- CSG Holding Co., Ltd. engages in the research, development, production, and sales of energy-saving glass, solar photovoltaic products, and ultra-thin electronic glass and display devices. Its main product lines include high-quality float glass such as ultra-clear, ultra-wide, ultra-thick, and ultra-thin variants; architectural engineered glass including low-E glass, laminated glass, tempered glass, and anti-reflective glass; solar glass with properties of high solar transmittance and mechanical strength used in photovoltaic and thermal applications; ultra-thin electronic glass including medium-aluminum and high-aluminum glass for displays; and renewable energy products encompassing high-purity polysilicon, high-efficiency silicon wafers, crystalline silicon solar cells, and photovoltaic modules. The company also provides integrated services for development, construction, operation, and maintenance of photovoltaic power plants. Founded in 1984 and headquartered in Suzhou, China, CSG Holding operates primarily in China and serves both domestic and international markets, with well-recognized brands and patented technologies supporting its position as a leading glass manufacturer.
In recent developments, the company has authorized a significant share buyback plan and reported robust sales from its subsidiaries, including large-scale deliveries of specialized glass products to industry giants such as LONGi Green Energy Technology. In October 2025, CSG Systems International, a related entity listed on NASDAQ, agreed to be acquired by NEC Corporation for approximately $2.9 billion, a move expected to expand NEC's digital and cloud offerings while complementing CSG's existing portfolio. This strategic alliance is poised to enhance technological innovation and market reach in the SaaS and software services space. Despite facing some revenue and profit fluctuations in 2025, CSG remains focused on product innovation and expanding its new energy business segments, continuing to leverage its extensive patent portfolio and national technology center accolades to maintain competitiveness in high-end architectural glass, photovoltaic materials, and ultra-thin electronic glass markets.
CSG Holding is also noted for its contributions to national and industrial standards in glass manufacturing, boasting nearly 2,000 patents and technological expertise that drives industrial innovation. Its product suite supports urban landmark constructions and high-rise buildings in major Chinese cities, underpinning its reputation and market leadership in energy-efficient and high-performance glass solutions.
