1. Purchase of high quality door handle
(1) pay attention to materials. For stainless steel door handle, one touch and two knock methods can be used to judge whether it is good or bad. Hold door handle, if the temperature is as fast as the hand temperature, it means that the pipe is relatively thin, otherwise, it means that the pipe is relatively thick. Or knock on the door and handle. If the sound is relatively clear, it proves that the pipe used is relatively thin. If the sound is relatively dull, it means that the pipe used is relatively thick.
(2) look at the surface technology. The surface technology of door handle can reflect the quality of door handle to some extent. The manufacturing cost of many door handle surface processes is higher than that of raw materials. Observing the surface process of door handle, we can see from the following aspects: if it is polished stainless steel door handle door handle, its surface should be smooth and translucent, without sand holes or silking, if the surface is foggy White, the grade is relatively low. If it is electroplated door handle, we need to see whether the color of the surface is pure and whether there are any spots.
(3) other aspects. The high-quality door handle packaging is also very formal, and there are multi-layer protective layers, while the low-grade one is relatively simple. In addition, when purchasing, we can check whether there is a trademark or a certificate.

(2) look at the hinge material. The Hinge of high-quality materials is usually made of brass or stainless steel. The color of the hinge of brass is as yellow as possible, and the more yellow it is, the higher the copper content is.

(2) weight. Generally speaking, the weight of a good quality contest is relatively heavy, so we can take two hinges to pick up the weight and buy the one with relatively heavy weight.
(3) look at the reset performance of the spring. The Hinge of good quality can be quickly reset when it is opened at 90 degrees.
