Dalian Shangli Technology Co., Ltd. was established in 2005, by a group of professionals who love hot-dip galvanizing. In the past 18 years, Shangli has been deeply engaged in the galvanizing industry, and expects to be based in China and serve the world.

In 2003, the first set of high-velocity pulse fired galvanizing furnace was introduced from the United States; in 2005, the high-velocity pulse fired technology was deepened, and in the same year, it was quantitatively produced locally; in 2008, the overall planning and design of the whole plant's environmental protection galvanizing line began, and so far dozens of production lines have been put into operation smoothly; in 2012, the largest galvanizing furnace in China at that time was built 15.0x3.0x4.2; in 2014, the galvanizing line with an annual output of 90,000 tons was designed and built; and in 2016, the first circular galvanizing line on the plateau was designed and built; in 2018, we actively focus on overseas markets and designed integrated galvanizing furnaces to facilitate overseas customers' self-installation; in 2020, we developed and constructed fully automated galvanizing production lines, and customers can  monitoring remotely.
