1. Look at the brand code. There will be brand inkjet codes on aluminum materials, whether they are true or false, they will be marked with a logo. Real inkjet codes are generally difficult to scratch off, while fake inkjet codes are easier to be wiped.

Lose.

Second, look at the shape of the profile. Nowadays, the colors of broken bridge aluminum doors and windows are very rich, and you can arbitrarily match the color and style of the home decoration. However, white broken bridge aluminum doors and windows are mostly used. For Zhenfeng aluminum, the original factory only has white and champagne colors. If there are other colors, they are sprayed separately by the processor. At the same time, the white of Zhenfeng aluminum is available

Milky white gloss, the color of many fake phoenix aluminum is pale white, without luster and texture.
