Company Milestones

San Tai Mine was founded in 1973. At the time, Taiwan’s stone-processing technology was still underdeveloped. Serpentine extraction relied mostly on manual labor, diamond wire saws, and even blasting, while many mining areas were located along steep valleys, making operations difficult and risky.
Despite these limitations, the company began developing serpentine resources and basic processing, laying the groundwork for its early mining expertise.
 

In 1996, with guidance from Taiwan’s Mining Bureau, San Tai Mine became the first in Taiwan to introduce high-efficiency Italian diamond chain saws.
This shifted the extraction process from blasting to precise and stable mechanical cutting. The terraced rock formations created by chain-saw operations also gave the Yuli mining area its distinct and recognizable landscape.

San Tai Mine became one of Taiwan’s major developers of Verde Serpentine, supported by stable mineral reserves and production capacity.
The company promoted Taiwanese serpentine in both domestic and international markets, including architectural, material, and engineering applications. It also implemented resource-reuse initiatives by supplying stone offcuts to steel manufacturers as smelting flux.

Located in Hualien, the Gau Yang Yi Enterprise factory has become one of Taiwan’s key serpentine processing bases. The facility integrates extraction, cutting, polishing, quality control, and packaging into a streamlined, high-precision production process that supports numerous domestic and international construction and design projects.

In 2025, Gau Yang Yi Enterprise Co., Ltd. officially obtained the "Eco-Friendly Green Building Material Certification." This recognition symbolizes the company’s achievements in material processing, environmental management, and product sustainability.

Through this certification, the company not only reinforces its professional image in quality management but also demonstrates a long-term commitment to promoting green manufacturing and practicing circular utilization.
