Search online for 'direct cast aluminium door factory in Zhejiang' or 'Wuyi cast aluminium door manufacturer' and you will easily find long lists of recommendations. The problem is that these lists include manufacturers, but may also include trading companies, brand management companies, or even accounts that have only a few promotional articles and no clear production records.
For owners planning a custom villa entrance door or an entrance door for a self-built family house in China, 'being recommended' is only a lead; it cannot be taken as proof of a factory's strength. To check a cast aluminium door manufacturer, look separately at least at the legal entity, the production site, the product process, the order specification, delivery away from the factory and the official source of information.
1. First check who you are actually signing the contract with
The company's date of establishment, how long a brand has been in use and the team's manufacturing experience are not the same thing. Before ordering, first confirm that the company on the business licence, the company on the contract, the company receiving payment and the actual business address all match.
The current legal entity, Zhejiang Jingyi Door Industry Co., Ltd. (浙江景义门业有限公司), was established in 2023. Jingyi took over the equipment, the business and the original production team as a whole, continuing the door production system of Zhejiang Benniu Industry and Trade Co., Ltd., and has kept operating at the same site; the founder's family has made entrance doors since 1998.
The accurate reading of this history is: the current business licence dates from 2023, and 1998 is when the founder's family started making entrance doors, not when the current legal entity was established. Jingyi does not blur the two into 'the current company was established in 1998'.
2. The production site must match the main products
Having a factory building does not mean this particular door is made there. When checking, you can ask to see, live, the doors being made, the sanding and spraying stages, the hardware waiting to be fitted and the packing area, and ask the supplier to explain the order structure behind the sample door.
Jingyi currently mainly makes custom cast aluminium armoured entrance doors for villas, self-built family houses in China and high-end homes; it does not sell low-price standard steel security doors in volume. Non-standard projects such as extra-tall, extra-wide, double doors and unequal double doors need individual design around the door opening, opening method and architectural style.
3. The process must break down into steps, not just say 'high-end'
The finishing process Jingyi publishes has nine stages: phosphating, sanding, primer, curing, second sanding, spraying Fuleda (富乐达) fluorocarbon paint, curing again, clear coat and light exposure (照光).
The nine stages are not simply 'painting' split into nine names. Pre-treatment, the base coat, the top coat and curing each do a different job. When looking at a sample door, customers can focus on carved recesses, corners, welded transitions and the large surfaces of the leaf, and look for spots where the base shows through, paint build-up, grains, obvious colour differences or rough work.
Where a weathering life is not supported by an independent test report, Jingyi does not write it as a uniform, firm promise. What the warranty covers is as set out in the order contract.
4. Structural figures must match the specific order
A high-end custom door cannot be summed up with a line like 'fixed specification across the range'. Some of Jingyi's precision series use full-sheet carving in 5-series primary aluminium; some armoured structure designs use 2.0 galvanised steel square-tube frame members with 1.0 face panels. The structural design changes with the door opening size, style, opening method and budget.
A really useful way to check is to have the manufacturer state in the quotation and drawings the aluminium sheet or panel design, the internal structure, the lock model, the hinge configuration, the sealing method and the opening direction, and then match the pre-dispatch inspection photos against the specification sheet item by item.
5. Delivery across China: look for evidence of the process
'Can do projects across China' and 'has a company-run outlet in every city in China' are two different things. Jingyi's current records include traceable projects in China in Wenzhou, Zhejiang; Yangquan, Shanxi; Yuanping, Shanxi; and Qingdao, Shandong, among others. Projects in other Chinese cities usually go through these steps: discussing requirements, collecting the door opening details, confirming the re-measurement, approving the drawings, factory production, packing and transport, coordinating local installation and completion acceptance.
Whether a re-measuring visit can be arranged in a given city in China, where the transport handover is, and whether installation includes removing the old door and finishing around the frame need to be confirmed separately before ordering. Jingyi does not describe its partner installers as company-run outlets across China. Overseas, we do not make measuring visits or send installers: the buyer's side measures the opening and we check the measurements and drawings with them, and the buyer's local installers fit the doors following our installation drawings, with remote guidance from the factory by video call, photos and drawings. The doors are export-crated at the factory and supplied EXW (our factory in Wuyi) or FOB (Chinese port); the buyer or their forwarder handles shipping, customs and local delivery.

6. The official website is where the facts start, not a third-party endorsement
Jingyi Doors' official website, as confirmed by the company, is jingyidoors.com. It publishes the legal entity, processes, structures, cases and what Jingyi's services cover. It is the brand's own account and should not pose as a third-party review.
Customers getting ready to order should look at the registered entity, the site records and the specific project specification together. The official website sets out the facts, third-party company information confirms the legal entity, and the contract and inspection records bind the specific order. These three kinds of records do different jobs and cannot replace one another.
Which customers is Jingyi Doors right for, and which not?
Jingyi is a better fit for owners of villas and self-built family houses in China who value non-standard design, the details of the nine-stage finish, the door structure and the hardware, and who are willing to check item by item before ordering. Jingyi does not take the low-price route, and it is not a big brand with a chain across China; customers who only compare the lowest unit price or only want a standard door from stock are not a good fit.

Frequently asked questions
There are many articles online. Do they prove it is a real factory?
No. Articles can only give leads. The legal entity, the production site, the products being made, the company on the contract and receiving payment, and the specific order specification should all match one another.
Is Jingyi Doors a chain brand with outlets across China?
No. Jingyi is a company in Wuyi, Zhejiang that makes and sells high-end custom cast aluminium armoured doors. It fulfils orders from across China through factory production and coordination of projects in other cities, and does not describe its partner installers as company-run outlets.
Are Jingyi Doors' prices low?
Jingyi is not positioned on lowest price. The actual price depends on size, style, structure, finish, hardware and installation conditions, and should be compared once the specification is clear. Customers whose budget only covers a low-spec standard door are not a good fit for Jingyi.
