Locks are the most important safety components of ordinary families. Due to the increasing number of shackles or unlockings, the importance of locks has increased. But in the face of a variety of locks, many buyers are confused, because these locks are either expensive or unsatisfactory. So, how can we pick a safe, usable and durable lock? The expert prompts you to look at the following key points:
Look at the material
The lock materials on the market are basically divided into stainless steel, copper, zinc alloy, iron steel and aluminum. Stainless steel has good strength, strong corrosion resistance and constant color. It is the best lock material; copper is more versatile, mechanical properties are superior, and the price is also expensive; high-quality zinc alloy is strong and wear-resistant, anti-corrosion ability is very strong, easy Forming, generally used to make mid-range locks.
Look at the surface treatment
The general surface treatment includes electroplating, spraying and coloring. Through these surface treatments, a protective film can be formed on the product to prevent corrosion and rust, and at the same time, the product is more beautiful and durable, and the quality of the product can be directly measured. Good quality locks are generally electroplated, with a moderate coating, very uniform coating, bright colors, no signs of air bubbles, rust and oxidation.
See functional design and key components
There are many types of locks, and what kind of locks to choose depends on where they are used. Large brands with high quality requirements have very detailed product classifications for different functional requirements, such as channel locks, bathroom locks, storage locks, and door locks.
See standard execution
Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively superior. At present, the Ministry of Light Industry has used some foreign standards to revise the original GB to become a more demanding QB. Small manufacturers do not perform according to standards in order to save costs, and big brands implement standards when producing products.
Buy a small trick
It is necessary to select large brands with high reputation, good quality and long history. Small manufacturers are often sold directly through some agents or shops, and there is no strength and stable system network for after-sales service.
According to their own economic ability and practical use. Different locks are designed for different houses and doors. Villa apartment locks have higher requirements and higher prices, but ordinary houses do not need to use such expensive locks. Generally, the entrance door is made of stainless steel, copper or thicker. The high quality zinc alloy locks, while the high quality zinc alloy for the door locks are aesthetically pleasing and economical.
To lick the weight, feel better than the hand, listen to the sound. This is the same as picking the faucet. It is also known as stainless steel, pure copper or zinc alloy. Some small brands will cut corners and use hollow materials and inferior materials. These materials are very light and have a bad hand. The sound is very stuffy; the good lock is the opposite.
To see if there are instructions and installation instructions, the effort is in the details. Without these two things, it is easy to cause incorrect installation or not to use, and even the door is destroyed.
