"System products" are certainly more expensive in terms of price. As I mentioned before, system doors and windows need to be tested thousands of times before they are released to the market, and they are finally certified. This means that system companies have to invest more in R&D and testing. It is precisely because of this that system doors and windows can provide more stability and reliability to end users.

At the same time, all the testing and certification work was completed by the system company in the early stage, which also saved the related energy, time and expenses for investors and developers, and ensured safety, which ultimately reduced the cost to a certain extent. In Germany, there is a saying: If you want to buy cheap, then prepare to buy it twice.

Developers and investors always try to find a balance between quality and cost. Today, more and more Chinese developers begin to pay attention to quality. They not only pay attention to project construction itself, but also pay more attention to long-term interests and reputation among end users. Schüco was established in 1951. In Germany, we have cooperated with some metal processing companies, architects and developers for more than 60 years and have inherited from two to three generations. Similarly, in China, I believe that we will achieve such cooperation in the next 50 years.
