Glass Fiber Reinforced Polymer (GFRP) rebar and mesh are composite materials developed to be used in place of the conventional steel reinforcement in concrete structures. They consist of continuous glass fibers dispersed within a polymeric resin matrix, most commonly epoxy, vinyl ester, or polyester. The synergy between the tensile strength of glass fiber and the corrosion inhibition properties of polymers produces reinforcement products that are light weight, corrosion-free, and extremely durable. GFRP rebar and mesh have high tensile strength-to-weight ratios, electromagnetic neutrality, and alkali resistance, which make them ideal for use in long-term infrastructure. They are produced using pultrusion, filament winding, or molding to form the rebars, and surface treatments for better bonding with concrete. They are used in wide-ranging applications from bridges, highways, and tunnels to marine structures, industrial floors, and precast concrete products, where long-term durability and low maintenance are essential. Economic benefits incorporate lower lifecycle expenses as a result of less frequent repair requirements and convenient handling. Increased global focus on sustainable building translates to greater use of GFRP products for increased service life, minimized carbon footprint, and lower logistics. Future prospects are bright, with increasing adoption in intelligent infrastructure and climate-resilient constructions globally. The United States Glass Fiber Reinforced Polymer (GFRP) rebar and mesh market size reached USD 210.6 Million in 2024. According to IMARC Group, the market is projected to reach USD 561.6 Million by 2033, at a CAGR of 11.3% during 2025-2033. The GFRP rebar and mesh industry is driven primarily by the growing demand for corrosion-resistant substitutes for steel reinforcement, particularly in marine and coastal structures where chloride-induced corrosion is a key challenge. Growing investment in infrastructure, notably in bridges, highways, and urban public transport networks, is a key growth driver. The lightweight nature and handling ease minimize construction time and cost to support greater uptake. Another force behind the growth is the increasing demand for non-magnetic reinforcement in hospitals, defense buildings, and laboratories. Future trends involve the coupling of GFRP with intelligent sensing technologies to facilitate structural health monitoring. The next five years will witness high growth rates in developing economies, especially Asia-Pacific and the Middle East, where infrastructure projects are large-scale in nature. Advantages are high strength, lower lifecycle costs, and meeting tight sustainability targets. Challenges are in increased initial cost compared to steel and limited contractor familiarity. Sustainability drivers are favorable, with GFRP greatly reducing repair time and energy-consumptive steel use. The market is reacting with standardization of design codes, increased production capacity, and collaborations between composite producers and construction companies to drive adoption.
One of our clients reached out to us to conduct a feasibility study for setting up a large-scale Glass Fiber Reinforced Polymer (GFRP) rebar and mesh manufacturing plant. We developed a comprehensive financial model for the setup and operation of a proposed Glass Fiber Reinforced Polymer (GFRP) rebar and mesh manufacturing plant in United States. This plant is designed to produce 2,722 tons of Glass Fiber Reinforced Polymer (GFRP) rebar and 144 tons of Glass Fiber Reinforced Polymer (GFRP) mesh annually.
Manufacturing Process: The process of Glass Fiber Reinforced Polymer (GFRP) rebar and mesh production is almost the same, differing in how they are shaped. The process starts with the preparation and creeling of fibers, where glass fibers are stretched in a continuous form (rovings) and aligned under tension for stability and strength. Fibers are then passed through a bath of resin, which saturates them with thermosetting polymers like epoxy, polyester, or vinyl ester, often supplemented with additives. In rebars, the resin-coated fibers pass through a preforming die which compresses them to the required profile, and in mesh, fibers are positioned in perpendicular grids with automated machines and bonded at intersections. The impregnated material proceeds to be cured in a heated die or oven, where heat is controlled to trigger polymerization that rigidizes the composite in its final form. After curing, products are subjected to surface treatments like sand coating or helical wrapping to improve concrete bonding. Cut rebars or mesh are cured and then cut to exact lengths or panel sizes, occasionally coiled into rolls for shipping. Stringent quality control testing confirms ASTM and ACI compliance, assessing strength, size, and bonding characteristics. Lastly, rebars and mesh are wrapped for protection and stored in pallets or wrapping and labeled for traceability to be shipped to construction sites.
Mass Balance and Raw Material Required: The primary raw materials used in the Glass Fiber Reinforced Polymer (GFRP) rebar and mesh producing plant are glass fiber rovings, epoxy resin, and additives and hardeners. For a plant producing 1 ton of Glass Fiber Reinforced Polymer (GFRP) rebar, 0.720 ton of glass fiber rovings, 0.260 ton of epoxy resin, and 0.057 ton of additives and hardeners is required. For a plant producing 1 ton of Glass Fiber Reinforced Polymer (GFRP) mesh, 0.680 ton of glass fiber rovings, 0.290 ton of epoxy resin, and 0.059 ton of additives and hardeners is required.
