High-Performance Woven Roving for Strength, Versatility, and Cost-Efficiency

Unmatched Tensile Strength and Reinforcement

Rondy’s woven roving delivers exceptional mechanical reinforcement for composite applications, thanks to its tightly interlaced glass fiber strands. Engineered to withstand heavy loads and structural stress, our roving enhances the durability of fiberglass-reinforced plastics (FRP), marine hulls, automotive components, and industrial equipment. With consistent fiber alignment and high strand count, it ensures uniform strength distribution, reducing the risk of cracking or failure in critical applications.

Superior Resin Infusion and Compatibility

Designed for optimal resin wet-out, Rondy woven roving absorbs and distributes resins evenly, minimizing voids and improving composite integrity. Compatible with polyester, vinyl ester, and epoxy resins, our roving is ideal for hand lay-up, filament winding, and pultrusion processes. This versatility makes it a go-to choice for manufacturers across industries, from aerospace to construction, seeking reliable reinforcement materials.

Precision Engineering for Consistent Quality

Manufactured using advanced texturizing and sizing technologies, Rondy woven roving offers uniform thickness, weight, and fiber orientation in every roll. Our stringent quality control processes ensure low fuzzing, minimal yarn breakage, and consistent performance batch after batch, reducing waste and enhancing production efficiency for our clients.

Cost-Effective Performance Without Compromise

Rondy balances premium quality with competitive pricing, providing woven roving that outperforms generic alternatives in strength and durability while keeping costs manageable. Our large-scale production capabilities and streamlined supply chain enable us to offer bulk pricing without sacrificing material excellence, making us a trusted partner for businesses prioritizing value.

The company’s woven roving products feature diverse textures tailored to specific applications. Designed with interlaced fiberglass strands, these textiles offer high tensile strength and resistance to deformation. The texture variations enhance compatibility with different resins and molding processes, making them suitable for applications ranging from industrial tanks to architectural reinforcements, where both strength and surface finish are critical.

Frequently Asked Questions

What industries benefit most from Rondy woven roving?

Rondy woven roving is widely used in industries requiring robust composite reinforcement, including aerospace, automotive, marine, construction, and wind energy. It is ideal for manufacturing aircraft components, car body panels, boat hulls, structural beams, and wind turbine blades, where high tensile strength and dimensional stability are critical.
Unlike chopped strand mat (CSM), which uses randomly distributed short fibers, woven roving features continuous, parallel glass fiber strands woven into a bidirectional fabric. This structure provides higher tensile strength in specific directions, making it suitable for applications requiring oriented reinforcement. Rondy’s woven roving is preferred for load-bearing components, while CSM is often used for general-purpose layering.
Yes. Rondy woven roving is treated with specialized sizings that enhance resistance to moisture, UV radiation, and moderate heat. While its temperature tolerance depends on the resin system, the glass fiber itself maintains structural integrity in elevated temperatures, making it suitable for outdoor applications and industrial settings with consistent thermal demands.
Rondy offers customizable woven roving in various weights (e.g., 450 gsm to 1200 gsm), widths, and fiber diameters to meet specific project requirements. We also provide different sizing formulations tailored for compatibility with specific resins, ensuring optimal performance in diverse manufacturing processes.

customer evaluation

Emma L., Composite Materials Buyer
"Reliable Reinforcement for Aerospace Composites"

"As a supplier to aircraft manufacturers, we need woven roving that meets stringent aerospace standards. Rondy’s product delivers exceptional tensile strength and resin compatibility, ensuring our composite parts pass rigorous stress tests. The consistency in quality across batches has been a game-changer for our production line."

Carlos M., Boat Builder
"Durable and Easy to Work With in Marine Applications"

"We’ve used Rondy woven roving in hundreds of boat hulls, and it never disappoints. The tight weave prevents resin bleed-through, and the fibers wet out smoothly, reducing labor time. Our clients notice the improved impact resistance, especially in rough marine environments. Highly recommended for anyone in the marine composites industry."

Li Wei, Production Manager
"Cost-Effective Solution for Large-Scale Construction Projects"

"For our wind turbine blade manufacturing, we needed a high-strength roving that didn’t break the budget. Rondy’s woven roving offers the perfect balance of performance and cost. The large roll sizes minimize downtime from reloading, and the consistent fiber alignment ensures uniform blade strength. Great value for high-volume production."

Sarah K., Automotive Engineer
"Exceptional Quality for Automotive Composite Parts"

"We switched to Rondy woven roving for our automotive body panels, and the difference in quality was immediate. The roving’s low fuzz and precise weave reduce post-processing defects, saving us time and money. Plus, their responsive customer service helped us quickly resolve a custom sizing request. Will definitely continue our partnership."
