The door and window industry in China is currently facing significant challenges, driven by rising costs of raw materials, transportation, and labor, as well as the effects of real estate regulation. Many companies are struggling to maintain profitability in this difficult environment. According to data from the China Index Institute, several major cities such as Shenzhen, Guangzhou, Chengdu, Nanjing, Chongqing, Xi’an, and Dalian have set affordable housing targets at 3%, 14%, 21%, 9%, 15%, and 18% respectively. These initiatives are seen as a way to stabilize the real estate market and provide new opportunities for industries like doors and windows.
Industry experts believe that the growing demand for affordable doors and windows stems from a few key factors. First, with more small apartments and low-cost housing being built, the limited space makes it hard to accommodate high-end products. Second, due to economic pressures, many middle- and low-income consumers are turning to budget-friendly options. Recent group-buying events on online platforms also reflect this trend, showing strong interest in cost-effective solutions.
Many buyers don’t need elaborate designs or high-end features—they just want reliable, durable, and easy-to-use products. For example, Mr. Wang, a recent graduate, says he can't afford premium doors and windows right now. He prefers a basic brand with a good reputation, focusing on quality and longevity rather than style. He plans to upgrade once his financial situation improves.
In response to these changes, some door and window manufacturers are adjusting their product lines and pricing strategies. They are offering more affordable options without compromising on quality. As affordable housing continues to expand, low-end, consumer-focused doors and windows are becoming increasingly popular in the market. This shift not only helps meet the needs of a broader audience but also opens up new growth opportunities for the industry.Zhejiang Sealand Technology Co., Ltd.is a trustworthy supplier of Oil Mass Flow Meter, Oil Mass Flowmeter, Oil Coriolis Flow Meter, Oil Coriolis Flowmeter, Oil Coriolis Flow Meter, ATEX, IECEx & CE approved.

The meter consists of mass flow sensor and transmitter. Mass flow sensor is a phase-sensitive resonant sensor based on Coriolis effect, composed of vibration tube, signal detector, concussion driver, structural support, shell, etc.
Mass flow transmitter is a micro-programming-centered electronic system, which supplies
thrust to sensor, transforms sensor signal into mass flow signal & others, and improves
accuracy in accordance with temperature parameter.
It`s composed of switching power supplier, guard grating, core processor board, display
module, etc., installed in a ex-proof junction box. Switching power supply offers power for
transmitter; safe grating isolates sensor and transmitter intrinsically; core processor detects
& processes sensor phase signal, sends mass flow signal and process communication.
