Maintenance and care of plastic steel doors and windows

1. Clean the dust on doors and windows regularly to keep them clean and bright, as well as glass and hardware.

2. If the doors and windows are contaminated with oil stains or other things that are difficult to clean, you can use cleaning agent to clean them. It is best not to use strong acid or strong alkali solutions to clean them. This will not only easily damage the surface finish of the profile, but also damage the protective film and oxide layer on the surface of the hardware, causing rust on the hardware.

3. Granular and other debris on the inside of the frame should be cleaned in time to prevent them from blocking the drainage channel and causing poor drainage and water leakage.

4. When opening doors and windows, the force should be moderate, and the speed of opening and closing should be kept uniform as much as possible.

5. Try to avoid hitting doors and windows with hard objects or scratching the surface of upvc profiles

6. When it is found that the doors and windows are not flexible to open or other abnormal conditions during use.
