Apparently, each manufacturer's invisible aluminum guardrails seem to be the same in shape. The difference between them is very large. To carefully compare the materials and materials of invisible aluminum guardrails, you can distinguish between good and bad.

2, look at the thickness of the profile: aluminum alloy support steel wire, to withstand the huge tensile force of the steel wire, its thickness judges the strength of the entire invisible aluminum guardrail

3, look at the accessories used to fasten the steel wire, this is the key to judging the quality, this part is not easy to be found, the user is invisible when looking at the sample window, so the user is the best condition when looking at the sample Take a piece of information and see the layout inside.

6. Check the flatness of the surface of the profile, such as a hollow profile, and see if there are any depressions or bulges on the four sides.

7. Check the surface of the profile for open air bubbles (white dots) and ash (black dots).

8. No cracks, burrs, peeling or corrosion are allowed on the surface of the profile. The surface of the profile is not allowed to have obvious scratches, craters and bumps.

10, put a few profiles together, look at the color difference, such as large color difference, not easy to use.

11. Use a smooth hard object (iron) on the surface of the profile, and draw a light stroke. Leave a white scratch on the surface of the profile. If it can be wiped off by hand, it means that the oxide film is not wiped off. When the oxide film has been removed, the oxide film is poorly fixed, the oxide film is too thin, and the aluminum oxide is poor in oxidation quality.
