How can fastener companies become "hidden champions"?

Have you heard of the "invisible champion"? Why is the "champion" still "invisible"? The so-called invisible champion refers to the invisible world champion enterprises in the basic fields of manufacturing basic components (components), basic materials, industrial software and industrial Internet. "Invisible" means that the main product parts (components), materials or software of an enterprise are "invisible" inside the terminal product, which is not easy to be discovered and attracts attention. "Champion", refers to the invisible world champion (or top three in the world). The Hidden Champion is a world-class "specialized little giant". This concept originated from Hermann Simon, a famous German economist and management scientist. He believed that a hidden champion should have three criteria: (1) the top three companies in the world or the first company on a certain continent; (2) Companies with a turnover of less than EUR 5 billion; (3) Companies that are not well known.

Anticorrosion measures for door and window hardware accessories

Modern building doors and windows can be roughly divided into plastic windows, composite windows, and aluminum alloy windows according to the types of profiles. Among them, aluminum alloy windows are the main building doors and windows in my country today, accounting for a considerable proportion in today's buildings. In fact, aluminum alloy windows have their advantages in terms of wind pressure resistance, water tightness, air tightness, and environmental protection. This is because compared with plastic windows of the same section, the moment of inertia of aluminum alloy windows is 3-4 times that of plastic windows; with the use of thermal insulation bridges in aluminum alloy profiles, the thermal insulation and thermal insulation properties of aluminum alloy windows are greatly improved. It is very suitable for the energy-saving requirements that are vigorously advocated today.
