Experts teach you how to choose a lock

Locks are the most important safety components for ordinary families. As the number of burglary or unlocking incidents increases, people's emphasis on locks has increased. But in the face of a wide variety of locks, many buyers are confused because these locks are either very expensive or have poor quality. So, how can we pick a safe and durable lock? The expert advises you to look at the following key points:

See materials

The lock material on the market is 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 material for making locks; copper is universal, its mechanical properties are superior, and its price is expensive; high-quality zinc alloy is strong and wear-resistant, and its corrosion resistance is very strong. Molding, 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, which can prevent corrosion and prevent rust. At the same time, the product can be more beautiful and durable, and can directly measure the quality of the product. Good quality locks are generally plated. The coating is moderate, very uniform, and bright in color with no signs of bubbles, rust, or oxidation.

See functional design and key components

There are many types of locks, and what kind of locks to use 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 room locks, and door locks.

See standard implementation

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 drawn reference to some foreign standards to revise the original implementation of GB to the current more demanding QB. Small manufacturers do not perform according to standards in order to save costs, and big brands will implement standards when producing products.

Buy Tips:

To select large brands with high reputation, good quality and long history, small manufacturers often sell directly through some agents or shops, and do not have the strength and stability of the system network to do after-sales service.
