After the installation of each ceiling color plate, the color plate and keel need to be fixed with screws before the installation of the next color plate, and the gap between the plates should be filled as much as possible to ensure the clean room environment in the later period. Cross lines should be maintained at the joints between the four color plates to make them beautiful after gluing in the later period. For the roof seam where the wallboard is located, it can be used as the adjustment seam of the slab seam. By adjusting the roof seam in this area, the uniformity of the roof seam in other areas of the room can be ensured. The joint between the vertical wallboard and the roof shall be made of thickened angle aluminum or L aluminum as far as possible, and the fixing method shall be mainly screws (1.5cm large flat head drill tail screw is the best), and the fixing angles of safety doors, windows and doors shall not be fixed as far as possible, so as to facilitate the installation of door head adjusting plates and safety doors in the future.

During installation, the three-dimensional structures such as hangers, anchors and connectors between floor and ground shall be fixed first, and the garbage generated during construction shall be cleaned up in time. The surface of the ground must be smooth, and the seal at the junction with the vertical wallboard should be considered when brushing the surface. Before the partition wall is installed, the pay-off size must be strictly controlled, and the vertical transition angle should be strictly controlled to prevent the wallboard from tilting and twisting due to accumulated errors, and the vertical deviation of the partition wall should not be greater than 0.2%. The ceiling should be arched backward in the width direction of the room, so that the ceiling will remain flat during use after loading. Around the ceiling should be closely connected with the wall, and fixed with special aluminum trough or angle iron.

According to the characteristics of color steel plate, it is necessary to distinguish the construction scheme of color steel plate ceiling in the actual installation process. Not all materials have the same ceiling technology and need to be treated differently.
