Two. How to select locks
1、 Inspect the materials
The locking materials available on the market are primarily categorized as stainless steel, copper, zinc alloy, iron, and aluminum. Stainless steel offers excellent strength, corrosion resistance, and consistent color, making it the ideal material for lock manufacturing. Copper is a common choice, offering superior mechanical properties and a higher price point. High-quality zinc alloys are robust, wear-resistant, and have excellent corrosion resistance, making them easy to form and typically used for manufacturing mid-range locks.
2、Inspect surface preparation
Common surface treatments include electroplating, spraying, and coloring. These treatments create a protective layer on the product, providing corrosion and rust protection, while also enhancing the product's appearance and durability, allowing for a direct assessment of product quality. High-quality locks typically undergo electroplating, with coatings that are appropriately uniform, vibrant in color, and free from bubbles, rust, and oxidation.
3、Review the functional design and key components.
There are many types of locks available, and the choice depends on the intended use. High-quality brands offer comprehensive product categories tailored to specific functional requirements, such as door locks for corridors, bathroom locks, storage room locks, and main door locks.
4、Check the origin
Foreign countries have very strict standards for hardware locks, so the quality of imported products is generally superior.
