Recently, the glass roof project of the Patent Office of the National Intellectual Property Administration in Zhengzhou, Henan, which was undertaken by Yanyi Group, has been successfully completed.

After various comparisons and references, the Patent Office of the National Intellectual Property Administration in Zhengzhou, Henan, ultimately trusted the quality and professionalism of Yanyi Group's doors, windows, and curtain walls, and chose our group to carry out the design and installation. The project department of Yanyi Group formulated a scientific, reasonable, and detailed construction plan. The on-site construction was carried out in an orderly manner, busy but not chaotic. At the same time, to ensure the safety and quality of the project, the project department prepared a separate, detailed, and feasible construction quality disclosure, safety plan, safety management plan, and safety risk assessment according to the actual on-site situation. Thanks to the trust and support of the client, this project was successfully completed in September.

Yanyi Group integrates the design, production, and installation of doors, windows, and curtain walls. The total area of Yanyi Group is approximately more than 500 mu. The company currently has thousands of employees. It has introduced tens of millions of yuan worth of advanced production lines, with a monthly output of up to 300,000 square meters. It also holds a number of patents and authoritative inspection reports. Currently, there are more than 300 exclusive stores and more than 400 franchise stores across the country, serving more than 129,000 end customers, whose presence can be found all over the country. The growth of Yanyi Group's doors and windows depends on the strong support and love of our customers. Thank you for being with us all the way!
