We were Taiwan’s first qualified vendor to produce

The company’s ductile iron parts for tunnel linings are better suited for tunnels built at
special stratum as compared to traditional materials such as cement or steel parts.

Cast Iron Tunnel Linings v.s. Steel Tunnel Linings
• Outperform in erosion and oxidation resistance
• Outperform in electrode resistance
• Outperform in compression resistance

In 2009, the company shipped tunnel linings in ductile iron for the “CG590B” section of
Taipei MRT Songshan Line project and thus became Taiwan’s first qualified vendor to
produce tunnel lining parts in cast iron. Its product quality and safety is guaranteed.
