Changshu Fengfan

What Changshu Fengfan does

Changshu Fengfan Power Equipment Co., Ltd. (常熟风范电力设备股份有限公司), listed on the Shanghai Stock Exchange (SSE: 601700), is a Chinese manufacturer of ultra-high voltage (UHV) power transmission towers and grid infrastructure steel structures, founded in 1993 and headquartered in Changshu, Jiangsu Province. The company's product portfolio spans angle steel towers (rated up to 1100kV), steel pipe composite towers, substation structural supports, steel pipe poles up to 220kV, custom steel structural components, and proprietary composite insulation towers — the latter being the only domestically-produced unit with independent intellectual property rights. Manufacturing is conducted across four branch factories covering approximately 458,000 square meters with 1,000+ pieces of automated equipment including CNC profile steel processing lines, JCOE straight seam welded pipe production lines, and hot-dip galvanizing lines, yielding a combined annual capacity of 400,000 tons (expanded to ~480,000 tons following the 2023 new line addition).

The business model is enterprise field sales through competitive bidding on utility tenders, with primary customers being State Grid Corporation of China and China Southern Power Grid, alongside provincial grid operators and international EPC contractors. Pricing is project-based, determined through competitive bidding on customized specifications, with multi-year supply contracts. The company holds ISO 9001 (first in industry), ISO 14001, ISO 45001/BS-OHSAS 18001, national steel structure first-class qualification, and foreign contract engineering qualification. It maintains channel relationships with international infrastructure partners (DOWNER, Powerlink, Reliance, Transfield, Balfour Beatty, John Holland, TransGRID) and a 2020 logistics partnership with Beijing COSCO Shipping, exporting to over 60 countries including Algeria, Pakistan, Egypt, Chile, and Australia.

Revenue reportedly reached 2 billion CNY in 2019 (≈$280M USD), with international revenue accounting for approximately 45% of total. Operational subsidiaries include Fengfan Green Building (cold-formed steel), Jiangsu Fenghua Energy (energy trading), Fengfan Asset Management, Fengfan International Engineering (EPC), and a Sino-Pakistan joint venture for Belt and Road hydropower investment. Recent strategic direction has emphasized international EPC general contracting (Chile Strait Crossing win, 2019), capacity expansion (new 80,000-ton steel pole line, 2023), and a leadership transition from founder Fan Jiangang to Fan Liyi as Chairman and General Manager in 2021. Reported financials for 2024-2025 show operating losses and deteriorating net income, indicating cyclical pressure on UHV capex and pricing.
