What Xi'an Triangle Defense does
Xi'an Triangle Defense (西安三角防务股份有限公司) is a publicly listed Chinese aerospace and defense manufacturer specializing in large-scale precision forging equipment and the production of aerospace structural components. Founded in 2002 and headquartered in Xi'an, Shaanxi Province, the company operates from 501-1000 employees and trades on the Shenzhen Stock Exchange ChiNext board (symbol: szse:300775). It is controlled by Yan Jianya, Shaanxi's wealthiest individual with a personal fortune of 33 billion yuan, who also controls Giant Biogene and Sanrenxing through a shared portfolio of listed companies.
The company's core product portfolio centers on five major pieces of industrial forging equipment: the 400MN Large Aircraft Die Forging Hydraulic Press — designated as a national "12th Five-Year" major science and technology support project and leveraging Tsinghua University wire prestress winding and ultra-high pressure core technologies; the 300MN Isothermal Forging Hydraulic Press for high-precision forging of difficult-to-deform materials such as high-temperature alloys and titanium alloys; the 31.5MN Fast Forging Machine supporting multiple pressure modes; the EP-8000A 80MN Heavy Electric Screw Press for cross-industry precision forging; and a Precision CNC Ring Rolling Machine for shaped cross-section ring components. The 400MN press is positioned as key foundational equipment for the die forging of large and medium structural parts for large aircraft, serving as a strategic national asset in China's aerospace manufacturing infrastructure.
The business model operates on a B2B direct sales basis, supplying precision-forged components and forging equipment primarily to domestic Chinese aerospace and defense manufacturers. Distribution is conducted through direct manufacturer relationships within a single-country (domestic) channel, with pricing structured as custom quotation-based contracts that are not publicly disclosed. The company's aerospace and defense industry customers rely on its capability to process titanium alloys, high-temperature alloys, high-strength steel, and aluminum alloys into large structural components. In 2026, the company signaled early international expansion through its exhibition at the UK Farnborough Airshow, while recent stock price movements during 2026 US-Iran geopolitical events (an 18% decline in March 2026, a 3.26% rise on March 2, 2026) reflect market sensitivity to Chinese defense sector sentiment.
