前言 隨著東和鋼鐵苗栗廠的窄幅鋼板和扁鋼胚連續鑄造設備先後的投產, 東和鋼鐵由長條類鋼品跨足平板類鋼品, 成為台灣鋼鐵業中第一家可同時供應鋼板 熱軋 H 型鋼 鋼筋等建築結構用鋼的專業生產鋼廠 台灣位處地震頻繁地帶, 建築結構設計必須要對耐震功能作更嚴謹的考量, 而現行 JIS/CNS 規範中之熱軋 H 型鋼由於截面模數及強 弱軸特性之限制, 使得國內設計師使用箱型柱 (Box Column) 及高樑深 寬翼緣 大厚度組合 H 型鋼來搭配熱軋 H 型鋼之情形亦相當普遍, 東和鋼鐵為滿足設計者及使用者之需求, 以減少裁剪加工及降低鋼材耗損為目標, 積極投資扁鋼胚 小鋼胚複合連續鑄造設備, 跨足平板類鋼品, 投入窄幅鋼板之生產製造 東和鋼鐵公司本著專業的品質管理制度所生產之窄幅鋼板, 不僅能確保建築結構用鋼之安全性, 並將依客戶所要求之交期, 作計畫性之生產, 提供確實配合 如期之交貨規劃, 全面滿足客戶在使用上之需求 With the commissioning of the slab continuous caster and universal plate production at Miaoli Works, Tung Ho Steel has expanded from long product production to flat product production. Tung Ho has become the first dedicated structural steel maker in Taiwan with the capability of supplying hot rolled Hbeam, universal mill plate and rebar. As Taiwan is located in an earthquake zone, protection against earthquake has been the most critically considered element in structural design. Due to the fact the Hbeam's structural strength has one stronger axis and one weaker axis, Taiwan's structural designers have also considered using column boxes and jumbo welded beams (BH) in connection with Hbeams. Thus, in order to fulfill these diverse needs in steel structural design, and to minimize cutting losses in fabrication, Tung Ho aggressively invests in slab continuous casting machine and expands its steel plate production. Under Tung Ho's tight quality control system, Tung Ho's steel plate can fulfill the safety requirements in structural design. In addition, Tung Ho's flexible production pattern and production schedule allow timely deliver and complete satisfaction to the customers.
