First, the material is very important
When choosing a door lock, it's essential to consider the material and its impact on both security and health. Comparing the advantages and disadvantages of different types of materials can help you make an informed decision. Opting for green and environmentally friendly products ensures the well-being of your family.
1. Aluminum - easy to process and shape; low development cost; soft texture, prone to deformation; low strength, poor impact resistance; monotonous color, susceptible to oxidation, short lifespan; simple design, low perceived value, and poor fire resistance.
2. Zinc Alloy - easy to cast, low development cost; available in various styles and colors; however, it has low strength, poor impact resistance, and weak rust resistance. Internal oxidation and spots may occur over time. It is brittle and can break easily, making it vulnerable to drilling, smashing, and cutting. Low material value and poor performance in cold temperatures.
3. Stainless Steel - highly corrosion-resistant, strong, and durable; offers excellent protection against drilling, smashing, and cutting. It has a uniform texture, high density, no pores or sand holes, and a bright, consistent color. While it is eco-friendly and has a premium look, the production process is complex and costly.
Second, preparing before purchasing a door lock
Before buying a door lock, it's important to measure the thickness of the door and the width of the door frame. This helps the salesperson configure the correct lock cylinder length and lock body width.
2. Determine whether the door opens on one side, both sides, or left/right. Understanding this allows the salesperson to select the appropriate door lock configuration. (Note: If the hinges are on the left side, the door opens to the left.)
3. Consider the color of the door and the overall home decor style.
4. Door hardware should complement the door lock’s design, creating a cohesive and aesthetically pleasing look that enhances the overall interior design.
Third, identifying stainless steel locks from zinc alloy ones
In recent years, health and environmental concerns have become increasingly important in home culture. As a result, copper locks with antibacterial properties and elegant designs are gaining popularity globally. However, the market is flooded with counterfeit products, making it difficult for consumers to distinguish between genuine and fake options.
In the market, zinc alloy and stainless steel locks often have similar surface finishes, which can lead to confusion. Salespeople might mislead customers by claiming a zinc alloy lock is stainless steel, especially when they don’t mention the material type. To avoid being deceived, it’s crucial to be vigilant. Here are some methods to help identify the difference:
Method 1: Weigh the locks. A stainless steel lock will feel heavier than a zinc alloy one of the same size.
Method 2: Use a sharp object to scratch the back of the panel. If it's hard and doesn't scratch easily, and the color remains consistent, it's likely stainless steel. If it scratches easily and reveals a silver-white color underneath, it's probably zinc alloy.
Method 3: Check the internal structure. Stainless steel panels typically don’t have positioning support holes in the center, while zinc alloy panels often do, with 4–8 holes distributed around the edges and center.
Method 4: Observe the surface. Stainless steel has a more natural, delicate finish and appears warmer under light, whereas zinc alloy tends to look colder and less refined.
Method 5: Look for reputable brands and compare prices across different stores.
Fourth, important considerations when selecting and using a door lock
1. Choose a door lock from a reputable brand that guarantees quality and reliability.
2. Ensure the lock is compatible with the direction your door opens.
3. Pay attention to the door frame width—ball locks and handle locks are not suitable for doors narrower than 90 cm.
4. During installation, only fold the end with the safety mechanism; never install it with the key in place.
5. Avoid putting oil inside the lock. If the key is stuck, try inserting a piece of pencil core into the keyhole to lubricate it.
6. If the house safety feature accidentally rotates to 90 degrees, it becomes a permanent lock. To fix this, turn it counterclockwise by 90 degrees.
7. Do not use a damp cloth to clean the lock or handle. Always push the lock tongue into the lock body before closing the door to extend its lifespan.
