Rongtai Hardware was established in 1990. It's one of the first companies to manufacture window friction hinges in China, with its factory base located in Shantou, China. In the last 20 years, we extended our production to window hardware, door hardware, and furniture hardware.
In 2002, Rongtai Hardware set up the earliest hardware network company domestically: "Rongtai Science and Technology Network Company", and established sales offices in Shantou, Chongqing, Guangzhou, and other major cities.
In 2006, Rongtai Hardware Products Ltd was registered in Hong Kong, working closely with the Rongtai Hardware Guangzhou International Sales Department. Since then, Rongtai Hardware has maintained an independent export team and achieved global distribution.

We have built a solid reputation and strong market presence domestically, while the majority of our products are exported globally across Europe, America, the Middle East, Singapore, Malaysia, and beyond.
