How To Choose Locks?

1. 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 is the best lock-making material because of its good strength, strong corrosion resistance and unchanged color; copper is more versatile, has superior mechanical properties, and is relatively expensive; high-quality zinc alloy is strong and wear-resistant, with very strong anti-corrosion ability, easy to use Forming, generally used to make mid-range locks.

2. Look at the surface treatment

There are three general surface treatments: electroplating, spraying and coloring. Through these surface treatments, a protective film can be formed on the product, which can play the role of anti-corrosion and rust prevention, and at the same time make the product more beautiful and durable, and can directly measure the quality of the product. Good quality locks are generally electroplated, with a moderate, very uniform coating, bright colors, and no signs of air bubbles, rust and oxidation.

3. Look at the functional design and key components

There are many types of locks, and the type of lock you choose depends on where it is used. Large brands with high quality requirements have very detailed product classifications for different functional requirements, such as access locks, bathroom locks, storage room locks, door locks, etc.

4. Look at the 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 revised the originally implemented GB into the current QB with higher requirements by referring to some foreign standards. Small manufacturers do not follow the standards in order to save costs, while big brands will implement the standards when producing products.

5. Tips for buying

To choose a big brand with high reputation, good quality and a long history, small manufacturers often sell directly through some agents or shops, and do not have a strong and stable system network for after-sales service.

5. 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 thickened design. The high-quality zinc alloy locks used for door locks are beautiful, durable and economical.
