First: look at the anti-counterfeiting spray code. The profile of fengaluminum broken bridge aluminum will be printed with the anti-counterfeiting spray code of fengaluminum. However, it should be noted that there is no code spraying, or it is really Phoenix aluminum. Some fake Phoenix aluminum will also be printed with spray codes, but the spray codes of real Phoenix aluminum are difficult to scratch off. The fake Phoenix aluminum spray code is sprayed by the machine itself, and the ink is not good, which is easier to be wiped off.
Second: look at the color. When choosing the color, try to choose white or champagne, because only the two colors of white and champagne are the original color of fengaluminum factory. If you want other colors, such as spraying colors, you may be sprayed with other aluminum materials by bad merchants. Sell it to you as Phoenix aluminum broken bridge aluminum. The original White of the manufacturer has a gloss of Milky White, while the color of some fake products will be dazzling, which is not normal.
Third: look at the heat insulation strip of Phoenix aluminum profile. The insulation strip of the Broken Bridge aluminum profile will have the electronic code spraying of Phoenix aluminum.
Fourth: look at the lines on the surface of aluminum profiles. The surface of the aluminum profile produced by the factory is relatively flat without any trace. However, for the mixed brand of Phoenix aluminum, because there are many impurities in aluminum during processing, there will be uneven marks when extruded.
Fifth: look at his protective film. The real Phoenix aluminum protective film should also have a market identification phone. If there is no authenticity identification phone, it is also a fake sewing product.
