How to distinguish the hinge quality?

1. Material

Most hinges on the market are made of stainless steel and cold-rolled steel. Stainless steel has better rust resistance, but it is also more expensive. Cold-rolled steel is more common. Good quality hinges are made of thick materials, strong and durable, and have better load-bearing capacity. Inferior hinges are generally made of thin iron sheets, with almost no resilience. They will lose the elasticity after a while of use, causing the cabinet door to not close tightly or even crack.

2. Surface

Premium hinge surface is smooth and has the thick coating. Under the nickel plated surface, there is also a copper plated base, so it is not easy to rust. Standard hinge is only coated with a layer of nickel on the surface, rust resistance is not as good as the one with copper bottom, but there is basically no difference between the two surfaces, so it is difficult to distinguish them just by looking at the surface.

3. Weight

Generally speaking, for the same type hinge, the heavier the weight, the better the quality. For example, for two-way slide on hinge, there are different weights from 46-65g, a 65g hinge is normally better than a 46g hinge.

4. Life cycling test and salt spray test

Hinge testing is generally divided into the following levels:

5. Screws

The screws of good hinges are not prone to stripping, while the screws of poor quality hinges are easy to strip. If it needs to drill the screw again, poor quality screws may not be able to be used twice.

7. Functional performance

High-quality hinges are designed to be silent, and the force used to open the door is relatively gentle. When the door is closed to 15 degrees, it will automatically rebound, and the rebound force is very uniform. Low-quality hinges are generally made of cheap metals such as thin iron sheets, and the door will stretch awkwardly and even make a harsh sound.

In brief, judging the quality of a hinge requires evaluating from multiple details, and the price is also one of the factors. There is an old Chinese saying that you get what you pay for. Good things are definitely not cheap, and cheap things are generally not so good.
