How to determine the quality of plastic steel doors and windows?

The hardware of high-end doors and windows are all made of metal, and their inherent strength, appearance, and usability directly affect the performance of doors and windows. Nowadays, many medium and low-grade plastic steel products on the market use plastic hardware, so their service life has great hidden dangers.

When purchasing plastic steel doors and windows, we need to pay attention to whether the welding corners are neat, whether the hardware is complete, and whether the appearance of the doors and windows is smooth and undamaged.
