What are the issues to pay attention to when choosing a door handle?

Due to the general lack of national standards for door handles, most consumers have little knowledge about the quality of door handles. It should be noted that most of the handles we see on the market now are low-end goods, because many people prefer to buy cheaper goods in order to fish in troubled waters

To sell to customers. Therefore, as consumers, we should be cautious when making purchases to avoid causing ourselves big trouble due to quality issues with the door handles.

1、 Pay attention to the materials

不銹鋼拉手廠家

For stainless steel door handles, there is a potential danger of being hit and dented. When purchasing, touch and tap the steel pipe. If the steel pipe quickly becomes the same temperature as the palm of the hand, it indicates that the steel pipe is thin. When we tap the steel pipe with our fingers, if it is thick, the sound will be very clear

Crisp, without a dull buzzing sound. Of course, it cannot be ruled out that some unscrupulous manufacturers may deceive consumers by filling cement inside. We need to keep our eyes open when making purchases. For door handles made of brass, zinc alloy, and other suitable profiles, we need to consider whether they can maintain deformation under strong conditions. Secondly, do not use functional accessories, as this will increase the risk of theft.

2、 Look at the surface craftsmanship

If the surface of the polished handle is as transparent and clean as a mirror, it belongs to a higher grade handle, if there is wire drawing. Try not to consider purchasing for phenomena such as pockmarks. If it is an electroplated handle surface, we also need to carefully check whether its color is pure and whether there are any black spots or other electroplated features

Defects. Then we need to examine the craftsmanship of the handle as a whole, not only considering whether the product has a regular appearance, but also achieving clear edges, smooth lines, and a harmonious appearance. If there are burrs, cracks, and other conditions on the surface, it cannot be purchased.
