With the continuous deepening of China's opening to the outside world, high-end construction has developed rapidly and the prospects of the premium lock market are optimistic. China's lock industry investment in high-tech locks is increasing year by year, and the market demand for high-grade locks has also increased year by year. In security engineering, the lock product of the access control system is an important device that relates to the security of the entire system. Therefore, the quality of the lock product is also related to the quality and acceptance of the entire security project.

Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.
Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.

Smart door locks are divided into IC card locks (card type), magnetic card door locks (card type), proximity card door locks and TM card door locks. Currently the most used card door locks and IC card locks, first according to their own hotel Management needs analysis, system cost selection suitable for the installation of that type of door locks. Because smart locks have different mechanical door locks, smart locks involve mechanical, electronic, and computer systems. It is recommended that mature brands with better reputation be used. At present, there are many smart lock brands in China, but there is an estimated total production capacity of less than 10%. It is better to understand the The development, production, and after-sales status of the manufacturers are whether they are standardizing enterprises and whether they have established a quality management system. There are many users who lack experience in purchasing or only require cheaper (those brands may be cheaper locks, but other accessories or card issuing machines are expensive, and when the free delivery, the maintenance price is several thousand dollars), purchased the product After some time may not find the manufacturer, or there are quality problems to find irresponsible manufacturers believe that improper use of the user does not give maintenance or accessories sky-high phenomenon. The above phenomena are even difficult for the court to decide.
Smart locks
It is precisely because smart locks are increasingly favored by consumers and hotels, but as consumers should even know some of the common sense in the purchase of smart locks, so I will teach you how to buy smart lock today! The door lock must be sensitive when inserting a card or sensing a key card. If you want to insert the card repeatedly or the key card is open, you should run normally. There should be no "no response" or "error" or "motor rotation" phenomenon. To investigate the information on the brand's door locks, the clock volume is not easy to confuse. As long as the performance of the smart door lock is checked, those so-called additional functions may not be effective. The door lock of the self-correction function circuit should be selected. If you choose an immature product, you may not be able to use or maintain it. Keyu intelligent door lock circuit microcomputer chip control, the circuit comes with information error correction function, so that the circuit processing information is more stable, the sensor door lock adopts dual clock correction error rate is very low, the sensor door lock adopts wireless data collector for door lock maintenance, It is very convenient to collect open record data. Select the sensor card door lock first check the sensitivity of the sensor and then understand the static power consumption of the sensor door lock, because the general sensor door locks are powered by dry batteries. It is very important to understand the static power consumption of the sensor door locks. Some of the current brands of sensor door locks The battery can be used continuously for more than one year. Some brands replace the battery in less than a month. Frequent battery replacement will seriously affect the use. When selecting the magnetic card door lock, it should be understood whether the door lock reader is a self-developed card reader's own encryption algorithm, or adopts a common magnetic card reader card on the market. If a card is written using a universal card reader, others can use a universal card reader to copy the card without achieving confidentiality. Keyu newly introduced IC card plus magnetic card door lock, guest card with magnetic card, administrator and maintenance information IC card, magnetic card reader's card reader module own encryption algorithm. The use of smart door locks to select the door lock panel material and the surface plating is uniform, claiming whether the copper panel is using copper or gold plated imitation gold, whether the use of stainless steel 304 stainless steel or 2-3 times lower price of stainless iron, Users can also choose PVD surface treatment. If the plating surface is to be used, it depends on whether the surface of the door lock has protective lacquer. Keyu has always insisted that the products are real materials, such as the nominal pure copper panel, the handle must be pure copper, such as the nominal 304 stainless steel material must be 304 stainless steel. Pure copper forged made of imported high quality brass rods. The thickness and weight of the panel can be guaranteed. The plating layer completely meets the salt spray test standard.
