How to choose interior door handles
The door handle we are talking about today is also known as the handle lock. It's the kind that has a handle and a lock. With the spherical lock slowly withdrawing from the market, the handle lock has become one of the main types of indoors in today's society. Let's see how to choose.
1. Select materials
Today's mainstream materials include space aluminum, stainless steel, copper die-casting, and zinc alloy.
Space aluminum and stainless steel materials are ideal, but the price is slightly higher. After surface treatment, the luster is bright, the handle is soft, and it is not easy to fade and rust after being corroded.
Die-cast copper locks are thicker and more affordable.
The poor quality is generally because zinc alloy locks are easy to break when used, and their strength and anti-rust ability are very weak. Some Fingerprint Door locks will be plated with copper on the surface, so they feel similar to copper die-casting locks when purchasing. (Use a file knife to file the bottom plates of the two types of locks. The brass-colored one is a uranium die-cast handle lock, and the silvery-white one is a zinc alloy lock.) However, it is generally impossible to do the above attempts when purchasing. You can consider asking the merchants clearly, and you can't blindly seek cheapness. The handle is generally relatively thin, and the general pattern workmanship is relatively complicated. Generally, the patterns and styles are relatively complicated and the cheap ones are generally zinc alloy locks. It is not recommended to buy it.
2. Choose a business
Generally, the price of door handles is basically acceptable. It is recommended to choose door handles that are well-known, guaranteed in quality, and have after-sales services.
3. Check the product
Including inspection implementation standards, grades, production company name, address, production date, manual and product comparison. Whether the product is complete, including whether the lock head, door lock, lock tongue, handle, and other components are complete.
4. Check for rust, oxidation, and damage.

Needless to say, this is to try to open the lock with each key to see if there is any blockage or other unsmooth conditions. Special attention should be paid to the two-way lock, it is best to try both inside and outside.
5. Purchase environment
Many people may ignore this. Before buying a lock, consider the environment in which the lock will be used, such as humidity, the structure of the door, and the way the door is opened.
6. No opening rate
This problem is really embarrassing. Some brands of keys can open many locks of the same type. It is recommended that you try to choose a key with more complicated key teeth. This can effectively reduce the mutual open rate.
The above is the method of choosing door handles, I hope it will be useful to you. It is not recommended that you use relatively thin locks at home, it is better to have no locks. In addition, the key must be kept well, otherwise the better the lock, the worse the memory... It's embarrassing.
