In the 1950’s, Young Poong focused on analyzing and exploiting minerals and founded Chilseong Mining and Daeyu Titan Industry. Young Poong, after acquiring Yeonhwa Mine in Bonghwa-gun, Gyoengbuk Province, developed it as the domestically largest base to produce lead and zinc. Thereafter, in 1970, Sukpo smelter was established, and zinc smelting technologies were adopted, laying the foundation for the domestic non-ferrous metal industry. Sukpo smelter increased its annual zinc production to 31,000 tons by 1977, securing global competitiveness.

In 1974, the Onsan smelter of Korea Zinc was established in response to the Korean government’s policy to develop the heavy chemical industry. The Onsan smelter grew to have the world’s largest zinc smelting capacity, and Young Poong and Korea Zinc secured an unchallenged position in the global market through partnership.

Young Poong entered into e-business in the 1900’s and began manufacturing flexible printed circuit (FPC) boards. Its technological prowess was recognized with an achievement to supply printed circuit boards (PCB) to the National Aeronautics and Space Agency(NASA) for its Mars rovers. In 2025, Young Poong acquired Korea Circuit which is a company specializing in PCBs and rose to become the second largest company in terms of market share of the domestic PCB market. Young Poong expanded business areas by supplying products to global IT companies such as Samsung Electronics and Apple.

In addition, Young Poong acquired Signetics, a company specializing in semiconductor packaging and entered into the semiconductor back-end process market. Signetics showed strengths in the field of non-memory semiconductor, secured global customers and continued its growing trend.

In October 2009, Young Poong Sukpo smelter was awarded an appreciation plaque in the "2009 Power Demand Resource Market" in recognition of its contribution to the stability in power demand and supply during the summer season with the maximum electric power generation. Young Poong Sukpo smelter reduced 182,000kW load equivalent to 53% of the load reduction quantity of 364,000kW in the entire power demand resource market.

Young Poong maintains a global standing in the non-ferrous metal industry and pursues sustainable growth. Sukpo smelter and Onsan smelter boast the world’s largest capacity to manufacture zinc. Young Poong Group manufactures about 1.27 million tons of zinc ingots per year, accounting for about 10% in the share of the world market. As such, Young Poong has unchallenged competitiveness in the global non-ferrous metal market. To grow together with local communities commensurate with its achievement, Young Poong carried out various social contribution activities such as construction of apartments for employees, educational support, and expansion of welfare facilities.

Sales growth also continues in the fields of electronic components and PCB based on major customers such as Samsung Electronics and Apple. Young Poong now focuses on technological development as well as the expansion of the smartphone and tablet PC market.

Young Poong Group pursues a sustainable future through technology innovation and environment-friendly management. In the non-ferrous metal industry, environmental impact is minimized through resource recycling and high-efficiency manufacturing processes. In the electronic parts industry, the development of high value-added products and the expansion of the global market are set as goals. Furthermore, a new chapter for secondary battery recycling has been opened as a new business.

In addition, Young Poong has evolved into a platform-based enterprise dealing with comprehensive parts by strengthening cooperation between subsidiaries. Young Poong continues its sustainable growth while seeking new business opportunities.
