LPSK Authenticity Identification Method.

1. Look at the wall thickness. The minimum measured wall thickness of the aluminum profile without surface treatment of the main stressed member is not less than that of the door and the window. 2. Chromaticity:

The color of the same aluminum alloy profile should be consistent. 3. Flatness: Check the surface of the aluminum alloy profile, there should be no depression or bulge.

4. Gloss: Aluminum alloy doors and windows should avoid buying profiles with obvious defects such as open bubbles (white spots) and ash slag (black spots) on the surface, as well as cracks, burrs, and peeling. 5. Degree of oxidation:

The thickness of the oxide film should reach 10 microns. When purchasing, you can scratch the surface of the profile to see if the oxide film on the surface can be wiped off The above is the profile.

Hello, I have inquired for you.

**And how to look at defective products.

Hello, the method I sent you above. If you follow what I said above, it's **. If not, it's defective.

Isn't there a spray on LPSK's material now?

There is a "LPSK" computer inkjet code every one meter three on the "LPSK" aluminum. At the same time, with the banknote detection light (i.e., ultraviolet light), you can see the anti-counterfeiting mark of the word "LPSK". All of them have a production date**.

You can only see it with a banknote detector light.

There's nothing on it, isn't it?

It must be fake.

There is no coding for Lu Cai.

No coding is fake.

How much is the manufacturer**.

Okay, I'll check it out for you right away, please wait.
