View DetailsWHY jinjiang
It is the details you do not see that make windows and doors reliable for years. Four core safeguards protect the quiet and comfort of every home.
Multi-chamber thermal-break aluminum profiles + insulating Low-E glass help retain heat in winter and block heat in summer, reducing annual heating and cooling costs.
Triple sealing gaskets combined with insulating glass significantly reduce outdoor noise, helping homes near busy roads stay quieter.
Multi-point locking hardware provides smooth operation and reliable anti-pry protection, maintaining a smooth feel through more than 100,000 opening cycles.
Standardized production includes corner sealing, reinforced corner joints and individual testing of sealing and operation before shipment to prevent water and air leakage.

TESTIMONIALS
Every positive review reflects the peace of mind behind a well-made window or door.
Before replacing the windows, a road ran right below our home and the nighttime noise made it hard to sleep. Jinjiang’s technician measured everything carefully. After installation, the sound reduction was immediately noticeable, the sliding action was very smooth, and even our neighbors asked who did the work.
We added a sunroom to our balcony. From design to installation, it took around ten days. The installers worked neatly, cleaned everything thoroughly, and we tested it during rain with no leakage. Now the whole family loves having tea there.
We compared three suppliers. Jinjiang’s profile specifications and quotation were the clearest, with no hidden charges. The installers were professional and also showed us how to maintain the hardware. The after-sales follow-up was prompt as well.

Home / About Us
For 15 years, we have focused on one thing: making every window and door better, so every family can live with confidence and comfort.
OUR STORY
In 2010, Jinjiang Doors & Windows started as a small workshop. From contract manufacturing to building our own brand, we have followed one simple principle: get the unseen details right — profiles, glass, hardware and workmanship — and a strong reputation follows naturally.
Today, Jinjiang operates its own factory and standardized production lines. Our portfolio covers residential windows and doors, sunrooms and curtain-wall projects, with solutions delivered to owners across more than 300 residential developments nationwide.
MILESTONES
Step by step, we have built Jinjiang into what it is today.
Started from a small workshop near a residential community, specializing in aluminum window and door fabrication and installation.
Moved into our own facility and introduced CNC cutting and corner-assembly equipment, significantly improving capacity and precision.
Launched our system windows and doors line, upgrading from individual-unit fabrication to integrated whole-window system design.
Expanded service coverage to surrounding cities, with annual installations exceeding 3,000 units and after-sales service points established in parallel.
Introduced automated production lines and digital ordering systems, reducing lead times by 30%.
More than 20,000 families have been served, with customer referrals remaining among the strongest in the industry for three consecutive years.
OUR VALUES
Slogans may go on the wall; standards go into the product.
Every process has inspection standards: corner sealing, continuous gaskets and clear drainage, with each unit water-tested and operation-tested before shipment.
Every quotation item is clearly specified. Profiles, glass and hardware use stated materials — no inferior substitutions and no hidden charges.
We continuously follow system-window technology and new materials, making better products accessible to more families at more reasonable prices.
Standardized installation and responsive after-sales service are basic professional responsibilities — we stand behind every window and door we deliver.
