Top 10 Windows And Doors Manufacturers in China

China has become one of the most active supply bases for windows and doors, especially for aluminum windows, sliding doors, folding doors, system windows, and glass curtain wall projects. Trade data shows that global trade for aluminum doors, windows, frames, and thresholds reached about USD 6.37 billion in 2024, while China remained a major exporter in related metal door and window categories. 

For buyers searching for the top 10 windows and doors manufacturers in china, the real value is not only ranking names. A good manufacturer should provide stable production, project matching ability, material control, customization support, and after-sales response.

HEHEJIAN focuses on customized glass curtain walls and aluminum doors and windows. Its product range covers broken bridge aluminum windows, system windows, heavy-duty folding doors, panoramic sliding doors, and narrow-frame sliding doors. These products match residential, villa, hotel, commercial building, balcony enclosure, and engineering project needs.

One important strength of HEHEJIAN is its production foundation. The factory has more than 60 employees, including over 15 professional management team members. With a workshop area of over 6,000 square meters, professional curtain wall production lines, and two glue injection lines, the company can support both customized orders and project-based supply.

For window products, HEHEJIAN provides options such as outward opening broken bridge aluminum windows and six-track system windows. These designs focus on ventilation, clean views, sealing performance, and thermal insulation. For large openings, villas, and high-end residential spaces, panoramic sliding doors and heavy-duty folding doors help create wider views and better indoor-outdoor connection.

Quality control is also important when choosing a windows and doors manufacturer in China. HEHEJIAN follows a production process covering design, drawing, cutting, assembly, sealant injection, inspection, packaging, and delivery. The company also holds construction enterprise qualification and ISO9001 quality management certification, which helps project buyers evaluate supplier reliability before cooperation.

Another reason buyers compare China manufacturers is service capability. HEHEJIAN provides pre-sales consultation, site measurement support, solution design, quotation planning, technical communication, delivery acceptance, warranty support, repair response, and maintenance service. This makes the company more suitable for buyers who need project coordination rather than only standard products.

As energy-saving buildings, green materials, and customized architectural design continue to influence the market, buyers need a supplier that can balance appearance, performance, delivery, and long-term service. HEHEJIAN’s experience in aluminum windows, aluminum doors, and glass curtain wall manufacturing gives it a strong position for overseas project buyers looking for stable China-based supply.
