Hinges, also known as hinges, are mechanical devices used to connect two solids and allow relative rotation between them. The hinge can be composed of movable components or foldable materials.
Below we will tell you how to judge the quality of hinges!
Firstly, look at the surface coating
Whether it's iron hinges, copper hinges, or stainless steel hinges, nowadays hinges are basically coated with a layer of zinc or other metal materials on the surface. The surface coating of low-quality hinges is rough, not very smooth to the touch, and has a high content of impurities; And high-quality hinge plating is definitely uniform, and the length is also relatively consistent.
Secondly, look at the quality of the material
Nowadays, high-quality stainless steel hinges on the market mostly use 304 stainless steel, with a thickness of about 3mm and relatively uniform colors. They look very heavy and thick. Poor quality stainless steel hinges have uneven colors, weight that does not meet standards, and may have edge edges.
Thirdly, see the effectiveness of use
In addition to looking at the material and appearance, the quality of the hinge can also be distinguished through daily use effects. Due to the poor quality of hinge materials used to reduce costs, they are prone to rusting and even making "creaking" noises after a period of use, and are prone to damage. And high-quality hinges are not only flexible and smooth to use, but also durable.
