Whether it is doors and windows or hinge hinges and other hardware accessories, the products on the market have real and fake products, and with the increasingly fierce competition in the hardware industry, there are more and more fake and inferior hinge products. So, in this case, how can we distinguish the pros and cons of hinges?
First, look at the surface coating
Whether it is an iron hinge, a copper hinge or a stainless steel hinge, the hinges nowadays are basically coated with a layer of something on the surface, which may be zinc or other metal materials. The surface coating of inferior hinges is rough, not very smooth to the touch, and contains a lot of impurities; while the coating of high-quality hinges must be uniform and the length is relatively consistent.
Second, look at the quality of the material
At present, the stainless steel hinges with better quality on the market are mostly 304 stainless steel, with a thickness of about 3mm, and the color is relatively uniform, which looks heavy and thick. Inferior stainless steel hinges have uneven color, weight does not meet the standard, and edges and corners may have cutting edges.
Third, look at the effect of use
In addition to looking at the material and appearance, the pros and cons of hinges can also be distinguished by daily use effects. In order to reduce the cost of the inferior hinge hinge, the raw materials used are relatively poor. After a period of use, it is easy to rust, even make a "creaking" noise, and it is easy to be damaged. High-quality hinges are not only flexible and smooth, but also durable.
