Empowering Precision, Defining Efficiency.
E-glass Woven Roving Cloth (EWR) is a high-quality reinforcement fabric made from E-glass direct roving woven in plain or twill styles. This tightly woven cloth provides excellent mechanical strength, durability, and uniform resin absorption, ensuring consistent composite performance.
Widely used in manufacturing FRP boats, surfboards, tanks, swimming pools, automobiles, sailboards, panels, and other fiberglass-reinforced products, EWR is ideal for applications requiring reliable strength and long-lasting durability.

▪ Material: High-strength E-glass direct roving fibers
▪ Weave Types: Tightly woven in plain or twill weave patterns for uniform fiber alignment and load distribution
▪ High Strength: Provides excellent tensile and flexural properties in both warp and weft directions
▪ Dimensional Stability: Tight weave prevents fiber shifting and fabric distortion during handling and curing
▪ Impact Resistance: Woven structure enhances fatigue and impact performance in finished composites
▪ Resin Systems: Compatible with polyester, vinyl ester, and epoxy resins
▪ Manufacturing Methods: Suitable for hand lay-up, spray-up, and filament winding processes
▪ Uniform Resin Absorption: Even fabric structure promotes fast and consistent resin wet-out for high-quality laminates
▪ Marine: FRP boat hulls, decks, and structural panels
▪ Sports Equipment: Surfboards, sailboards, and other recreational composites
▪ Industrial Tanks: Chemical storage tanks, water tanks, swimming pools
▪ Automotive: Structural reinforcement components and body panels
▪ Construction: Composite wall panels and architectural elements
▪ Combine with other fabrics (e.g., chopped strand mat, biaxial fabrics) to tailor laminate properties
▪ Choose appropriate resin systems based on environmental exposure for enhanced corrosion resistance
▪ Optimize fabric areal weight and layering sequence according to load requirements and cost considerations
One roll is wrapped in plastic film and then placed into a carton or a large carton.
Normally, P4 (4 big rolls) or P7 (4 big rolls + 3 small rolls) or 6, 9, or 12 small rolls are packed per pallet horizontally/vertically. It can be customized based on the loading method.
Fiberglass products should be stocked in a dry, cool, and waterproof place. The best condition is with a temperature between 15-35℃, with a relative humidity between 30%-65%. Please keep the product in its original packaging before use, avoiding moisture.
Weitong currently operates over 30 fiberglass weaving machines for producing woven roving, along with various other equipment, including stitched mat machines, multiaxial tricot machines, PP core mat machines, and carding machines. Our annual production capacity reaches 3,000 tons of woven roving, 5,000 tons of stitched mat, 10,000 tons of multiaxial fabrics, 8,000 tons of combo mat, and 2,000 tons of RTM core mat.
Our team has already attended the China(Shanghai) International Composite Exhibition for 9 years, and JEC France, Composites Europe, and JEC Asia several times in France, Germany and Korea.
Backed by a highly skilled team of professional technicians, we have strong capabilities in developing and customizing specialized products to meet diverse customer requirements.
