The company first makes wire rod by heating, rolling, and pressing 12-meter-long, 15-centimeter-square steel billets weighing 2,000 kilograms into a jelly-roll shape. It next spheroidizes the wire rod to make it softer and more ductile, then draws, phosphatizes, and rustproofs it to create the wire it uses to produce fasteners.
所謂「盤元」，是由一根根 15 公分見方、長達 12 公尺、重達 2,000 公斤的柱狀鋼胚經由高溫處理、滾動壓製而成一捲捲如瑞士捲般的盤元；經過「球化」──改變內部結構、降低硬度，再加上拉細、酸洗、防鏽製程，即成為製作螺絲的「線材」。
