Marine and coastal infrastructure—including piers, seawalls, docks, and bridges—is constantly exposed to some of the most aggressive environmental conditions: saltwater, moisture, chlorides, and varying temperatures. One of the most persistent and costly problems in these environments is steel rebar corrosion in reinforced concrete structures. Glass Fiber Reinforced Polymer (GFRP) rebar, also referred to as composite rebar or non-metallic reinforcement, offers a highly effective and scientifically validated alternative to traditional steel rebar in marine applications. This article explores how GFRP addresses corrosion challenges in marine construction, with data, case studies, and lifecycle comparisons. The Corrosion Challenge in Marine Construction Steel rebar corrodes in chloride-rich environments, which leads to: Expansion and cracking of concrete Reduced load-bearing capacity Shortened service life Expensive maintenance...

In modern civil engineering and infrastructure development, the selection of reinforcement material has a profound impact on the durability, cost, and overall performance of concrete structures.
