Our History

Over more than a decade of development, the company has undergone numerous equipment upgrades and technological advancements. In 2015, it introduced its first fully automated tempered glass production line, doubling its production capacity. In 2018, a laminated glass production workshop was added, expanding the product portfolio from simple tempered glass to composite products such as laminated and insulating glass. In 2021, capitalizing on the trend toward energy-efficient architecture, the company launched a Low-E insulating glass production line, successfully entering the green building materials market. In 2023, the company further optimized its production processes and implemented a refined management system, achieving a stable product pass rate of over 98%.
To date, the company has served more than 500 domestic and international clients and participated in numerous key local projects, establishing a strong reputation and credibility within the glass processing industry of the Yangtze River Delta.

 

Our Factory

The company's production base is located at No. 777 Limin North Road, Lili Town, Wujiang District, Suzhou City. Situated within the Yangtze River Delta Integration Demonstration Zone and adjacent to the G50 Shanghai-Chongqing and G1522 Changshu-Taizhou expressways, the facility is just a one-hour drive from the Shanghai Hongqiao Transportation Hub, offering exceptional logistics and transportation convenience.

The factory covers a total area of ​​approximately 6,000 square meters, comprising about 4,000 square meters of production workshop space and 2,000 square meters for warehousing and offices. The workshop features a scientifically optimized layout divided into seven functional zones: raw glass storage, cutting and processing, tempering, laminating, insulating glass assembly, finished product inspection, and packaging/shipping. These zones are seamlessly integrated to ensure high production efficiency.

The factory employs a workforce of over 40 people; key technical and quality control personnel account for more than 30% of the staff, and employees in core positions possess over five years of experience in deep glass processing. Operating on a two-shift system, the facility boasts a daily production capacity of 2,000 square meters of tempered glass, 1,500 square meters of laminated glass, and 1,200 square meters of insulating glass, enabling it to meet supply demands for projects of all sizes.

The factory strictly implements the 6S on-site management system. Quality inspection checkpoints are established at every stage of the process-from raw material intake to finished product dispatch-ensuring that all products comply with national standards (such as GB/T 9963 and GB/T 15763.2) as well as international standards like the EU's EN 12150.
