2017 aluminum building profile construction sampling pass rate of 94.6%

[Abstract]:
Recently, the AQSIQ announced on the 2017 aluminum profile building construction and decoration materials quality supervision of the national linkage spot checks. The spot checks covered
Recently, the AQSIQ announced on the 2017 aluminum profile building construction and decoration materials quality supervision of the national linkage spot checks. The spot checks covered 1768 batches of products (not involving export products) of 1768 enterprises in 29 provinces (autonomous regions and municipalities) in Beijing, Tianjin and Shanxi.
Building materials network
After testing, 1673 batches of 1673 batches of products qualified, 95 batches of 95 batches of products failed, the product pass rate was 94.6%, the detection rate of substandard products was 5.4%.
Among them, the aluminum profiles of construction were spot checks 416 batches of products of 416 enterprises in 19 provinces (autonomous regions and municipalities), the number of spot checks about half of the total number of manufacturing enterprises in the country, spot checks found 392 batches of qualified products, 24 batches Unqualified products, unqualified products detected rate of 5.8%.
The aluminum profile products spot checks and found that the aluminum alloy building profiles failed products mainly related to the project include: chemical composition, the nominal wall thickness, wall thickness deviation, the local oxide film thickness, the average film thickness oxide film, oxide film seal Hole quality, partial film thickness of the film, partial film thickness of the composite film, alkali resistance,
