The secret of buying a lock
Look at the material
Lock materials on the market are basically divided into stainless steel, copper, zinc alloy, steel and aluminum. Stainless steel has good strength, strong corrosion resistance and unchanged color, and is the best lock-making material. Copper is universal, superior in mechanical properties and expensive; High-quality zinc alloy is strong, wear-resistant, corrosion-resistant and easy to form, and is generally used to manufacture mid-range locks.
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 plays a role in corrosion prevention and rust prevention, and at the same time makes the product more beautiful and durable, which can directly measure the quality of the product. Locks with good quality are generally electroplated, with moderate and uniform coating, bright color and no signs of bubbles, rust and oxidation.
View functional design and key components
There are many kinds of locks, and the choice of locks depends on where they are used. Big brands with high quality requirements have very detailed product classification according to different functional requirements, such as access locks, bathroom locks, storage locks, large door locks and so on.
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 used some foreign standards for reference, and revised the GB originally implemented into the QB with higher requirements now. In order to save costs, small manufacturers do not produce according to standards, while big brands always produce according to standards.
Buying skills
To choose big brands with high reputation, good quality and a long history, small manufacturers often sell directly through some agents or shops, without the strength and stable system network to do after-sales service.
