YIEH PHUI ENTERPRISE Business Summary

Yieh Phui Enterprise Ltd. (2023.TW) operates a diversified industrial business model primarily centered on the production, processing, and global distribution of high-end coated steel products. The company generates the majority of its revenue through two core segments: the Coated Steel business, which specializes in hot-dip galvanized and pre-painted steel coils for the construction and appliance sectors, and the Engineering business, focused on the design and installation of large-scale steel structures and crane equipment. As of early 2026, Yieh Phui maintains its position as the largest independent coated steel producer in Taiwan and Southeast Asia, leveraging a vertically integrated supply chain within the broader E United Group. It competes directly with major regional players such as Ta Chen Stainless Pipe, Tung Ho Steel Enterprise, and Chung Hung Steel, distinguishing itself through a high-density production capacity of 1.35 million tons and a growing strategic pivot toward green, low-carbon steel and solar photovoltaic applications. The company was founded in 1978 by Chairman I-Shou Lin, a prominent industrialist who also leads the E United Group and established the firm's foundational footprint in Kaohsiung. The current executive leadership is headed by President Jeff Chang (Chang Chen-Wu), who oversees global market expansion and the transition to sustainable manufacturing, supported by Vice President of Technology Wen-Chao Hwang, who serves as the technical lead with an extensive background in metallurgical and materials engineering. The corporate governance structure is bolstered by a seasoned board including Director Ping-Yong Liang and Senior Consultant Ching-Tsung Huang. Notable institutional backing is provided by major global investors, including The Vanguard Group, BlackRock (via iShares), and Dimensional Fund Advisors, reflecting the company's significant weight within emerging market equity portfolios.
