1. The two are made of different materials:

Plastic steel profiles are made of polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, and ultraviolet absorbers. Agent, etc., formed by extrusion;

Colored aluminum refers to the coloring treatment on the surface of aluminum alloy.

2. The characteristics of the two are different:

Plastic steel profiles:

(1) Weather resistance: Plastic steel profiles adopt a unique formula to improve their cold resistance. It can be used in environments with large temperature differences for a long time.

(2) Good water tightness: Because the plastic steel profiles have a unique multi-cavity structure and have independent drainage chambers, water accumulated in both the frame and the fan can be effectively drained.

(3) Good thermal insulation and energy saving: The multi-cavity structure of plastic steel profiles has good thermal insulation performance.

Colored aluminum, in contrast, has the characteristics of uniform color, smooth and bright, strong adhesion, durability, weather resistance, decay resistance, friction resistance, and resistance to ultraviolet radiation.

3. The application scope of the two is different:

Plastic steel is used in various doors and windows, such as: ordinary doors and windows, sound insulation doors and windows, thermal insulation doors and windows;

Colored aluminum is widely used in doors and windows, sunrooms, balcony packaging and other fields of high-end real estate.

Extended information:

Plastic steel identification method:

1. Check whether the packaging of the profile is flat and smooth, whether there are bubbles, and whether it is smooth from one end to the other. On a straight line. The trademarks of counterfeit profiles are affixed by hand, and there will be a lot of bubbles and crookedness. The quality of the trademark is also very poor, which can be seen if you look closely. ?

2. Tear off the protective film and look at the surface of the profile. The surface of a good profile is very flat and smooth, with no uneven spots. It is bright and the color is very white. Look at the wall thickness of the profile. OK. The main wall thickness of the profile can reach more than two millimeters, and the toughness of the profile is also important.

You can use a vise to clamp the profile wall and break it back and forth. A good profile will not fall off easily. Strictly speaking, according to the national Industry regulations stipulate that processing of plastic steel windows is not allowed in environments below 10 degrees Celsius.

3. Look at the anti-counterfeiting inkjet code. There will be anti-counterfeiting inkjet code on the real profile. Generally, you can tell the authenticity without making an inquiry call. There will be 4 to 4 on a 6-meter-long profile. Among the 6 inkjet groups, first check whether the handwriting of the inkjet group is clear and complete. The inkjet groups for real profiles are unique, while the inkjet groups for fake profiles are all the same. Make an inquiry call to check the inkjet code.
