Global FRP Central Strength Member (CSM) Market Strategic Research Report

Scope of the Report

The global FRP Central Strength Member (CSM) market size is predicted to grow from US$ 263 million in 2025 to US$ 402 million in 2032; it is expected to grow at a CAGR of 6.1% from 2026 to 2032.

FRP Central Strength Member (CSM) for fiber optic cables are non-metallic load-bearing rods made from a resin matrix reinforced with continuous fibers. They mainly include GFRP, reinforced with glass fiber, and KFRP, reinforced with aramid fiber. These rods are used as central or embedded strength members in optical fiber cables to provide tensile strength, bending resistance, electrical insulation, corrosion resistance, and dimensional stability.

Market Size: In 2025, global production of FRP Central Strength Member (CSM) reached 35.90 million kilometers, with an average selling price of US$7.5 per kilometer and total production capacity of approximately 45.00 million kilometers. Gross Margin: The industry gross margin is approximately 20%–30%. Cost Structure: Direct materials account for approximately 60%–75%, manufacturing overhead accounts for approximately 15%–25%, and labor costs account for approximately 5%–10%. Industry Chain: The upstream includes glass fiber yarn, aramid fiber/aramid yarn, epoxy resin/unsaturated resin, curing agents, coating materials, and other raw materials, while the downstream consists of fiber optic cable manufacturers.

The development of the global FRP Central Strength Member (CSM) market is fundamentally driven by the long-term rigid demand for global communication infrastructure construction. Broadband network upgrades and large-scale deployment of new-generation communication technologies led by governments worldwide form continuous demand transmission across the industrial chain, laying solid fundamental support for market growth. With performance advantages from its material properties, FRP CSM replaces traditional material products in complex application scenarios, with its application scope expanding from civil communication backbone and access networks to private communication networks in multiple industries, continuously broadening the market’s long-term growth boundary. The regional layout trend of the global industrial chain, coupled with technological iteration and production capacity support at the raw material end, directly affects the market supply pattern. Stable raw material supply and mature large-scale production capacity are key for market participants to build core competitiveness. Changes in the global trade environment improve regional industrial chain supporting systems, reshaping the market’s regional competitive landscape. Meanwhile, the continuous upgrading of technical standards and environmental compliance requirements in the global communication industry drives product technology iteration, and products meeting higher standards and compliance rules become the core direction of market development, further raising the industry’s overall competitive threshold.
