At present, the locks on the market are complex and diverse, and the processing technology is also different. Although there are many styles of locks, they are still basically the same. The editor of Chang Yi Hardware has compiled some things to pay attention to when buying hardware locks. I hope it will be helpful to everyone in choosing locks!
1. The unlocking tool material
The lock materials on the market are basically divided into stainless steel, copper, and zinc alloy. Stainless steel has high strength, strong corrosion resistance, and does not change color. It is a good lock material. Copper is more versatile, has superior mechanical properties and higher prices. The locks are high-quality zinc alloys that are strong, wear-resistant, corrosion-resistant, and easy to form. They are mostly used for mid-range locks.
2. Observe the surface treatment of the lock
Surface treatment is roughly divided into three types: electroplating, spraying and coloring. The lock forms a dense protective film on the surface of the product through surface treatment, which plays a role of corrosion and rust prevention, making the lock more beautiful and durable. Dense protective film is also a measure of the quality of locks. Good quality locks are mostly electroplated. The coating is fine and smooth, uniform and moderate, bright in color, without bubbles, rust and signs of oxidation.
Three, pay attention to the lock implementation standards
Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. We can feel the quality of the lock by hand. Generally speaking, locks that feel heavy are of relatively high quality. The tip of the lock body should not be exposed. The tip of the lock body can easily hurt people. Pay special attention to the three positions of the lock handle end, the bolt and the four corners of the lock body. The lock with a good lock spring can open flexibly, with high sensitivity and long service life. There are also many styles of locks, so be sure to keep consistent with the style of interior doors.
The above are the things to pay attention to when buying hardware locks. When choosing locks, you can choose according to the above selection criteria, which can avoid the distress of choice. If you want to know more about hardware accessories, please contact our customer service.
