Lock selection skills

Lock selection skills:

Look at the material: 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 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, and its corrosion resistance is very strong and easy. Forming, generally used to make mid-range locks.

Look at the surface treatment:

The general surface treatment includes electroplating, spraying and coloring. These surface treatments can form a protective film on the product, which acts as anti-corrosion and anti-rust, and makes the product more beautiful and durable. Good quality locks are generally electroplated, with a moderate coating, very uniform coating, bright colors, no signs of air bubbles, rust and oxidation.

掂 Weight is better than the sound of the hand:

To lick the weight, feel better than the hand, listen to the sound. The products that cut corners are made of hollow materials and inferior materials. Such materials are very light and have a bad hand feeling, and the sound is very stuffy; good locks are the opposite.
