GB/T 23444-2009 stipulates the relevant content of metal and metal composite ceiling panels. Clarify the product classification, and make requirements for Appearance mass such as surface flatness and color uniformity. Specify the dimensional deviation, mechanical properties (like tensile strength, bending performance) and functional indicators such as fire protection and moisture resistance. At the same time cover test methods, inspection rules, etc. This standard provides the basis for the production, quality control and market circulation of metal and metal composite ceiling panels, helping to ensure the mass of ceiling panels and meet the needs of architectural decoration.
