Drivers and Trends
High Infrastructure Spending: A key factor driving the U.S. GFRP rebar market demand is the particular attention placed on modernizing and rebuilding the aging infrastructure of the country. Many of the roads, bridges, and public works have been described as in a 'rusting' stage, and hence serve as a reason for undertaking huge investment projects, and even infrastructure. As such, there is a need for advanced construction materials and frameworks that have better durability and demand less future maintenance.
The use of GFRP rebar is gaining traction in these large-scale projects due to its ability to withstand corrosion, a major cause of concrete deterioration. According to a report from USAFacts, the federal government spent around $146.2 billion on transportation and infrastructure in fiscal year 2023. A significant part of this funding, about 38%, was dedicated to highways. These investments in new and improved infrastructure projects, such as bridges and highways, are directly increasing the demand for durable materials that can handle the harsh conditions, thus driving the U.S. glass fiber reinforced polymer rebar market forward.
Growing Need for Corrosion-Resistant Materials: Reinforced structures with traditional steel GFRP rebar have experienced an increase in traditional issues, such as corrosion. A common GFRP rebar within construction practices is the conventional steel rebar. In most cases, the rebar leads to rusting and is exposed to moisture and chlorides, such as de-icing granules, or other chemicals. Correlating moisture with the conventional steel rebar results in rust, which, as a result, expands, leading to cracking of the concrete. This further damages the infrastructure and even causes structural failures. This is most prominent in coastal states or northern areas with heavy use of road salts in winter.
The government of the U.S. actively seeks solutions to address this problem, which poses a significant financial burden. A bill introduced in the House of Representatives, called the "Bridge Corrosion Prevention and Repair Act of 2023," highlights the importance of addressing corrosion in bridge projects that receive federal aid. This bill reflects the national focus on methods to control and prevent corrosion, including the use of rust-resistant materials. This focus on long-term durability and corrosion prevention is directly leading to more projects using GFRP rebar, which, in turn, fuels its market growth.
Segmental Insights
Resin Type Analysis
Based on resin type, the segmentation includes vinyl ester, epoxy, and others. The vinyl ester segment held the largest share in 2024. This is due to the favorable balance of mechanical and thermal property combinations of vinyl ester resins used for construction. Such resins endure exposure to difficult and severe corrosive environments often encountered in marine and other industrial environments. The resin's capacity to form chemical bonds with the glass fibers also enhances the overall strength and durability of the rebar. This makes the rebar a reliable construction material for infrastructure projects with stringent durability requirements.
The epoxy resin segment is anticipated to register the highest growth rate during the forecast period. Although its market share currently is not the largest, the demand for epoxy-based GFRP rebar is on the rise. This growth is attributed to its high strength and bonding, which are crucial for construction. Epoxy resins are mechanical optimals and are used in high-performance systems overwhelmingly. Continuous advancements in epoxy resin technologies and the use of these in complex projects would drive the expansion of this segment.
Tensile Strength Analysis
Based on tensile strength, the segmentation includes low strength and high strength. The low strength segment held the largest share in 2024. Low-strength GFRP is used in construction applications that do not primarily require extreme tensile strength. Examples of such constructions include residential slabs, sidewalks, and other low-volume infrastructures. The durability and corrosion resistance of the construction are acceptable and are provided at a lower cost than high-strength materials. The volume of these residential and small-scale construction projects increases the demand for this type of rebar. With its high penetration in the market, low-strength GFRP rebar is used in everyday construction and public works. It is the dominant part of the market by volume and revenue.
The high-strength segment is anticipated to register the highest growth rate during 2025–2034 due to its application in more sophisticated and challenging engineering works. High-strength GFRP rebar possesses better tensile properties than steel, making it more advantageous in critical applications. Its use is common in the construction of bridges, tunnels, and marine structures, where it is heavily loaded and subjected to extreme conditions. Increased government funding for the construction of reliable, large-scale structures that can withstand corrosion is fueling demand for this material. Its adoption in long-life, low-maintenance structures is driven by the material's high performance.
Diameter Analysis
Based on diameter, the segmentation includes <10mm, 10-20mm, and >20mm. The 10–20mm segment held the largest share in 2024. This specific size range is extremely useful and acts as a substitute for the most commonly used steel rebar diameters in a standard concrete construction project. This is employed in diverse areas such as the construction of buildings, highways, bridge decks, and even commercial buildings. The weight-to-strength-to-cost ratio makes these diameters the first choice among engineers and contractors trying to avoid the use of steel while still adhering to the building codes. Thus, 10-20mm is the most purchased diameter range in construction due to its broad applicability and high demand across various construction types.
The <10 mm segment is anticipated to register the highest growth rate during the forecast period. This is due to the fact that these smaller-diameter rebars are being increasingly used in specialized and non-conventional applications. Being light and easy to handle, these rebars are gaining use in small construction works such as residential patios, sidewalks, and flatwork, where light and easy-to-handle construction material is a huge plus. There is also an increase in other novel construction uses, such as in thin precast concrete panels and in modular construction systems. As builders and designers search for ways to optimize the construction process and reduce the weight of a structure, the use of these small-diameter rebars is increasing.
Application Analysis
Based on application, the segmentation includes highways & bridges & buildings, marine structures & waterfronts, water treatment plants, and others. The highways & bridges & buildings segment held the largest share in 2024. This is primarily attributable to the vast scale of construction and restoration activities in the region. Substantial amounts of both public and private investment in infrastructure are aimed at the construction and maintenance of roads, bridges, and other buildings, in addition to residential and commercial structures. This application area leverages a unique advantage of GFRP rebar due to its resistance to corrosion, which is a major issue regarding steel in these structures, especially due to the deicing salt usage on highways and the exposure to the elements. The large number of projects from U.S. steel merchants and rebar makers makes them the biggest users of GFRP rebar, giving them a strong lead in the market.
The marine structures and waterfronts segment is anticipated to register the highest growth rate during the forecast period. This is due to the specific marine conditions under a saltwater and moisture environment, which swiftly degrade the steel. GFRP rebar's resistance to corrosion makes it an appealing option, which is a major driver of the market. As coastal cities build new piers, seawalls, and other waterfront properties, there is growing demand for materials that require minimal routine maintenance. Such applications benefit from the material's long-term durability, resistance to chemicals and salt water, resulting in faster adoption and growth rates for that segment.
