Last week, we were thrilled to exhibit at the 29th China International Composites Expo (CCE 2026) in Shanghai – and what an incredible experience it was!As a dedicated manufacturer of fiberglass woven roving, chopped strand mats, and fiberglass fabric, we enjoyed reconnecting with our valued partners and meeting many new friends from the global..

Woven roving or chopped strand mat? Compare strength, weight, resin use, surface finish and cost — plus when to combine both.

We are excited to announce that Jiashan Shantong Weaving Co., Ltd. will be exhibiting at the China Composites Expo 2026 this September in Shanghai. As a specialized manufacturer and trusted supply partner for fiberglass products, we warmly invite you to visit our booth to explore our latest offerings and discuss how we can support your business growth.

Learn what Fiberglass Core Mat is, its sandwich structure, key properties, and applications in RTM, vacuum infusion, marine, automotive and aerospace industries.

The short answer: for standard hand lay-up with unsaturated polyester resin, plan for approximately 1.5 kg of resin per 1 kg of woven roving — a 1.5:1 resin-to-fiber ratio by weight. But that number changes depending on your fabric weight, resin system, and manufacturing process.

The process begins with continuous glass fiber rovings — bundles of thousands of individual glass filaments drawn from molten glass. The linear density (tex value) of each roving bundle directly determines the final fabric weight (g/m²). For example:

Everything you need to know about fiberglass woven roving — types, weight specs, resin compatibility, applications, and how to choose the right grade. From a manufacturer since 2002.

Fiberglass composites are widely used in boats, ships, and aircraft due to their corrosion resistance and lightweight properties.

Fiberglass is a critical material in modern engineering, offering a unique combination of strength, durability, and versatility. Future advancements aim at improving recyclability and reducing production costs.

Fiberglass is revolutionizing the construction industry by offering lightweight, durable, and corrosion-resistant alternatives to traditional materials like steel and concrete.
