Third - and fourth-tier cities will become doors and Windows enterprise layout direction
After the two sessions, the property market regulation has become a topic of concern. With the introduction of purchase restriction or upgrade policies in various provinces and cities, real estate sales may decline. As a downstream industry of real estate, the property market regulation policy will also have a certain impact on doors and Windows and other home furnishing industries, but the purchase restriction is not completely equivalent to restricting the development of the door and window market. In such a realistic background, three or four tier cities or doors and Windows enterprises will become the direction of the layout.

In such a realistic background, three or four tier cities or doors and Windows enterprises will become the direction of the layout. Many provinces and cities in China introduced new policies to limit and upgrade real estate purchases First-tier cities: on March 17, Beijing introduced new policies, requirements "household name in this city has a set of housing, and no housing but in this city have the record or housing accumulation fund loans of the commercial housing loans, the purchase of the ordinary from the housing deposit not less than 60%, the purchase of ordinary from the housing deposit not less than 80%". On the night of the 17th, Guangzhou also introduced new control policies. The threshold for non-resident residents to pay social security or personal income tax will be extended from three consecutive years to five years. Adults who are single or divorced can only buy one set, pointing to a loophole in "fake divorces". 2. First-tier cities around: with Beijing as the center, since March, there have been four cities such as Zhuozhou in Hebei, Laishui County in Baoding, Chongli District in Zhangjiakou, and Shijiazhuang, etc., which have successively introduced purchase restriction policies. Jiashan County in Zhejiang Province, which surrounds Shanghai, restricted the purchase of new and second-hand houses, explicitly suspending the sale of new commercial houses to non-registered residents who own one or more houses in Jiashan County. 3.

Third-tier and fourth-tier cities: Seeking progress while maintaining stability is the general keynote of current work. The reporter sorted out the relevant regulation policies and found that in the face of the demand spillover brought by the purchase restrictions, some third-tier and fourth-tier cities reflected the characteristics of "stability" between the treatment of "live" and "fire". For example, Shijiazhuang and Ganzhou did not implement the whole area purchase restriction in the regulation, but chose to push forward steadily in the central urban areas. There are certain limits on the number of years of paying social security or individual income tax for non-registered residents of the city, and the requirements on the duration of payment are not high. Property market control doors and Windows enterprises can focus on third - and fourth-tier cities For the doors and Windows industry, downstream for the domestic purchase of commercial housing and stock housing renovation of urban residents, as well as the launch of refined decoration of commercial housing real estate enterprises will still form a certain consumer market. "Purchase restrictions in some third-tier and fourth-tier cities indicate that they have entered a dual-track parallel mode of 'destocking' and 'housing price control', but destocking is still the core task of third-tier and fourth-tier cities, and purchase restrictions are mainly aimed at local areas." Visible, doors and Windows enterprises want to develop, sink the channel to three or four tier cities, it will be a wise choice. In fact, there is a higher correlation between the delivery time
Common problems in automatic induction door operation

Quality is not easy to guarantee, professional hospital special door production enterprises have strict specifications for each step of the production process to import equipment fine processing, to ensure that the quality of their products meet the requirements of the hospital. Service quality is different: meticulous, thoughtful, comprehensive service is an important condition to ensure the quality of the hospital special door. Ordinary decoration team because there is no special hospital door production and installation of professional training, at the same time on the production process, the use of materials and so on do not understand, the production of hospital door products without quality assurance, and once the problem is difficult to maintain, and no after-sales service. The special door service of SIG hospital not only includes pre-sale door-to-door guidance measurement design, sales of door-to-door installation guidance, but also includes after-sales service, such as the establishment of user files, timely return visit, timely treatment of problems and so on. Know the difference between medical doors and non-medical doors. So what are the requirements of the medical door? Special requirements for functions: 1. Standby power supply connection interface must be available. 2, there must be a delay closing the door function and two induction function. 3, must have the function interface to start the air shower equipment. 4. Non-contact proximity sensors must be set, such as non-touch manual sensors or foot sensors. 5. Enhance the anti-clip function to improve safety, and the door body must be set up with kill resistance bounce back function. Door sealing requirements: 1. The voltage range applicable to the electric control part should be wide. 2. The electric control part must comply with the relevant national electromagnetic compatibility standards to prevent interference to medical equipment. 3, the motor reducer should be special, minimize the noise to meet the requirements of clean room noise. 4, the door body, the outer surface of stainless steel plate, electrolytic steel plate, color steel plate, etc., stainless steel plate is the best, but the cost is higher. The middle sandwich is made of foaming process or honeycomb structure for the door body with radiation protection requirements. The middle sandwich should be sandwiched with lead plate of certain thickness. In addition, metope seam should have seal Mosaic.
