Qianchuan Wooden Door's "New Universal Quick-Assembly Door and Window Frame" has obtained a national utility model patent

　　Recently, the "New Universal Adjustable Quick-Install Door and Window Frame," developed under the leadership of Luo Zhengren, a Chinese wood products expert and Chairman of Qianchuan Wooden Doors, was granted a utility model patent by the National Intellectual Property Administration of the People's Republic of China. This is another major technological invention in the wooden door industry, living up to Qianchuan Wooden Doors' reputation as a promoter of technological development in China's wooden door sector.

　　With the development of industrialization, prefabricated doors have entered the factory era. However, due to the inability to unify the dimensions of building openings, especially wall thickness standards, many inconveniences have been caused in the production and installation of wooden door frames. The currently used modular door frame component designs lack universality, cannot be adjusted on-site, have long production, transportation, and installation cycles, high costs, and it is difficult to achieve true industrialized, large-scale production and adapt to international market operations.

　　Facing this industry challenge, the Chairman of Qianchuan Wooden Doors has been considering whether it is possible to invent a more optimized universal adjustable quick-install door and window frame design that meets adjustment requirements. As early as 2006, he invented the "Quick Universal Adjustable Door Frame and Manufacturing Method," which achieved optimization effects such as adapting to standard wall thickness specifications, on-site adjustability for tolerance variations, cutting optimization, and short production, transportation, and installation cycles. However, it still could not meet the requirements of a large number of non-standard walls. After years of careful research and experimentation, a "New Universal Adjustable Quick-Install Door and Window Frame" was finally invented.

　　The "New Universal Adjustable Quick-Install Door Frame" can provide a solution that meets the adjustment requirements for the many existing standard and non-standard wall thickness specifications and manufacturing tolerance-induced wall thickness differences; it also achieves short product production cycles, high product quality, convenient and easy installation, and environmentally friendly manufacturing. This will be a groundbreaking innovation for the industry, greatly impacting the wooden door sector and truly enabling the industrialized and large-scale development of the wooden door industry.

　　Innovation is the inexhaustible driving force for enterprise development and is also the key to promoting industry progress and leaps. Qianchuan Wooden Doors has always adhered to strong responsibility and commitment, continuously innovating and surpassing itself, leading the industry toward more technological and advanced directions.
