One of the primary determinants of FRP rod pricing is the cost of raw materials used in their production. The key components of FRP rods include fibers (such as glass, carbon, or aramid) and resin. Fluctuations in the prices of these materials, driven by global supply chains, mining, and production activities, directly impact the overall cost. For instance, if the price of carbon fiber rises due to increased demand from the aerospace sector, the manufacturing cost of carbon FRP rods will also increase, subsequently raising market prices.
