oxidation treatment, and has 11–20 quality-control staff. Its stated departmental structure includes production and quality-inspection functions, providing explicit evidence of established manufacturing capacity.

Customization capabilityThe supplier provides OEM services for well-known brands and offers customization for aluminum profiles used in windows, doors, and industrial applications. These statements directly support its ability to produce customized products.

Product Q&A

Q:Will there be any problems with the inside of the glass? For example, fogging or frost?

We usually use 5mm+6A+5mm double-glazed glass. You can rest assured that our double-glazed glass is professionally manufactured and will not fog or frost.

Q:Do all these doors and windows come with mounting frames?

Yes, all doors and windows include frames. The doors and windows can be directly installed on the wall.

Q:How do we guarantee product quality?

We always provide pre-production samples before mass production. We always conduct a final inspection before shipment.

Q:What are your packaging options?

We offer three packaging options: bubble bags, bubble bags + wooden frames, and bubble bags + wooden crates. For full container loads, we recommend using bubble bags, as this saves space and allows more goods to be packed in the same container. Normally, we choose bubble bags + wooden frames. The best packaging option is bubble bags + wooden crates. Some bulk cargoes, as well as goods from some developed countries such as the United States, Australia, and some European countries, require wooden
