Top 10 Aluminum Window Manufacturers in China for Importers
Importers can use this evidence-based shortlist to begin supplier research, then verify the exact system, drawings, glass, hardware, performance documents, packaging and trade terms for their own order. The sequence is editorial, not a sales, market-share or quality ranking.
How We Selected These Companies
We reviewed public information available on 12 August 2026. Each company needed a name, a province-level location and an official page showing aluminum windows, window systems or direct window manufacturing. Inclusion does not certify commercial reliability. Import buyers must still verify the legal entity, factory, current certificates, product-specific test reports and contract terms. Rogenilan is the only Guangdong company selected in this particular editorial shortlist; that is a list-design rule, not a claim that Guangdong has only one window company.
This guide is published by Rogenilan, which is also included in the list. Every company is reviewed using the same publicly available location and product-relevance criteria. “Top” means an editorial shortlist for buyer research, not an independent market-share or sales ranking.
1. Rogenilan Windows and Doors
Foshan, Guangdong
Rogenilan’s official company page identifies a Foshan, Guangdong address and aluminum window and door manufacturing. Its public catalog covers casement, sliding, fixed, hung, specialty and electrically operated window systems. Buyers can inspect the company and location source and browse the aluminum window range.
Importer check: send a window schedule and request system-specific profile, glazing, hardware, finish, performance-document and packing confirmation. This article is hosted by Rogenilan, so buyers should apply the same independent due diligence used for every other entry.
2. LEAWOD Windows & Doors Group Co., Ltd.
Guanghan, Sichuan
LEAWOD’s official site gives factory addresses in Guanghan, Sichuan and presents aluminum thermal-break windows, timber-aluminum products and multiple opening modes. Its contact page verifies the Sichuan location, while the window page lists aluminum window systems.
Importer check: clarify which legal entity will invoice, which factory will produce, the exact aluminum or composite construction, and whether a quoted certificate and report cover the proposed size and configuration.
3. Shanghai Ruishi Window & Door Co., Ltd.
Shanghai Municipality
Ruishi’s official website locates the company in Tinglin Town, Jinshan District, Shanghai and describes manufacturing of architectural aluminum alloy windows, doors and curtain walls. The official company page also describes its project cooperation process.
Importer check: determine whether the offered system is proprietary or licensed, obtain authorization evidence where a third-party system brand is specified, and approve shop drawings, hardware, glass build-up and finish samples before production.
4. Superhouse
Shanghai Municipality
Superhouse’s official site identifies Shanghai as its base and presents aluminum windows, doors and curtain-wall products for overseas projects. The company history and address page and product overview provide the public evidence used here.
Importer check: ask for the exact report or listing that matches the quotation rather than relying on a general certification statement. Confirm glass sourcing, hardware substitutions, drainage, screens, spare parts and installation documentation.
5. Shanghai Finzone Windows & Doors Co., Ltd.
Shanghai Municipality
Finzone’s official profile provides a Shanghai address and describes a factory specializing in aluminum windows, balcony glazing and sliding or folding glass systems. See the official company and product profile.
Importer check: define whether the enquiry is for framed aluminum windows, frameless balcony glazing or another system. Confirm local-code suitability, safety glass, water management, guard requirements, panel parking, replacement parts and packaging.
6. Shanghai KEDO Industrial
Shanghai Municipality
KEDO’s official website places the company in Liantang Industrial Park, Qingpu, Shanghai and states that it designs and produces aluminum window systems, including sliding, commercial and bifold configurations. Review its official company and window-system page.
Importer check: treat customization statements as a starting point. Request written confirmation of attainable dimensions, structural limitations, glass weight, hardware loads, drainage, performance evidence and who owns the approved shop drawings.
7. Shanghai Zhijing Doors and Windows Co., Ltd.
Xuzhou, Jiangsu
The company’s official export site identifies Shanghai Zhijing Doors and Windows Co., Ltd., gives a Tongshan District, Xuzhou, Jiangsu location and describes thermal-break, sliding and other aluminum window systems. See its official company profile.
Importer check: verify the relationship between the company name and the Jiangsu production address, the contracting/export entity, and the specific factory responsible for fabrication. Approve drawings, bill of materials, QC checkpoints and export packing in the purchase contract.
8. Jiangyin Xinyuan Aluminum Co., Ltd.
Jiangyin, Jiangsu
Xinyuan’s official site locates the company in Jiangyin, Jiangsu and lists window-and-door products including sliding, inward-opening and insulating window systems. Its official company and Windows & Door page is the source used for inclusion.
Importer check: establish whether the quote covers profiles, fabricated windows or both. For finished windows, obtain fabrication drawings, corner and drainage details, glass and hardware specifications, assembly QC records and final packing scope.
9. Qingdao Leixin Decoration Co., Ltd.
Qingdao, Shandong
Leixin’s official website gives a Jiaozhou, Qingdao, Shandong address and identifies aluminum windows and doors among its principal products, with sliding and hung window examples. See the official company and product page.
Importer check: request the applicable certificate schedule and report, not only a logo or general claim. Cross-check the proposed frame, glass, hardware and maximum sizes against the exact tested configuration and destination-market requirements.
10. Qingdao Yangguang Curtain Wall and Door Window Engineering Co., Ltd.
Qingdao, Shandong
Yangguang’s official site names the company, gives a Qingdao, Shandong address and presents aluminum alloy, thermal-break, casement, panoramic and other window products. Review the official company and aluminum-window range.
Importer check: distinguish supply-only windows from an engineering scope. Confirm responsibility for calculations, drawings, anchors, perimeter interfaces, site measurements, installation, testing and any curtain-wall coordination.

Supplier Due Diligence for Import Buyers
Define the product before comparing prices
Issue the same RFQ pack to every candidate: opening schedule, elevations, inside/outside views, sizes, quantities, operating type, frame depth, thermal-break requirement, profile alloy and temper if prescribed, finish, glass build-up, insect screens and hardware functions. A square-metre price without an aligned bill of materials is not comparable.
Verify drawings and performance evidence
Request section drawings, drainage and pressure-equalization details, mullion and coupler conditions, maximum sash sizes, glass bite, reinforcement rules and installation interfaces. Where wind, water, air, thermal, acoustic, impact or fire performance matters, require a report number, issuing body, tested specimen and applicability statement for the proposed configuration.
Clarify OEM and ODM scope
Do not assume that “custom” means private labeling, new tooling or original system engineering. Ask separately about logo use, packaging artwork, hardware selection, profile dies, shop-drawing responsibility, prototype approval, sample cost, tooling ownership, exclusivity and control of later revisions.
Plan samples, inspection and packaging
Approve finish chips, hardware samples, glazing samples and a production sample where risk warrants it. Define inspection timing, tolerances, functional checks, glass labels, protection film, corner protection, crates or racks, desiccants, loading photographs and the method for reporting shortages or damage.
State logistics and commercial terms
Ask suppliers to quote the same Incoterm and named place, identify included export documentation, and state container assumptions. The contract should address payment milestones, drawing approval, change control, inspection, remedies, spare parts and document delivery. Independently verify the beneficiary account and any change request through a known contact channel.

FAQ
Does “Top 10” mean these companies lead China by sales?
No. It is an editorial shortlist based on publicly verifiable location and aluminum-window relevance. It is not a market-share, sales, capacity or independent quality ranking.
Why is Rogenilan the only Guangdong company listed?
That is a selection rule for this article. Rogenilan is the sole Guangdong company in this editorial shortlist; the statement does not describe the wider Guangdong market.
Can an official website prove a supplier is qualified?
No. It establishes a starting point for product and location research. Buyers should verify the legal entity, factory, bank account, reports, samples, references and contract before payment.
How should importers compare aluminum window quotations?
Compare an identical drawing and bill of materials, including frame, glass, hardware, finish, screens, accessories, packaging, documents and Incoterm. Record exclusions and substitutions explicitly.
What should buyers confirm about OEM or ODM?
Confirm whether the scope is labeling, packaging, configuration changes, new tooling or original engineering. Document tooling ownership, approval stages, drawings, testing responsibility and revision control.
Prepare Your China Aluminum Window Enquiry
