According to our (Global Info Research) latest study, the global Thermosetting Direct Roving market size was valued at US$ 3400 million in 2025 and is forecast to a readjusted size of US$ 3944 million by 2032 with a CAGR of 2.0% during review period.
Thermosetting direct roving is an untwisted continuous fiberglass roving made by gathering continuous glass filaments, applying a thermoset-compatible sizing system and winding the strand onto packages. It is mainly designed for unsaturated polyester, vinyl ester, epoxy, phenolic and polyurethane resin systems. Key upstream materials include silica sand, pyrophyllite, limestone, boron minerals, soda ash, kaolin, alumina, silane coupling agents, epoxy or polyurethane film formers, lubricants and thermoset-compatible sizing formulations. The product is valued for low fuzz, stable tension, fast wet-out, resin bonding and mechanical performance. It is widely used in pultrusion, filament winding, weaving, knitting, prepregs, vacuum infusion and composite reinforcement, with downstream applications in pipes, tanks, pressure vessels, construction profiles, wind blades, marine, rail transit, industrial equipment, insulation components and corrosion-resistant composites.
In 2025, global thermosetting direct roving production reached approximately 4 million tons, with an average global market price is $800 per ton.
From a global industry perspective, thermosetting direct roving is a core base material for continuous-fiber-reinforced thermoset composites. Compared with assembled roving, direct roving is generally supplied as a single-end continuous package, offering more stable unwinding tension, lower fuzz and better fiber-orientation consistency, making it particularly suitable for pultrusion, filament winding, weaving and other continuous reinforcement processes. Johns Manville describes direct roving as single-end roving and states that direct roving for thermoset composites is used in pultrusion and woven fiberglass fabrics, with silane-based sizing to ensure compatibility with thermosets such as UP, VE and epoxy resins. Therefore, the value of this product is not limited to fiberglass strength; it directly affects resin impregnation, laminate quality, part strength, production efficiency and long-term durability.
In terms of industry trends, thermosetting direct roving is moving toward higher strength, more stable tex, faster wet-out, lower fuzz, fewer breaks, uniform unwinding, resin-specific sizing and higher glass-content processing compatibility. Traditional direct rovings focused mainly on tensile strength, linear density and price, while customers in pultruded profiles, filament-wound pipes and tanks, wind components, marine composites and multiaxial fabrics increasingly evaluate sizing formulation, unwinding tension, filament damage control, resin penetration speed, package formation and batch consistency. 3B Fibreglass describes direct rovings as continuous filaments bonded into a single strand and wound onto a bobbin, suitable for composite processes such as filament winding, pultrusion, knitting, weaving, texturisation and long-fiber technologies.
The main growth drivers come from three areas. First, pultruded profiles, gratings, composite rebar, cable trays, window and door profiles, electrical insulation parts, pipes, tanks and infrastructure composites continue to require high-strength, corrosion-resistant, dimensionally stable and continuously processable fiberglass reinforcement. Second, wind turbine blades, marine composites, pressure vessels, high-pressure pipes, rail transit and industrial structural parts are raising requirements for lightweighting, load-bearing capability and fatigue resistance, pushing direct roving toward higher strength, faster wet-out and stronger consistency. Third, downstream composite manufacturers increasingly focus on automation efficiency, mold turnover, resin wet-out speed, glass loading, laminate-defect control and batch stability, turning thermosetting direct roving from an ordinary fiberglass roving into a critical intermediate material affecting thermoset composite strength, appearance, processing efficiency and long-term reliability.
