Ly profiles tell you how to distinguish the quality of profiles

Plastic steel windows are a common type of window and are also the largest in the market; Plastic steel windows have many advantages, such as sound insulation, thermal insulation, good airtightness, long service life, and high cost-effectiveness; But plastic steel windows have a major drawback: when distinguishing the quality of profiles, they require some small skills that non plastic steel professionals cannot access. Let’s take a look at some tips for distinguishing plastic steel windows.

Tips for distinguishing the quality of plastic steel windows: Step on them with your feet
Plastic steel windows are composed of plastic steel profiles, and the quality of plastic steel profiles is directly related to the quality of plastic steel windows; So when purchasing, you can take a section of plastic steel profile and step on it with your foot to test if it is qualified.
If you step on it with one foot, the plastic steel profile will directly break or shatter, and this type of profile either has less PVC main material or is made of plastic.
If you step down and the video below shows that the plastic steel is only deformed, broken, or intact, it indicates that the quality of this type of plastic steel is qualified, and both the raw materials and dimensions comply with national standards.
Technique 2 for Distinguishing the Quality of Plastic Steel Windows: Observing the Toughness of Plastic Steel
Plastic steel not only needs to have hardness, but also toughness, because hardness alone has low impact resistance, and hard materials can easily crack upon impact; High hardness and good toughness make windows made of this type of profile durable.
Use common pliers to grip the inner ribs of the profile. If it is easy to tear, it indicates poor toughness. If it requires a lot of force to tear, as shown in the video below, it indicates that the product is qualified.
Kind reminder: When purchasing plastic steel products, it is necessary to purchase them through legitimate channels. Do not buy products from small workshops at low prices, as such products cannot be guaranteed.
