Taishan Fiberglass

What Taishan Fiberglass does

Taishan Fiberglass (泰山玻璃纤维有限公司, also known as CTG) is one of the world's largest fiberglass manufacturers, established in 1997 in Tai'an, Shandong Province, China, and currently operating as a wholly-owned subsidiary of Sinoma Science & Technology Co., Ltd. (SZ002080), itself a subsidiary of state-owned China National Building Materials Group (CNBM). The company built China's first 10,000-ton/year alkali-free fiberglass tank furnace production line in 1997 and has since expanded across four manufacturing bases (Tai'an headquarters, Zoucheng, Zibo, and Taiyuan), reaching a combined fiberglass production capacity of approximately 1.7 million tons per year, ranking #2 globally and #1 in China. The firm employs 5,001-10,000 people and reports total assets exceeding RMB 27 billion, with annual sales revenue approaching RMB 10 billion.

The product portfolio spans 59+ categories and approximately 1,500 specifications, organized around process-based fiberglass solutions (pipes & tanks, wind energy, open molding, pultrusion, continuous panel molding, compression molding, mats & fabrics, thermoplastics) plus electronic and industrial fiberglass yarns and fabrics. Specialty lines include high-modulus/high-strength fibers (HMG, S-1HM(TM) rovings, THM-1), low-dielectric glass fibers for high-frequency PCB applications (TLD-GLASS), GF/PP thermoplastic composite yarns and fabrics (Comtex), alkali-resistant Cem-FIL AR-Glass, and vacuum insulation panels. Underlying process technologies include proprietary hyper fiberglass furnace design, oxy-firing technology, specialty glassfiber bushing design, fiberglass surface modification, ultra-thin electronic fabric preparation, and reinforced platinum-rhodium alloy bushing manufacturing. Building products extend into fireproof and thermal insulation boards, wet-process mats, and composite plastic pallets.

Taishan Fiberglass operates a direct enterprise sales model with regional divisions covering all Chinese provinces and dedicated international sales teams serving Europe, North America, South America, the Middle East, and Asia-Pacific, supported by wholly-owned CTG North America Inc. (Covina, California) and Taishan Fiberglass Pty S.A. (South Africa). Revenue is generated through B2B hardware sales of fiberglass materials to industrial manufacturers in wind energy (including Dongfang Electric Wind Power, named 2025 Strategic Partner), automotive lightweighting, electronics/PCBs, construction, marine, chemical, and oil & gas sectors, with end customers across approximately 80 countries. Pricing is quote-based and not publicly disclosed. The company is led by Party Secretary and Chairman Hu Yuewu, with Liu Lifeng serving as Deputy Party Secretary and General Manager.

Direct peers

• Jushi Group: China-based world's #1 fiberglass producer with broader capacity than Taishan. Most direct competitor across E-glass rovings, high-modulus fibers, and electronic fabrics for the same end markets (wind, auto, electronics, construction).
• Nippon Electric Glass: Japanese specialty glass manufacturer producing glass fiber reinforcement and electronic-grade fiberglass fabrics. Most directly comparable to Taishan's high-end electronic and low-dielectric product lines for PCB applications.
• CPIC Fiberglass: Chinese fiberglass manufacturer (subsidiary of China Petrochemical Corp / Sinopec) and another domestic Tier-1 player. Competes head-to-head with Taishan in E-glass rovings, chopped strands, and reinforcement materials for wind and auto in the Chinese market.

Broad incumbents

• Owens Corning: US-based global building materials incumbent with a large Composites segment producing fiberglass reinforcements. Direct overlap in rovings, mats, and electronic-grade fabrics; competes globally with Taishan especially in North America.
• Saint-Gobain (Vetrotex): French diversified building materials group with fiberglass reinforcement operations (Vetrotex). Competes with Taishan in European wind blade, automotive, and construction reinforcement markets, with broader product breadth across glass and other materials.
• Johns Manville: Berkshire Hathaway-owned US fiberglass and insulation manufacturer. Overlaps with Taishan in rovings, mats, and insulation products serving construction, industrial, and transportation end markets, particularly across the Americas.
• PPG Industries (Fiber Glass): US-based global coatings and specialty materials incumbent with a fiberglass reinforcement business. Overlaps with Taishan in chopped strands and reinforcement materials for transportation, marine, and construction.

Emerging players

• AGY Holding: US-based specialty glass fiber manufacturer focused on high-strength, high-modulus, and low-dielectric fibers for aerospace, electronics, and defense. Comparable to Taishan's specialty segments (S-1HM™, TLD-GLASS) but at smaller scale.

Regional players

• Sichuan Weibo New Material Group: Chinese fiberglass manufacturer focused on E-glass and alkali-resistant (AR) glass fibers. Comparable product mix to parts of Taishan's portfolio, particularly AR-glass and woven reinforcements, but at a smaller scale and primarily domestic focus.
• Binani Industries (Goa Glass Fibre): India-based fiberglass reinforcement manufacturer serving South Asian and Middle Eastern markets. Comparable to Taishan's commodity E-glass rovings and mats but with regional rather than global reach.
