9 standards for ceiling acceptance

The guidelines provided here are applicable for the installation and acceptance of various ceiling projects, including those with wooden, light steel, or aluminum alloy keels as frameworks, and ceilings covered with different materials like gypsum boards, plywood, glass, or PVC buckle panels. Take a look at this image showcasing a finished ceiling project:  1. The materials used in the ceiling project, including their types, specifications, colors, basic structural designs, and fixing methods, must adhere to the design specifications. 2. All types of keel ceilings need to be securely installed. Post-installation, a thorough inspection and leveling should be conducted to ensure the correct positioning. 3. Wooden frames should use timber that meets the design requirements. Each piece of wood should be glued and nailed securely, while the side in contact with the cover panel must be smoothed out. 4. The wooden framework of the ceiling should comply with fire safety regulations. 5. Various cover panels should be free from bubbles, peeling, cracks, chipped corners, dirt, or pattern defects. The surface should be smooth, edges sharp, and color uniform. 6. For perforated plates, the hole arrangement should be neat. Concrete and wood fiberboards should not exhibit delamination, discoloration, or decay after being glued. 7. When using plywood or medium-density fiberboard secured with nails, the nail spacing should be between 80-120mm, with nail lengths of 25-35mm. The nail heads should be flush with the surface, sinking into the board by about 0.5-1mm, and covered with an oily putty. 8. If the veneer surface is treated with varnish, the grain and color of adjacent panels should match closely. 9. When applying coatings or paint to the cover panels, joints should first be brushed with white glue and pressed with fine cotton cloth. The overlapping seams should extend at least 5cm on both sides. In addition to these technical aspects, it’s crucial to understand the broader context of integrated ceiling systems. These systems often involve combinations of glass, paint, and aluminum alloy components, each playing a specific role in achieving both aesthetic and functional goals. Understanding the interplay between these elements is key to ensuring high-quality results in ceiling installations. While following these guidelines, always remember that the final product should reflect attention to detail and quality craftsmanship. Whether you're working with glass, paint, or aluminum alloy components, every step should contribute to creating a ceiling that is not only visually appealing but also durable and safe.
