1.0.1 This code is formulated with a view to strengthening the quality management of construction work, unifying the acceptance of construction quality of aluminium structures and ensuring the engineering quality of aluminium structures.
1.0.2 This code is applicable to the acceptance of construction quality of aluminium structures such as frame structures, spatial grid structures, panels, curtain walls, etc.
1.0.3 The construction quality acceptance requirements in the engineering technical documents and contract agreement documents adopted in the construction of aluminium structures work shall not be less than the requirements of this code.
1.0.4 This Code shall be used together with the current national standard "Unified Standard for Constructional Quality Acceptance of Building Engineering" (GB 50300).
1.0.5 Besides the provisions of this code, the acceptance of construction quality of aluminium structures shall comply with the provisions of the relevant current national standards.
