Features of Inferior Stucco Embossed Aluminium Sheets
With technological development the stucco embossed aluminium sheet have become an indispensable material in various industries. However, not all people using the sheet believe in its quality, because there are so many inferior sheets in the market and bewildered consumers tend to be convinced by silver-tongued sellers. Then how to distinguish them? Features of inferior stucco embossed aluminium sheets include disqualified raw materials, insufficient chemical consumption and thin anodized film.
Disqualified raw materials refer to the fact that impure aluminium scraps are adopted in production, which will lead to wrong composition of the sheet and undoubtedly have serious negative result in its final application. As known to all, alloy aluminum sheets of different composition vary in properties. Impurities of undesired metals may greatly reduce the sheet’s critical properties. To reduce cost some stucco embossed aluminium sheet manufacturers reduce chemical consumption during the production process. This leads to decrease of corrosion resistance of the sheet. Manufacturers also focus on thickness of anodized film to reduce cost. They make the film thinner than 10um as said by the national standards. Anodized films of some inferior sheet under a previous inspection were only 2um thick! Others had no anodized film at all! Needless to say, such sheets are more vulnerable to corrosive materials.
In a word, inferior stucco embossed aluminium sheets are of lower cost. That’s why some manufacturers make every effort to convince buyers by low prices. No businessman would sell something lower than its cost, therefore, purchasers should be wary of unusually low prices.
