According to the requirements of GMP specifications, clean room design and installation should be considered when using to avoid the appearance of parts that are not easy to clean, so when cleaning decoration, cleaning air conditioning, doors and Windows installation and construction, all kinds of pipelines, lighting lamps and lanterns should be sealed.

The ground is self-levelled. Decoration should pay attention to the protection of the completed working surface, not due to impact, beating, trampling, water operation caused by plate sag, dark crack and surface decoration pollution. Choose the material with good air tightness and small deformation under the action of temperature and humidity.

Doors, Windows and inner walls should be flat and straight, and the structure should fully consider the sealing of air and water vapor, so that pollution particles are not easy to penetrate from the outside, and prevent condensation due to the temperature difference between indoor and outdoor. The amount of dust in construction should be controlled, especially the hidden space such as the ceiling and the inside of the clamped wall, which must be cleaned at any time. In the room with high efficiency filter installed, dust can not be carried out decoration work.
