There are a large number of door handle on the market, with varying quality. Good door handles have a long service life, while inferior door handles are prone to rust and other conditions after being used for a long time. So how should we choose door handles?
Manufacturing process
The quality of the door handle can be simply judged by its manufacturing process. When selecting, pay attention to checking for welding defects, such as open welds, missing welds, and other phenomena. Whether the opening is flexible, and whether all joints are dense. Generally, it should be painted and sprayed with plastic. The surface of the paint layer should be free of bubbles and have a uniform color. Most doors also have rubber sealing strips embedded in the door frame, which will not emit a harsh metal collision sound when closing the door.
2.Listening to sounds
Distinguish from sounds. Gently tap the handle tube with a hard tool, and the sound of the handle of the thick tube is relatively clear and crisp, while the thin tube is relatively dull.
