GMP, standing for GOOD MANUFACTURING PRACTICES, translates in Chinese as "production quality management norms," "good practice specifications," or "good manufacturing standards." GMP is a mandatory standard framework for pharmaceutical, food, and related industries, requiring enterprises to supervise raw materials, personnel, facilities and equipment, production processes, packaging, and transportation, quality control, and related factors to satisfy sanitary quality standards per applicable national laws and regulations. These operational practices help enterprises enhance their workplace hygiene environment and promptly identify and rectify problems during the production process.

For the clean room, Article 49 stipulates that the inner surface (cleanroom wall, cleanroom floor, cleanroom ceiling) of the clean area should be smooth and flat, crack-free, with tight seams, shedding no particles, preventing dust accumulation, and easy to clean and disinfect when necessary.

The common clean room is the connection between the cleanroom wall panel and the aluminum profile to form a closed clean room. However, due to the significant thermal bridge of standard corner panels, dust easily accumulates at the contact joint between the aluminum profile and the panel. In addition, cleaning and disinfection are inconvenient, which is the primary reason dust frequently gathers at corners and louvers in everyday environments.

To resolve these industry challenges, Cnsterilezoom has developed the integrated One Piece Cleanroom Corner Systems (has applied for national patent), L-shaped one piece cleanroom corner, T-shaped cleanroom corner, L-shaped cleanroom corner and T-shaped cleanroom corner composed of return air column.

Compared with our patented product integrated corner plate, it is evident that forming the panel into an integral corner plate ensures a smooth, seamless corner without crack transitions, a tighter interface, and no air leakage. The overall corner angle also features increased thickness at the corner position.

Thermal analysis demonstrates that once the complete corner is formed, the thermal bridge phenomenon is effectively eliminated, achieving a smooth and seamless transition.
