1. Materials
The main materials for doors and windows include aluminum profiles, glass, and hardware. When purchasing doors and windows, owners will pay attention to the thickness of aluminum profiles and glass, and directly ignore the requirements for hardware. This is not comprehensive. The country has strict regulations on the color of aluminum windows. There are certain requirements. For example, the thickness, strength, and oxide film of the aluminum profiles used in high-quality color aluminum windows can usually meet national standards. For example, relevant national regulations require that the wall thickness of aluminum profiles for color aluminum windows cannot be less than 1.2 mm. Above, the thickness of the oxide film must reach 10 microns, which is better than aluminum accessories in terms of hardware accessories. The pulleys should be made of POM products. Only in this way can the strength and wear resistance of doors and windows be effectively improved.

The wall thickness of the aluminum profiles used is 0.6 to 0.8 mm. Neither the tensile strength nor the yield strength meets the national standards, so these types of doors and windows are very unsafe.
4. Reputation
When choosing doors and windows, you must go for regular products and choose ones with a good business reputation and service quality. This is very important. For example, some brand doors and windows will go through the strict requirements of the inspection department before they can be sold before they leave the factory.
