What are some tips to share when choosing a padlock?

Padlocks are the oldest and largest family in the world of locks, and it can be said that other locks have evolved and derived from this category. The lock body of the padlock is equipped with a metal stem in the shape of a ring or a "letter" that can be buckled, which is called a "lock beam", allowing the padlock to be directly buckled with the lock body through the lock beam to form a closed lock.

Tips for purchasing padlocks:

1.Look at surface treatment

There are generally three types of surface treatments: electroplating, spraying, and coloring. Through these surface treatments, a protective film can be formed on the product, which has anti-corrosion and rust prevention effects. At the same time, it makes the product more beautiful and durable, and can directly measure the quality of the product. High quality locks generally use electroplating treatment with a moderate and very uniform coating, bright colors, and no signs of bubbles, rust, or oxidation.

2.Look at the materials

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 unchanged color, making it the best lock making material. Copper is more versatile, has superior mechanical properties, and is also more expensive than price. High quality zinc alloy is sturdy, wear-resistant, and has strong corrosion resistance, making it easy to form. It is generally used to manufacture mid-range locks.

3.Check the color and workmanship of the lock cylinder.

The high-quality lock core adopts electroplating treatment, with a smooth surface and bright color. The copper core with a dark yellow color is relatively sturdy and has good anti-theft performance. The lock core has a dull color, and the zinc alloy with gray white bubbles has average anti-theft performance.
